Additive Manufacturing in the Quad Cities: At a Glance
What is “additive manufacturing?”
Additive Manufacturing (often referred to as simply “AM”) is the process of adding layers of material (plastic, metal, concrete, etc.) upon one another to create a product. You may also hear it referred to as “3D printing,” though that term only encompasses some of the processes that can be used in additive manufacturing.
Why does additive manufacturing matter to the Quad Cities?
Additive manufacturing has the capacity to complement and augment current manufacturing processes in the future. In three to five years, manufacturers in our region will plan for additive manufacturing opportunities from product inception through design and production, in order to increase efficiencies, save money, and rapidly prototype.
What are the biggest opportunity areas locally?
Traditional tooling, small weldments, low production runs, complex parts, and repair parts will see significant disruption. Learn more about opportunities in the Identify Opportunities section.
What are the business benefits of additive manufacturing?
Rapid innovation and prototyping, increased speed-to-market, lower tooling costs, unique designs, reduced part quantities, ability to embed sensors, multi-material designs, and a breadth of equipment to cover multiple applications are all benefits of implementing this technology. See more benefits in the Metrics for Success for Success section.
Where can I find help to get started?
Local experts from Western Illinois University, the Quad City6 Manufacturing Lab, and Eastern Iowa Community Colleges can help you find the right application of additive manufacturing that fits your needs. The Hub also holds periodic Additive Manufacturing User Group meetings (check the Chamber website for event details). For more information on the expert resources in the Quad Cities, visit Find Help with Regional Assets and Partners.
Understand the Technology
In the first section, we take a closer look at the variety of technologies that contribute to the collective term “additive manufacturing.” You’ll gain a better understanding of how AM processes work through diagrams, frameworks, and definitions of key terms used in the AM space. This section also details additional online resources for greater understanding.

Please refer to the glossary in the appendix for definitions of key additive manufacturing terminology that are utilized in this playbook. Definitions provided for educational purposes as described by TEAMM (Technology Education in Additive Manufacturing and Materials), unless otherwise noted.
Additional Online Resources
There are many online resources for review to deepen your understanding of additive manufacturing technologies, processes, opportunities, challenges, and more. We’ve outlined a few below:
“Standard Terminology for Additive Manufacturing Technologies” This terminology includes terms, definitions of terms, descriptions of terms, nomenclature, and acronyms associated with additive manufacturing technologies in an effort to standardize terminology used by AM users, producers, researchers, educators, press/media, and others. http://web.mit.edu/2.810/www/files/readings/AdditiveManufacturingTerminology.pdf
“What is additive manufacturing?” (video) GE Aviation is revolutionizing the age-old rules of manufacturing and design. Learn how additive manufacturing, a 3D printing technology, frees engineers to design the perfect jet engine.
From Loughborough University’s Additive Manufacturing Research Group:
“The 7 Categories of Additive Manufacturing” Although the term “3D printing” is often used as a synonym for all additive manufacturing processes, there are many individual processes that vary in their method of layer manufacturing. Individual processes will differ depending on the material and machine technology used. Hence, in 2010, the American Society for Testing and Materials (ASTM) group “ASTM F42 – Additive Manufacturing,” formulated a set of standards that classify the range of additive manufacturing processes into seven categories. http://www.lboro.ac.uk/research/amrg/about/the7categoriesofadditivemanufacturing/
Additive manufacturing offers many opportunities to small and medium manufacturers in the Quad Cities (see Figure 6, below). Of the myriad of opportunities, the Hub has identified three key opportunity areas that will bring greatest benefit to our area’s small and medium manufacturers: tooling, repair parts and legacy components, and prototyping.
Figure 6. Applications of Additive Manufacturing by Use Case4
Applications of Additive Manufacturing
4 Wohler’s and Associates Report 2017
Opportunity #1: Tooling
Utilizing additive manufacturing, you can make tools that are either impossible to machine (complex or novel geometries) using traditional subtractive methods, or extremely expensive to machine. AM offers efficiencies in tooling production time, strength and durability in parts, higher quality finish, as well as the ability to combine multiple parts into one single print––all, of which, can positively impact return on investment over traditional manufacturing methods. Tooling with additive can be completed using a variety of materials, including nylon, fiber, and metals. Many manufacturers use AM to print one-off, custom parts as well to quickly solve in-house tooling issues as they arise.
Opportunity #2: Repair Parts and Legacy Components
As additive manufacturing is quick and flexible in its applications, many manufacturers use it to either update legacy components or efficiently replace parts in need of repair that would typically take much longer (and more investment due to set-up costs and large batch requirements) to cast a mold and print either in-house or overseas. By depositing new material using AM onto an existing part, it can not only create new use cases for tooling but also extend the lifetime of the part. If manufacturers do not have a 3D model of a legacy part or one in need of repair, there are local resources that can assist in 3D-scanning solid models, as well as taking measurements in order to remodel a part (see Educational Resources).
Opportunity #3: Prototyping
Additive manufacturing provides the opportunity to learn quickly, fail early, and move on to the next innovation due to its production speed and low cost in small-batch runs. Traditionally, manufacturers become comfortable with long lead times and large runs of parts, incrementally inspiring less in-house R&D and innovation over time as it doesn’t seem “worth the trouble” if it isn’t successful. AM offers ultimate flexibility for prototyping new ideas for innovation in tooling, repair parts, fixtures, legacy equipment, and more. And, with both materials and hardware technology costs decreasing, the opportunities presented by quick and easy prototyping, and immediate problem-solving, will only continue to grow.
Benefits and Use Cases of Additive Manufacturing Opportunities
As the cost of international logistics continues to rise, and additive manufacturing becomes more affordable, Quad Cities manufacturers have the opportunity to shift facilities and production back to U.S. and local locations. This offers many benefits to small and medium manufacturers, including lower inventory levels as products are made in smaller batches and closer to “on-demand,” and direct-to-consumer fulfillment opportunities.5
Let’s examine the key benefits of utilizing additive manufacturing in each of the three opportunity areas previously identified. Below, you’ll also find a case example for each opportunity area that shows how a manufacturer was able to utilize AM to produce better results than traditional subtractive methods.
Works best with low-volume production needs, complex parts, and those that would normally be of high cost to create using traditional manufacturing methods.
Surrogate parts created using AM allow employees to practice on lightweight versions before casting is complete on actual part. This can be beneficial for safety training, ergonomics, proofs of concept, and other technician-training aids.
Significantly cuts weight of tools to increase efficiency of operator setup time.
Minimized print time and material usage while maintaining strength of tool. This can translate to high-cost savings.
Case Example: Deere & Company Significantly Cuts Tooling Costs by Using Additive Manufacturing to Create a Porous Support Structure
See table below for cost comparisons. Fused deposition modeling (FDM) tooling proved to be more cost-effective vs. traditional aluminum and medium-density fiberboard (MDF) tooling.
Opportunity #2: Repair Parts and Legacy Components
Part repairs can be made in-place to extend lifetime and/or create new use cases and upgrades to legacy components without the need for new castings
More efficient in-house component repair than replacing through distributor
Reduced waste generation during the repair process
Improved product utilization during repair and remanufacturing
Reduced replacement parts inventory, offering cost-savings in times of low demand6
Case Example: Siemens uses AM to Repair Burner Tips More Efficiently and with Less Waste
Siemens Power Generation Services (Siemens PGS) provides support, maintenance, and repair services to customers operating rotating power equipment such as gas steam and wind turbines, generators, and compressors. Having identified the combustion system in gas turbines as one particular application whereby AM could improve customer value in spare parts repair and manufacturing, Siemens PGS has redesigned the burner “swirler” to make use of the design freedoms afforded by AM. Through using AM the burner tip can be repaired more quickly and with less waste. It is estimated that the repair time is 10 times quicker than the previous approach. Less waste is generated as little of the burner is now discarded; only the top 18 mm edge of the burner tip is removed prior to repair. Using AM also allows for much easier upgrading to the latest design and is a step toward the business’ future vision of spare parts being manufactured on-demand, closer to the customer’s location.7
Cost-effectively test the function of a design, geometry, and fit-up with other parts before waiting the average 20-week lead time to cast and manufacture a tool. Prototyping can be done using in-house AM equipment or partnering with a local innovation lab (see Innovation Labs for details).
Test product markets to better understand what customers want and get in front of them faster.
Test manufacturing process, including assembly and tooling/fixtures. Print a mock-up before buying an expensive tool.
Use prototypes during discussions with suppliers as surrogates for discussion, planning, verification, and sales purposes.
Prototype large parts in multiple pieces using AM to ensure each part fits into manufacturing process without error.
Case Example: DePuy Spine uses AM to Speed Prototyping of Complex Surgical Tools
DePuy Spine makes more than 70 brand-name products with more than 10,000 product codes that are distributed globally. Using a single DMLS-machine from EOS in their own shop, DePuy Spine processed 2,000 prototype parts — benders, extractors, surgical screws, clamps, reduction devices and others — in the first year of use alone. This has accelerated the development of its medical instruments according to the consulting doctors’ requirements rather than manufacturability using traditional methods. Delivery times for surgical prototype tools have shrunk from several months to less than one week. The flexibility of CAD designs makes it easy to adjust to new requirements, and in-house production has saved DePuy Spine time and money.8
In this section, we’ll outline the steps to take in implementing additive manufacturing within your company, beginning with awareness and change management, through establishing partnerships and building use cases that will save you time and money. We understand that the idea of implementing AM is completely different from traditional subtractive manufacturing processes that you may be accustomed to, and that the prospect of this degree of change to your business model can be daunting or frightening. It is our hope that, through the following content and previous look at the benefits of AM, you’ll feel more comfortable exploring how you can utilize these technologies to bring production back in-house, into the region, and create new solutions for your customers.
Change Management Building the Case Requires Data and a "Test-and-Learn" Approach
For most small and medium manufacturers, the prospect of adopting AM seems risky, as it requires learning new equipment, technologies, and procedures to remain profitable. Only through experimentation, learning, and failing fast, can you quickly gain new expertise and experience that will benefit your company in years to come.
However, it is new technologies, like additive manufacturing, that are shifting the very structure of the manufacturing industry––beyond the Quad Cities. New business models are emerging, and the only way to survive is to be proactive in your adoption of AM in ways that fit into your production methods.
There are many ways for you to get started along the path to utilizing AM. Use the change management tips below to make the case for change and immediately begin proving results:
Understand the business value of additive manufacturing and set goals accordingly. Use our Metrics for Success as well as your own data research to set realistic expectations of how you will measure the impact and success of integrating AM into your existing manufacturing processes. This will help in resource planning if you’re measuring the right benchmarks out of the gate. Focus on one or two main use cases first before adding complexity to your production process and supply chain.
Focus on getting every employee on board with the benefits of AM through peer education. Get all stakeholders involved from the beginning via one-on-one conversations with leaders and all-company meetings to drive the vision. Make them as knowledgeable as you possibly can, taking ownership of AM initiatives. Innovative companies like GE promote “reverse mentoring” to foster understanding, create mutual empathy, and promote collaboration between disparate generations and team members. In reverse mentoring scenarios, a younger colleague mentors a more tenured employee as a way of getting everyone up-to-speed quickly with AM technologies and benefits. Visit Educational Resources for more tips.
Keep communication lines open during the trial-and-error portion of AM experimentation. Employees should understand that it’s okay to fail, and fail fast, if it’s part of a learning process that eventually leads to prototyping successful equipment, product, and tooling runs. This mindset must be led from the top down within your company in order for employees to feel like they can experiment and innovate in order to achieve efficiencies in AM. Breed risk-taking early.
Part of change management also lies in understanding and planning for the challenges you will encounter in integrating AM into your existing operations. Below are three challenges we’ve identified through our research and conversations with area manufacturers. Become familiar with the potential roadblocks so you can steer clear of their hindrances early on.
Longer print times: Depending on your application of AM, it may take longer to print an entire run of parts or tools due to the speed of the 3D-printer. For this reason, AM is best suited for small-batch runs and prototyping for many manufacturers.
Frequent firmware updates: The software utilized to communicate with AM machinery requires regular updates in order to perform correctly. You’ll need to plan for hardware and software resource allocation accordingly within your facilities.
Costly metal printing filaments and powders: Though the cost of smaller 3D-printers that output plastic or other polymer parts is declining, the cost of utilizing AM for metal parts is still quite steep. Manufacturers must conduct a cost/benefits analysis of printing efficiency, cost, labor, batch size, and delivery against traditional methods (either internally or outsourced). The feasibility of using AM for metal materials will vary by project and is dependent on cost structure.
Processes and Frameworks for Implementing Additive Manufacturing
Integrating AM into your existing manufacturing processes requires a strategic approach. Utilize the workflows and frameworks below to jumpstart your efforts.
Workflow 1: Additive Manufacturing Planning and Deployment Strategy9
Diagnose: Assess your current state of AM knowledge and create a vision for where your company should be in its use of AM in three to five years.
Define: Define your strategy and timeline for achieving your vision. Include resource planning and goals and metrics to define success.
Deploy: Develop and pilot priority initiatives to test AM capabilities and use cases. Embed new capabilities and upgrade necessary technologies and infrastructure.
Determine: Measure impact against predefined benchmarks and iterate on future AM uses. Continue this process iteratively.
9 Workflow adopted from Altimeter Group, a Prophet Company’s approach to jumpstart digital transformation.
Workflow 2: Tools Chain to Create a Process for Additive Manufacturing10
From Reinshaw: AM must be underpinned by an effective process chain with user-friendly design tools and a range of post-processing and metrology before the parts it makes can be used. Information must flow up and down the chain to link processes together.
Resources Needed: Technology and Staffing
Resources required to implement AM within your manufacturing facility will vary by the use cases you’ve established for the technology. For example, utilizing AM for rapid prototyping will yield a different cost structure for hardware, software, and staffing than planning to use AM as a replacement for all tool casting. As previously outlined, you must create a strategic plan for how AM will augment or replace your current manufacturing processes in the recommended opportunity areas of tooling, repair and legacy parts, and prototyping before jumping the gun and purchasing a series of 3D printers, updating software, and hiring unnecessary talent.
Use this general checklist to assist in the process of planning for your hard and soft costs in AM:
Hardware: The machinery you purchase will depend on how you plan to use AM within your manufacturing facility. Refer to the glossary in the Appendix to review the types of AM that are best suited for various use cases. Once you have decided on how you will utilize the machine, and what type of AM is best suited for your needs, begin the research process of purchasing one or more machines. Refer to the Regional Assets section for recommendations on local partners and vendors. Also review offerings from EOS, Stratasys, and Renishaw –– all reputable hardware vendors used by many local manufacturers, innovation labs, and OEMs.
America Makes also offers the Senvol Database, a comprehensive database of industrial additive manufacturing machines and materials. Users are able to search the database by more than 30 fields, such as machine build size, material type, and material tensile strength. Access the database here to aid in your selection process:
Software: AM begins with a CAD model, which often means there will be a small learning curve for engineers and designers in transitioning into the software specific to your AM machine. There are many modeling programs that can be used for AM and feature sets depend on your intended use. Use the framework below to begin deciding which software is right for your application(s) and continue research online.
Employees and Hiring: Assess your current employees for skillsets in CAD/CAM to determine if expertise is applicable and transferrable to your AM software choices. Most manufacturers have in-house talent that is ready and able to augment their current skills. However, some local small and medium manufacturers have opted to hire new employees with engineer and design expertise specific to AM in order to speed up the implementation process, as well as inject new approaches to innovation within the company. Work with the partners listed in Educational Resources to find inexpensive design and engineering talent either freshly graduated or as a temporary intern (with, ideally, intent to hire).
“Quick Wins” to Get Started with Additive Manufacturing
Take a page from the playbooks of local manufacturers like John Deere, Trackside Solutions, Ossian, and more that are already up-and-running with AM by following a few of their tips to jumpstart your use of the technology:
Start with brainstorming potential applications in tooling. What can you make that’s low volume and expensive to make traditionally? Also consider what would require otherwise complicated or impossible geometry using traditional methods. Those are your immediate opportunity areas! Utilize the worksheet below in Fig. 8 (available for high-resolution download here: https://joranbooth.files.wordpress.com/2015/10/dfam1.pdf) from Joran Booth to guide you through the process of designing parts for AM that will fit your needs and achieve your goals. It was created to quickly reduce the number of printing and prototyping failures.
Figure 8. Design for Additive Manufacturing Worksheet from Joran Booth
Gain experience through service bureaus. Visit Educational Resources for local partnership resources. Depending on your AM applications, it’s likely you’ll be able to make use of others’ assets during your planning and consideration phases. This will help you build the business case if you need to “sell” the idea of AM to leadership within your company.
Talk to machine resellers to better understand the pros and cons of each machine you’re considering purchasing. They’ll be able to tell you the ideal applications for each machine, material needs and tolerances, and if it fits with your production needs. Before making a large purchase, experiment with a cheaper 3D plastic printer. Get them in the hands of your engineers to begin rapidly innovating in real-time.
Reach out to people in the community. You’ve already taken the first step by reviewing the Quad Cities Manufacturing and Innovation Hub playbook. This playbook was drafted based on the input of our AM “Tech Team,” a group of local manufacturers that are currently implementing AM. You’re invited to attend any of our AM User Group meetings and Hub Huddles as well to network with other manufacturers and learn straight from the source how they’re using AM to augment or replace existing manufacturing processes to save time and money. Go to the Quad Cities Chamber of Commerce events web page (http://member.quadcitieschamber.com/events) for upcoming meeting information and registration.
Metrics for Success: How to Measure Impact
When setting your objectives for AM, you’ll need to tie goals to business impact using metrics for success. Without measuring and benchmarking the performance of AM against traditional manufacturing, it will be more difficult to consistently improve processes, assess weaknesses, and secure future resources.

Glossary: Key Additive Manufacturing Terms
Definitions provided for educational purposes as described by TEAMM (Technology Education in Additive Manufacturing and Materials), unless otherwise noted.
3D printer: machine used for 3D printing.
3D scanning: method of acquiring the shape and size of an object as a 3-dimensional representation by recording x,y,z coordinates on the object’s surface and through software, the collection of points is converted into digital data.
Build cycle: single cycle in which one or more components are built up in layers in the process chamber of the machine.
Build platform: of a machine, any base which provides a surface upon which the build is started and supported throughout the build process.
Build surface: area where material is added, normally on the last deposited layer which becomes the foundation upon which the next layer is formed.\
Computer-aided design (CAD): The use of computers for the design of real or virtual objects. The Quad Cities Manufacturing and Innovation Hub also offers a technology playbook dedicated to CAD/CAM.
Computer-aided manufacturing (CAM): Typically refers to systems that use surface data to drive CNC machines, such as digitally-driven mills and lathes, to produce parts, molds, and dies. The Quad Cities Manufacturing and Innovation Hub also offers a technology playbook dedicated to CAD/CAM.
Fused deposition modeling (FDM): Making of thermoplastic parts through heated extrusion and deposition of materials layer by layer. A plastic filament is unwound from a coil and supplies material to an extrusion nozzle. The nozzle is heated to melt the plastic and has a mechanism which allows the flow of the melted plastic to be turned on and off. The nozzle is mounted to a mechanical stage which can be moved in both horizontal and vertical directions. As the nozzle is moved over the table in the required geometry, it deposits a thin bead of extruded plastic to form each layer. The plastic hardens immediately after being squirted from the nozzle and bonds to the layer below. The entire system is contained within a chamber that is held at a temperature just below the melting point of the plastic.
Prototype tooling: Molds, dies, and other devices used to produce prototypes; sometimes referred to as bridge tooling or soft tooling.
Rapid tooling: In machining processes, the production of tools or tooling quickly by subtractive manufacturing methods, such as CNC milling, etc.
Selective layer sintering (SLS): Thermoplastic powder is spread by a roller over the surface of a build cylinder. The piston in the cylinder moves down one object-layer thickness to accommodate the new layer of powder. Here, a piston moves upward incrementally to supply a measured quantity of powder for each layer. A laser beam is then traced over the surface of this tightly compacted powder to selectively melt and bond it to form a layer of the object. The fabrication chamber is maintained at a temperature just below the melting point of the powder so that heat from the laser need only elevate the temperature slightly to cause sintering. The process is repeated until the entire object is fabricated. After the object is fully formed, the piston is raised to elevate it. Excess powder is brushed away and final manual finishing may be carried out.
Stereolithography (SL): Process used to produce parts from photopolymer materials in a liquid state using one or more lasers to selectively cure to a predetermined thickness and harden the material into shape layer upon layer. Once one layer is completely traced, it’s lowered a small distance into the vat, and a second layer is traced right on top of the first. The self-adhesive property of the material causes the layers to bond to one another and eventually form a complete, three-dimensional object after many such layers are formed. Stereolithography is the most widely used rapid-prototyping technology.
STL: A file format native to the stereolithography computer-aided drafting (CAD) software that is supported by many software packages; it is widely used for rapid prototyping and computer-aided manufacturing.
Subtractive manufacturing: making objects by removing of material (for example, milling, drilling, grinding, carving, etc.) from a bulk solid to leave a desired shape, as opposed to additive manufacturing.
Tool, tooling: A mold, die, or other device used in various manufacturing and fabricating processes such as plastic injection molding, thermoforming, blow molding, vacuum casting, die casting, sheet-metal stamping, hydroforming, forging, composite lay-up tools, machining and assembly fixtures, etc.
