strong and accurate plastic and metal parts
3D Printing Services
Choose from a variety of strong and flexible plastic materials, color options, and metal alloys. Typical delivery in less than one week for plastic parts and less than two weeks for metal parts. Email email@example.com to learn more. See details on materials and equipment below.
Workshops & Training
We offer hands-on workshops for both our polymer and metal printers. Participants spend one to three days on the complete process, from part preparation in software, to printer setup, to printer cleanup and post processing. Everyone goes home with real parts that they made! Classes are no larger than three students, and scheduled when it’s convenient for you. Contact firstname.lastname@example.org to sign up.
We can help
We can help print your most complicated, advanced geometries, in all different materials. We also can help you experiment with new materials, new metal alloys, and new laser sintering strategies.
Most Popular Plastic PA2200 (nylon-12) is our workhorse material, delivering high resolution, strong, and resilient parts. The material is white and can be dyed a variety of colors (red, blue, green, orange, yellow, pink, and black). The best part about this material is that it works with the selective laser sintering (SLS) process, which does not require support structures and allows you to print just about any geometry you can imagine. We print PA2200 on our EOS P110 printer. (Technical datasheet)
Most Popular Metal “15-5” Stainless Steel is our most popular metal material - an iron alloy with 15% chromium and 5% nickel. It is a corrosion resistant stainless steel that can be polished to a mirror finish and heat treated to increase its strength and hardness. We print 15-5 on our EOS M290 printer. (Technical datasheet)
Multi-material “Digital Materials” are a blend of UV curable resins (acrylate chemistry) that can produce parts that are rigid or flexible, or somewhere in-between. The base materials are called VeroWhite (rigid) and TangoBlack (flexible). They can be combined in the same part, and blended to make shades of gray, or parts with rigid and flexible sections combined. We print Digital Materials on our Stratasys Objet Connex350. (Technical datasheet)
Carbon Fiber We have two options for super-strong polymer parts with embedded carbon fiber. “Onyx” is a nylon material with chopped carbon fiber mixed in, and “Continuous Carbon Fiber” is nylon with an a carbon fiber thread embedded inside. Both produce incredibly strong plastic parts. (Technical datasheet)

- Layer Resolution: 16 microns
- Print Accuracy : 20—85 microns
Markforged Mark Two Printer
The Mark Two printer switches between two nozzles to create carbon fiber, Kevlar, or fiberglass. The resulting parts have high strength to weight ratios that can be used for tooling, fixtures, and prototyping.
- Materials: Nylon with carbon fiber, Kevlar, fiberglass
- Build Volume: 320 x 132 x 154 mm
GCC LaserPro Spirit GLS
The Spirit GLS allows rapid laser cutting and 256-level grayscale engraving. In addition to cutting potentially complex geometries in materials like wood and acrylic, it can engrave aluminum.
- Materials: Cuts acrylic and wood; engraves aluminum
- Build Volume: 40” x 24” x 7”
- Thickness: Up to ¾” Acrylic

|FY21 Specialized Service Center Approved Fees|
- Prices are for trained users and do not include support staff, consumables, or materials.
- Printing-as-a-service is available on the P110 at $0.10/cm3 and on the Connex 350 at $14/hr, including materials.
- Support for untrained users and for additional help is $50/hr for technician, $117/hr for engineering or design.
- Shared rates shown are “per simultaneous user”, so a lab could have multiple trained users and pay one shared fee, as long as only one piece of equipment is used at a time.
- All rates are for academic research for UMass (all) or the Five Colleges. Personal and industry use rates are 50% higher (e.g. $300 → $450).
- “Dedicated” means the machine is available for your exclusive use for that period of time. This includes setup, operation, and clean up.
- “Shared” means that the machine is available on a first-come, first-served basis. There is no guarantee that shared equipment will be available at any specific time, and priority will be given to those who schedule dedicated access.
- Training Requirements:
- All: EH&S Lab Safety Training, Fire Safety Training, machine specific training (from ADDFab)
- Laser Cutter: Laser Safety Training

Printing with Us
Printing and cutting services are available by the hour and include full technician support, or limited support for trained individuals. For details contact Dave Follette at email@example.com.
The Advanced Digital Design and Fabrication Lab (ADDFab) is available for use by academic institutions, industry, and the local community.
ADDFab has an array of cutting-edge, industrial-grade, 3D printers.
ADDFab has three primary goals in serving this diverse customer base: (1) Engineer and print great parts in metals and polymers, (2) support academic research, and (3) provide training and educational opportunities.
1. Engineer and Print Great Parts
Two metal printers utilize fine metal powders to build parts as large as 25x25x30cm with detail as fine as 250um. The EOS M290 is a powder bed system that uses direct metal laser sintering (DMLS) to build parts layer by layer while the LENS 450 is a directed energy deposition (DED) system which deposits lines of metal and can produce parts from custom metal alloys.
Three polymer printers span three different printing technologies. The EOS P110 is a powder bed nylon printer that uses selective laser sintering (SLS) to produce parts. It has a build area of 23x20x30cm and can produce detail as fine as 250um. The primary advantage of the SLS process is that it does not require support structures for overhanging parts, so it can print extremely complex and delicate geometries with ease. The Connex350 is a multi-material printer that can print both flexible and rigid materials in one part, and even mix the materials to adjust material properties and colors. The Markforged printers extrude nylon filament in a fused filament fabrication (FFF) process and can print in nylon infused with chopped carbon fiber (Onyx), or embed a continuous strand of fiberglass, Kevlar, or carbon fiber into each layer.
For customers who need engineering or design support to get parts (or ideas!) ready for printing, we offer engineering consulting on an hourly basis with either undergraduate students or experienced engineers.
2. Support Academic Research
The ADDFab facilities are available for use as-a-service where our staff does all of the printing, but also for dedicated use on a daily or weekly basis. Training is available where students and faculty can learn to use the equipment and then use it to conduct their own research on additive manufacturing.
We also provide printing services and engineering support for faculty in all academic departments.
3. Training and Educational Opportunities
ADDFab supports undergraduate and graduate courses in additive manufacturing by printing parts, providing tours, and training students on how to use the equipment. We are actively partnering with student groups and secondary schools as well.
For industry and the local community, ADDFab hosts a series of workshops on additive manufacturing. These are intended to broaden the understanding of how 3D printing will affect the manufacturing industry and to provide hands-on skills using industrial-grade 3D printing technology. Both types of courses are offered throughout the year.
If you have questions regarding how to work with ADDFab on a future project, please contact us at firstname.lastname@example.org. We look forward to working together!
