Advanced Digital Design and Manufacturing (ADDFab): Platforms: UMass Amherst


Most popular plastic PA2200 (nylon-12) is our industry leading material, providing high resolution, strong and resilient parts. The material is white and can be dyed in 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 requires no support structures and allows you to print just about any geometry you can imagine. We print PA2200 on our EOS P110 printer. (Technical sheet)

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 sheet)

Multi-materials “Digital materials” are a mixture of UV-curable resins (acrylate chemistry) that can produce rigid or flexible parts, or somewhere in between. The base materials are called VeroWhite (rigid) and TangoBlack (soft). They can be combined in one part, and mixed to make shades of gray, or parts with combined rigid and flexible sections. We print digital documents on our Stratasys Objet Connex350. (Technical sheet)

Carbon fiber We have two options for super tough polymer parts with integrated carbon fiber. “Onyx” is nylon material with chopped carbon fiber mixed, and “Continuous Carbon Fiber” is nylon with carbon fiber yarn embedded inside. Both produce incredibly strong plastic parts. (Technical sheet)

    • Layer resolution: 0.100 mm

  • Stratasys Object Connex350

    The Objet Connex350 allows the creation of parts with several materials. Materials can be printed separately or in specified proportions, providing a range of mechanical properties. Parts can be any mix of rigid and flexible materials, creating prototypes with different hardness durometers, or even soft overlays on rigid materials.

    • Materials: several proprietary plastic and rubber materials
    • Build Volume: 342 x 342 x 200mm
    • 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 154mm

  • GCC LaserPro Spirit GLS

    The Spirit GLS offers fast 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: 36″ x 24″ x 7″
    • Thickness: up to 3/8″ acrylic

Advanced Digital Design and Manufacturing (ADDFab): Printing services, research and training in multiple advanced additive manufacturing technologies. For metal printing, the installation includes the EOS M290 for direct metal laser sintering and the Optomec LENS 450 for directed energy deposition. Materials include stainless steels, nickel alloys, cobalt-chromium alloys, and other experimental metal powders. For polymer printing, the setup includes an EOS P110 selective laser sinter printer (material: PA2200, nylon-12), a Stratasys Objet Connex350 material jet printer (VeroWhite, VeroClear, TangoBlack, UV-curable materials), a MarkForged Onyx One (nylon with chopped carbon fiber) and a MarkForged Mark Two (nylon with continuous strands of carbon fiber). Additionally, we have a media blaster, powder unpacking station, water blaster, and media cup for post-processing polymer parts. For software, we use Solidworks for 3D CAD modeling and Materialize Magics for STL manipulation and repair.

  • Training is available for every printer and tool in the lab. We also offer hands-on workshops for industry professionals and workforce development, in designing parts for additive manufacturing and operating laser-based 3D printers.

Fees approved by FY21 Specialized Service Center

Updated January 2021

the Advanced Digital Design and Manufacturing Lab (ADDFab) is available for use by academic institutions, industry and the local community.

ADDFab has three primary goals to serve this diverse customer base: (1) design and print large metal and polymer parts, (2) support academic research, and (3) provide training and education opportunities.

1. Design and print great parts

Two metal printers use fine metal powders to build parts as large as 25x25x30cm with details 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 that deposits metal lines and can produce parts from custom metal alloys.

Three polymer printers cover 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 details as fine as 250um. The main advantage of the SLS process is that it does not require support structures for cantilevered parts, which allows it to easily print extremely complex and delicate geometries. EOS-P110The Connex350 is a multi-material printer that can print soft and hard materials in one piece, and even mix materials to adjust material properties and colors. Markforged printers extrude nylon filament in a fused filament manufacturing (FFF) process and can print in nylon infused with chopped carbon fiber (Onyx), or incorporate a continuous strand of fiberglass, Kevlar or fiber of carbon in each layer.

For customers who need engineering or design assistance to get parts (or ideas!) ready for printing, we offer engineering consulting on an hourly basis with undergraduate students or experienced engineers. .

2. Support academic research

ADDFab facilities are available for use as a service where our staff does all the printing, but also for dedicated use on a daily or weekly basis. Training is available where students and faculty can learn how to use the equipment and then use it to conduct their own research into additive manufacturing.

We also provide printing services and technical support to professors of all university departments.

3. Training and education opportunities

ADDFab supports undergraduate and graduate courses in additive manufacturing by printing parts, offering tours, and training students in the use of equipment. We also actively collaborate with student groups and secondary schools.

For industry and the local community, ADDFab organizes a series of workshops on additive manufacturing. These aim to broaden the understanding of how 3D printing will affect the manufacturing industry and provide hands-on skills using industrial-grade 3D printing technology. Both types of courses are offered throughout the year.

If you have any questions about working with ADDFab on a future project, please contact us at [email protected] We look forward to working together!
