ADDFab Facility

Advanced Digital Design and Fabrication (ADDFab)

Located on the 4th floor in the Life Science Laboratories the Advanced Digital Design & Fabrication facility offers state-of-the-art 3-D printing and related digital manufacturing capabilities to support the translation of new technologies in biosensors and medical devices from lab bench to human testing that can then pave the way for commercialized innovative products and services. The core capabilities are metal 3-D printing, nylon 3-D printing (EOS Formiga P110), multiple material 3-D printing (Connex 350), laser cutting (GCC Spirit GLS). ADDFab provides 3-D printing and related digital manufacturing services to support device prototyping and testing as a perfect complement to the Device Characterization Core.

This equipment provides a complete array of the main capabilities for producing plastic parts and assemblies. The mission of ADDFab is to institutionalize the Center for Surgical Technology Innovation and commercialization in partnership with UMass Medical School.

This lab complements additional machine shops on campus. Services provided include facilities for researchers to perform 3D printing and related digital manufacturing supported by appropriate staffing, training for the future workforce in key skills needed for the emerging digital medical device industries, and developing and integrating new technologies in collaboration with industry and clinical partners that pave the way for commercialized innovations and economic development.

Additive manufacturing holds significant promise in the realm of personalized medical devices, models, and tools. The ADDFab is equipped with a range of manufacturing technologies, including Multi-material printers like the Connex 350 that allow for the creation of realistic soft tissue models that can be used for education, training and surgical preparation. Combined with medical imaging this technology allows rapid fabrication of models that are personalized to a patient, allowing a clinician a physical reference that they can use to plan a procedure.

Other processes supported in the ADDFab laboratory allow the creation of robust devices with applications in specialized medical tools, implants, and sensors crafted to a patient’s own anatomy. The ADDFab laboratory capabilities support a range of biocompatible metals, as well as strong and reinforced plastics useful for a variety of clinical applications.

  • Connex Objet 350 3D Printer

    The Object 350 allows the creation of parts with multiple materials. Materials can be printed separately or in specified ratios, offering a range of mechanical properties. Parts can be any blend of rigid and flexible materials, creating prototypes with different hardness durometers, or even soft overlays on rigid materials.

    • Materials: multiple proprietary plastic and rubber-like materials
    • Build Volume: 342 x 342 x 200 mm
    • Layer Resolution: 16 microns
    • Print Accuracy : 20—85 microns
  • EOS Formiga P110 3D Printer

    The Formiga P110 uses a laser to sinter a bed of plastic powder. The process facilitates the creation of batches of parts and allows complex geometries and quality builds from high strength plastic materials.

    • Materials: Polyamide or polystyrene
    • Build Volume: 200 mm x 250 mm x 330 mm
    • Layer Resolution: 0.06 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
  • Optomec LENS 450 Metal 3D Printer

    The LENS 450 operates by depositing controlled amounts of metal powder onto a work surface and sintering with a laser. The approach allows the machine to be used for part repair, hybrid manufacturing, as well as full additive part manufacturing.

    • Materials: Metals, including stainless steel, nickel, and others
    • Build Volume: 100 x 100 x 100 mm
    • Print Accuracy:  0.25mm position, 0.025mm linear resolution
  • EOS M290 Metal 3D Printer

    The M290 uses a laser to sinter a bed of metal powder, allowing layer by layer creation of geometrically complex, high quality metal parts. Using the M290 fully functional parts can be designed to be lighter, more complex, and better integrated into an assembly.

    • Materials: Metals, including stainless steel, nickel, and others
    • Build Volume: 250 x 250 x 325 mm
    • Laser: 100 micron focus diameter
  • 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

Notes:

  1. Prices are for trained users and do not include support staff, consumables, or materials.
  2. Printing-as-a-service is available on the P110 at $0.10/cm3 and on the Connex 350 at $14/hr, including materials.
  3. Support for untrained users and for additional help is $50/hr for technician, $117/hr for engineering or design.
  4. 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.
  5. 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).
  6. “Dedicated” means the machine is available for your exclusive use for that period of time. This includes setup, operation, and clean up.
  7. “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.
  8. Training Requirements:
  • All: EH&S Lab Safety Training, Fire Safety Training, machine specific training (from ADDFab)
  • Laser Cutter: Laser Safety Training
  • Metal Printers and EOS P110: Respirator fit and training
  • Metal Printers: Class C and D fire extinguisher training

  • The ADDFab and Device Characterization labs together provide the ability to design, control, and evaluate the 3D printing process specific to our requirements for developing the next generation of prosthetic components as well as embed smart sensing structures into the parts. Together the 2-axis Instron testing machine along with the Stress Photonics photoelastic strain measurement system enables the evaluation of new soft sensors we are creating to measure the physical contact between robots and people in collaborative work situations.

    —Frank C. Sup, Assistant Professor, Mechanical Engineering

  • The ADDFab Core has been a major help manufacturing and refining our hardware prototypes. The tools available there have dramatically decreased our turnaround for new designs, making it much easier to focus on our primary research without delays.
