The IMPEE Rapid Manufacturing Design Studio (RMDS) focuses on a broader way of designing rather than a specific field or niche within design. The RMDS is geared to stimulate creativity and importantly it enables the physical realisation from scientific principles. The RPDS is located in the James Naysmith workshop and comprises the following rapid prototyping machines:

(1) Fused Deposition Modelling (FDM) machine, Fortus 400MC

The Fortus 400mc allows manufacture of multiple production-grade thermoplastics in-house for conceptual models, functional prototypes, manufacturing tools, and end-use parts. Only the ULTEM* 9085 (high temperature) and PC-ABS (bio compatible) blend is currently available in RMDS.

Systems specifications:
Build Envelope (XYZ) – 406 x 355 x 406 mm
Layer thicknesses: 0.330 mm – 0.127 mm
Achievable accuracy: Parts are produced within an accuracy of ± .127 mm (± .005 in.) or ± .0015 mm/mm (± .0015 in/in), whichever is greater. (Accuracy is geometry dependent. Achievable accuracy specification derived from statistical data at 95% dimensional yield.)

Material specification:

  • ULTEM 9085 offers a well-vetted high-performance thermoplastic. Advanced applications include functional testing, manufacturing tooling and direct digital manufacturing of end-use parts — including aircraft interior components and ductwork. This high-performance FDM thermoplastic expands the use of additive manufacturing into applications that demand thermal and chemical resistance. ULTEM 9085 works with breakaway support material and is available in tan at the RMDS. (See more at: http://www.stratasys.com/materials/fdm/ultem-9085#sthash.OaDDUJ7D.dpuf)
  • PC-ISO is the strongest, most heat-resistant biocompatible material available with FDM technology. It is gamma and EtO sterilizable and complies with ISO 10993 and USP Class IV. (See more at: http://www.stratasys.com/materials/fdm/pc-iso#sthash.SyblYCKa.dpuf)

(2) Multi-material polyjet CONNEX 500 3D printer

The Objet500 Connex offers multi-material 3D printing in a build envelope to support large models or many parts.
