Manufacturing
Formlabs Form3+ / Form3B+
The Form3+ and Form3B+ employ low force stereolithography additive manufacturing to produce high quality polymer parts. The Form3B+ is the medical line that can print with biocompatible materials.
Operated by MIRAGE and the Fischell Institute:
-
- 3x Form3+ printers with quick release platforms
- 1x Form3B+ printer
- 3x Form Wash automated wash stations
- 3x Form Cure automated cure stations
3D Systems ProX 200
The ProX 200 is a production grade metal printer that leverages direct metal laser sintering (DMLS).
Operated by Terrapin Works.
-
- Material: Ni-Alloy IN625
Creality CR6-SE
The CR6-SE is a consumer level fused deposition modeling (FDM) polymer printer. We use it to prototype, print jigs and guides for the rest of the lab.
Operated by MIRAGE.
Metrology
Hexagon Absolute Arm

Epson Perfection V39 II
High resolution 2D color scanner for measuring flat surface profiles (in contact with scanner glass) and surface patterns (e.g., text, color, roughness).
- Resolution: 5.3 µm (4800 dpi optical)
- Accuracy: ~10-30 µm
Photogrammetry – DSLR (professional)
High end photogrammetry setup allows us to take photos of parts from different orientations and create a 3D surface profile.
- Canon R7 DSLR camera
- AR400 ring flash
- Cross-polarization filters
- Automated rotation stage
Photogrammetry – Raspberry Pi
Budget photogrammetry setup enables the same capabilities as our professional setup with lower cost, lower accuracy, and lower resolution. Details still being measured.
