I'm a Stanford PhD researcher looking for an experienced engineer, product designer, or 3D printing specialist to take ownership of a turnkey design-to-delivery project involving custom high-precision sample holders for micro-CT scanning of geological samples.
We already have initial CAD/STL designs and are looking for someone who can refine the engineering, manufacture prototypes, test functionality, and deliver finished, working parts.
Project specifications:
Approximately 387 mm long, with 35 sample compartments
Four versions: 5, 6, 7.5, and 9 mm diameters
Thin walls (approximately 0.6–0.9 mm)
Precision sliding lids with small locking features
High-resolution resin printing (SLA/DLP or another suitable process)
Materials suitable for micro-CT imaging, ideally with low and uniform X-ray attenuation
Scope of work:
Review existing CAD/STL files for manufacturability.
Improve the design, tolerances, sliding mechanisms, and structural stability where necessary.
Recommend appropriate printing technology and materials.
Produce initial prototypes and test mechanical fit and functionality.
Iterate until the design meets agreed functional requirements.
Manufacture and deliver the final holders, along with updated CAD/STL files.
What I'm looking for:
Someone experienced with precision 3D printing, mechanical design, and prototype development who can manage the entire process from engineering through final fabrication and delivery, including coordinating with external printing facilities if needed.
Prior experience with SLA printing, tight-tolerance components, or scientific instrumentation is a plus.
Existing designs and reference files:
