3D printing research team

PrintMathLab Team

We are a team based in Singapore and Hong Kong, dedicated to researching 3D printing.

Our site explores FDM printing through dimensional tolerances, extrusion, calibration, materials and print cost. We publish calculators and guides that show their assumptions and calculations.

Research and measurements

Our guides distinguish calculations and published references from first-hand measurements. Until a bench test has been completed, the guide shows a “Field test pending” box describing the planned test instead of results; see the first-hand bench testing policy.
