| Factory Advantage | Handling the low melt viscosity of HIPS for microfluidic applications is a delicate balance. While it's excellent for filling intricate channels, it often leads to stringing and nozzle drool on less stable machines. Our approach leverages the superior repeatability of the Haitian Mars III 90T's servo-hydraulic system. This allows us to maintain exceptionally stable melt pressure and precise nozzle control, transforming the material's low viscosity from a liability into an asset for net-shape feature replication. By combining this machine stability with our strict, audited pre-drying protocols to eliminate silver streaks, MechanoFab consistently produces optically clear, defect-free precision consumables. This single-step molding process, performed in our ISO 14644 certified cleanroom, ensures dimensional integrity and compliance with ISO 13485, eliminating any need for secondary operations that risk channel collapse or contamination. |
