Production TPU seals on a modified FDM printer
Own product: intercooler seals for diesel engines
- Problem
- The seals needed soft TPU (Shore 65A), and standard FDM extruders jam on filament that soft at production volume.
- Approach
- Rebuilt a printer around a direct-drive flexible-filament path, a 32-bit board with TMC2209 drivers and reworked Marlin firmware.
- Impact
- ≈3,000 kits sold and 15,000+ components made, from design through production and sales.
