3D Printing
3D printing builds parts layer by layer from PHA filament—ideal for prototyping, complex geometries, and small-batch production. Dry filament and controlled cooling typically drive print consistency.
Best forPrototypes, complex shapes, low volumes
Key controlsDry filament, extrusion temp, cooling
OutcomeFast iteration with minimal tooling
What is 3D printing (FFF/FDM)?
Filament-based printing feeds thermoplastic into a heated nozzle and deposits it in layers. Temperature, speed, cooling, and bed adhesion define print quality and mechanical performance.
Where is it used?
- Rapid prototyping and design validation
- Functional fixtures, jigs, and tooling aids
- Small-batch production and customization
What is PHA?
PHA (Polyhydroxyalkanoates) is a bio-based polymer produced through fermentation. It’s positioned as an alternative to conventional plastics and is valued for end-of-life options such as biodegradation and compostability, depending on grade and conditions.
How does PHA behave in 3D printing?
- Moisture sensitivity: dry filament reduces popping, stringing, and weak layers.
- Cooling balance: tune fan to maintain bonding while keeping details crisp.
- Temperature window: avoid overheating for stable flow and clean surfaces.
- Adhesion: tune bed surface/settings to prevent warping and corner lift.
Practical considerations
- Store filament sealed and dry; dry before critical prints.
- Start moderate on speed; tune retraction for clean travel moves.
- Use cooling as a fine control for bridging and overhangs.
- Consider application-driven blends for stiffness/impact/heat needs.
