Filaments
PLA or PETG: which filament to choose
Both materials are 1.75 mm, made in-house, with laboratory control of every batch. The difference is in tasks, temperatures and colours.

How to prepare a material selection request
We start from the function of the part and the equipment: we choose a ready-made grade or draw up a brief for a formulation, check the process and confirm the result with measurable criteria. The fuller the request, the faster the technical answer.
What to include in the request
- Printer and process — the printing technology and the equipment model.
- Function of the part — what the part does and what loads it bears.
- Current material — what you print with now.
- Problem — what does not suit you in the current solution.
- Temperature and environment — operating temperature, chemicals, moisture, ultraviolet.
- Acceptance criterion — the property by which a part is considered good.
- Planned volume — a pilot batch or a series.
- Country of use — the documentation requirements depend on it.
What happens next
Before a pilot batch starts we agree on four things:
- we agree the format: granules, a test processing run or qualified filament;
- we fix the equipment, sample geometry, settings and measurable acceptance criteria;
- after testing we draw up conclusions, corrective actions and scale-up conditions;
- we check the current revision of the technical data sheet, safety data sheet and certificate of analysis.
Three ways of working
Ready-made material — selecting a resin, granules or filament for your equipment and task. Contract manufacturing — granules, local filament extrusion, production under the partner’s brand and a joint print regime. Custom development — formulation, pilot batch, testing and transition to serial volume.
