The material decides how a print looks, how strong it is and whether it survives a hot car. Here is how we choose for jobs in Sydney.
| Material | Strengths | Watch out for | Typical uses |
|---|---|---|---|
| PLA, PLA Matte, Silk PLA | Huge colour range, crisp detail, low cost | Softens from around 55–60 °C | Gifts, figures, display pieces, indoor organisers |
| PETG | Tougher, slightly flexible, handles more heat | Glossier finish, fine detail a little softer | Brackets, containers, garden and kitchen-adjacent parts |
| TPU | Rubbery and flexible | Slower to print, limited colours | Bumpers, grips, seals, phone cases |
| ASA | UV-stable, heat-resistant | Needs an enclosed printer | Outdoor fittings, car and caravan parts |
| Resin | Very fine detail and smooth surfaces | More brittle, needs washing and curing | Miniatures, jewellery masters, small figurines |
The Australian summer test
A car interior in a Sydney summer can easily pass 60 °C. PLA dash mounts and phone holders can sag in that heat. For anything living in a car, on a balcony or by the pool, we use PETG or ASA. Indoors, PLA is fine and gives the best colours.
Finish options
- Matte hides layer lines and looks premium on gifts.
- Silk has a metallic sheen, popular for ornaments and vases.
- Multi-colour prints several colours in one piece; see how multi-colour works.

Common questions
Which material is strongest?
For everyday parts, PETG and ASA are tougher than PLA. For impact and flexibility, TPU. For very high strength we may suggest nylon or a bureau SLS print.
Is PLA biodegradable?
PLA is made from plant starch and is industrially compostable, but it does not break down quickly in a backyard bin or landfill.
