Material Guide: Which Material for 3D Letters?
For decorative indoor 3D letters, PLA is the best choice: high quality, dimensionally stable and very smooth. For lasting outdoor use, weather-resistant plastics like PETG or ASA are intended. The currently available material is shown live in the configurator.
PLA – ideal for indoors
PLA is made from plant-based raw materials, is dimensionally stable and gives a very smooth, clean surface. It's perfect for wall decor, name signs and light indoor decoration. Heat resistance is around 55 °C, so avoid direct sun behind glass or a hot car.
We currently produce all letters in PLA.
PETG, ABS & ASA – for stress and outdoors
PETG is more robust (up to ~80 °C), suited to signage and stressed parts. ABS is especially tough for technical uses. ASA is UV- and weather-resistant (up to ~95 °C), the choice for lasting outdoor use. These materials are planned in our range – orderable options appear in the configurator.
Which material for what?
Indoor decor, names, gifts: PLA. Signage with some stress: PETG. Lasting outdoor use, weatherproof signs: ASA. If unsure, our support helps you choose.
Frequently asked questions
Which material is best for outdoors?
For lasting outdoor use, ASA is best as it is UV- and weather-resistant. PLA is designed for indoors. Available materials are shown in the configurator.
Is PLA weatherproof?
PLA is intended for indoors and only limitedly UV/heat resistant (to ~55 °C). For outdoors we recommend weatherproof materials.
Which material is currently available?
We currently print in PLA. Further materials like PETG, ABS and ASA are planned – orderable options are shown live in the configurator.
