Roffelsen 3D PLA filament is a biosourced homopolymer obtained from corn starch and is biodegradable conform EN 13432 standards (temperature 58°C,
90% biodegradation within a maximum of 6 months).
Polylactic acid (PLA) is a natural alternative to polyethylene. Roffelsen 3D PLA filament is easy to print at low temperatures and is odorless. It provides a good surface quality, is somewhat glossy, and prints details with a high resolution. It has a low shrinkage and does not require the use of a heated build plate.
Overall, PLA is not as tough as more technical materials but does have a high tensile strength. It is not recommended for functional and mechanical parts. Items printed with PLA can lose their mechanical properties and may become brittle over time, because of the moisture sensitivity of the material. Temperature resistance of PLA is limited to approximately 60°C.
The PLA filament of Rofffelsen 3D can be used in industrial applications and also in domestic applications: creation of everyday objects, toys, prototypes and for use in modeling.
It offers the following features:
- Easy to print
- Low shrinkage
- Glossy finish
- Eligible to the EN 13432
- Available colors black, white and translucent. Other colors on request.
- Packaging: Vacuum sealed PS spools of 1000 g, 2300 g, 4500 g, 8000 g and 25 kg
- Minimum order quantity (MOQ) is 45 kg.

Proper material storage is key to good print results. An improperly stored material may become brittle, snap easier, and change colors. Alternatively, controlling the humidity is important for reliably printing materials that absorb moisture from the environment, like PLA.
To keep your filaments in optimal condition store them:
- in a re-sealable bag with the silica gel desiccant provided
- out of direct sunlight
- in a dry (low humidity) and cool location; optimal storage temperature for PLA is between -20 °C to +30 °C.
Incorrectly stored materials collect dust and absorb moisture. This leads to extrusion problems and loss of print quality. In addition, moisture absorption can cause popping sounds while printing.
To check the quality of PLA, try to snap the filament. If the PLA filament snaps easily, it is too brittle for use and should be replaced.
