PLA (Poly-Lactic Acid in full) is a thermoplastic which is extruded from the starch of plants, such as corn, cassava, sugarcane, cereals, or sugar beet. By being derived from biological resources this type of thermoplastic can be biodegradable under the right conditions (such as an active compost heap, with enough presence of oxygen) and therefore has a much lesser environmental impact than thermoplastics derived from fossil fuels.
This glow in the dark blue PLA has been packed full of glowing powder which enables a strong glow when fully energized. The filament does have a slightly rough texture to it and can also be slightly more brittle than normal PLA.
Tips & Tricks for printing with PLA
The printing temperature guideline for printing with our PLA filament is approximately 210°C. As each desktop 3D printer has its own unique characteristics, you might need to tweak around with your temperature settings a bit to get the best results. To obtain optimal results for your prints you need to take into account variables like your 3D printer’s nozzle diameter, your printing speed settings, and layer height.
PLA has much less tendency to warp compared to ABS. Therefore it can be printed both with and without a heated print bed. However, if your desktop 3D printer does have a heated print bed it is recommended to set your print bed temperature to approximately 40° to 50° C.
A good first layer adhesion is of the utmost importance in obtaining the best results for your prints. There are several tricks to get the first layer of your PLA print to stick better to the print bed of your 3D printer.
- Blue Masking Tape. PLA prints usually stick really well to blue masking tape. When preparing the print bed it is better to have tiny gaps between your strokes of masking tape, rather than having overlaps. Overlaps of smaller pieces of tape may cause difficulties later on during the print process.
- Coat your print bed with hairspray. Like ABS, PLA has a tendency to stick really well to extra strong hairsprays.
- Use polyimide tape (Kapton). PLA prints usually stick better to polyimide tape than to the print bed. When preparing the print bed it is better to have small gaps between your strokes of tape, rather than having overlaps. Overlaps of smaller pieces of tape may cause difficulties later on during the print process.
