Photochromic PLA Colour change: White to Purple, 3mm, 1kg/spool

We want to bring you the most consistent and excellent filament possible and at a price that you can afford. We partnered with a company who custom make our plastic for us and have plastic engineers on site to ensure you get only the best quality filament.

What's more, each high quality roll comes on an easy turning plastic spool. We then have each roll vacuum sealed in an airtight plastic bag with a desiccant inside and finally packaged in a protective cardboard box so that your plastic is in the best possible condition and free of moisture when it gets to you. No one likes buying filament and discovering it's been soaking up moisture for a year in someone's warehouse.

Check out our conductive filaments, UV reactive filament, flexible filament, glass transparent filament and glow-in-the-dark specialty filaments. You'll love them.

PLA (Polylactic acid) is thermoplastic aliphatic polyester made of renewable resources like corn or starch. Its extrusion-temperature is much lower than ABS, and most often doesn't require a heated bed. It has the following characteristics:

1. Good toughness high strength, high stiffness

2. Good stickiness to the hot bed

3. Can be processed at 185c degrees but 210c seems to be ideal

4. Low shrinkage, thermoforming dimensional stability

5. Accurate diameter: 2.95(ideal for printers with a bowden cable)/1.75mm, variations + /-0.1mm,roundness +/-0.05mm;:

This filament changes color from White to Purple when exposed to UV Light. The color change occurs immediately. The color will change back to white when no longer exposed to UV Light.


Material: PLA

White to Purple
