Prusament PLA Lipstick Red 1kg

PLA has a relatively low melting temperature of 175 degrees Celsius. Unlike so-called thermosets, PLA can be repeatedly heated above its melting temperature with very little material degradation. It is also a very hard but therefore brittle material and once it breaks, it often shatters.

Like any other material, PLA also has several weaknesses. A side effect of the low melting temperature is low heat resistance; prints start to lose mechanical strength at temperatures above 60 °C.

The combination of low UV resistance and low heat resistance means that PLA prints are not ideal for outdoor use. PLA is soluble only in chemicals such as chloroform or hot benzene. Therefore, it is better to use glue when joining multiple prints together.

Although PLA is a food-safe material upon contact with food, we do not recommend repeatedly drinking or eating from your 3D prints. Bacteria can multiply over time in small surface cracks that occur during printing. When finishing PLA surfaces, it is better to use wet sanding. Without water, friction can quickly heat the plastic, causing it to melt locally and making further sanding more difficult.
