Features
The Light Weight PLA consumables adopt special modification method and nano-foaming technology, which greatly improves the foaming multiplier of PLA material without affecting the printing effect of PLA material, and the foaming multiplier can reach more than 200%, with low shrinkage of printing molding, fine surface, strong adhesion between layers, smooth printing, no warping and cracking, etc.
Application
For customers with requirements on weight and density of printed models, e.g.: model airplanes, model boats.
Technical Specification
Filament Diameter: 1.75mm
Tolerance: ±0.03mm
Printing Temperature: 210 – 260℃
Heated Bed Temperature: 45 – 60°C
Printing Speed： 30~90mm/s
Shortcomings
Due to the nature of the foam,retract is largely ineffective, so the model will be more
stringing and will require later sanding.
