Note: D3D Sigma Prototyping ABS Spool and Spooless are made of different material.
1kg (2.2lbs) spool of D3D Sigma is ABS filament Vacuum Sealed with a desiccant pack.
ABS D3D Sigma is another version of D3D Filaments Series. The Sigma has more MattE Finish and it is made for everyday use and prototyping.

Material: 100% Grade ABS
-
Property: Non-Brittle Formula Blend

Manufacturing Process: Controlled using Non-Contact Laser Diameter Gauge:±0.03 mm Tolerance. Monitored with rapid, reproducible and repeatable measurements to exact dimensional tolerances. Maintaining high consistency of dimensional accuracy, the production process embedded with Error Proofing Mechanism (POKE-YOKE) that automatically stop a production line the moment a non-conforming measurement is detected.
- Great for Aceton Smoothing Process
