DLS Materials

Carbon Materials Cutting Edge

Carbon Materials are able to provide a broad range of applications from high-strength automotive materials to consumer product elastomers. Carbon Materials Objects of other additive manufacturing approaches are relying on their printing-direction. The final heating phase of the DLS-process solves this problem by initiating a chemical reaction inside of the semi-cured object that determines its technical properties. This process helps Carbon Materials and us to offer the best suitable Carbon Materials for the desired needs. Our printers and Carbon Materials manufacture objects with high resolution and engineering-grade mechanical properties. Be one of the pioneers to access cutting-edge Carbon Materials with PLG Global.
