Liquid Additive Manufacturing
Industrial 3D Printing: Functional Materials for Liquid Additive Manufacturing
DELO creates new opportunities for liquid additive manufacturing by providing functional liquid materials that are optimized for industrial 3D printing. The materials fulfil various functions such as transparency or flexibility and can be combined in one printing process. Another advantage: the printed components exhibit isotropic strength in all printing directions.
The liquid materials can be dispensed layer by layer at room temperature. After curing with UV light the materials are cross-linked duromers. Liquid Additive Manufacturing thus offers an alternative to 3D printing processes such as Fused Deposition Modelling (FDM), Stereolithography (SLA) or Material Jetting.
The components properties are comparable to those of high-performance plastics, like polyamide or PEEK. Therefore, they are well suited for automotive and microelectronic applications – especially for fine and functional structures.
