The invention relates to a 3D printing method for the layer-by-layer fabrication of objects using laser transfer printing, and to a 3D printing device for carrying out the method. According to the method, a printing compound () applied to a carrier cylinder () is irradiated with a laser (), detached, and transferred to a base plate (). The resulting printing compound layers are subsequently cured and the process repeated until the object is completely built up. Using said claimed method, objects can be printed from a variety of possible printing materials with high throughput (over 1 kg/h) without affecting the print quality.

3D printing apparatus for layer-by-layer fabrication of objects using layer transfer printing

At least one silicone layer is applied to a substrate by a method employing laser transfer printing. The method is suitable for producing sensors, actuators and other EAP layer systems. The silicone layer in these systems may serve as an electrically conducting electrode layer or as a dielectric layer. The method may be configured to be continuous and may be combined with various other coating technologies.

Method for applying at least one silicone layer by laser transfer printing

In an additive 3D printing method for production of shaped articles from silicone elastomers, an elastomeric shaped body is built up step by step, by repeatedly precisely positioning portions of the crosslinkable silicone material and crosslinking by means of electromagnetic radiation. Charges that occur on the surface of the print material or on the article are neutralized by means of an ionization system.
