| New Polyurethane and MultiMaterial Thermosets for 3D Printing |
| The field of 3D printing is experiencing significant advancements with the introduction of soft, elastomeric materials. While thermoplastics dominate the current 3D printing landscape, this presentation highlights the innovative use of cross-linked polyurethane thermosets produced through reactive extrusion. Chromatic's soft polyurethane materials exhibit superior engineering and chemical robustness compared to other 3D printable soft polyurethanes available today. Utilizing traditional polymer chemical reactions, Chromatic's products align with commercial polyurethane polymers that have been in use for the past fifty years.
A key distinction is made between Chromatic's thermoset polyurethanes and VAT polyurethane materials, which use carbon-carbon acrylic backbone polymers for polymerization. Additionally, Chromatic's polyurethanes differ from thermoplastic polyurethane materials (TPU) used in FFF printing. Chromatic 3D Materials has commercialized a range of soft polyurethane materials, from Shore A 50 to Shore D 65, offering exceptional surface and physical properties. This presentation will explore the physical properties in the XY and Z axes, as well as chemical resistance and flame retardant (FR) properties.
The development pipeline includes polyurethane materials with electrostatic dissipative (ESD) properties, with early work to be reported. Furthermore, advancements in multi-material 3D printing technology will be discussed, encompassing multi-color and rigid-elastomeric materials. |
