![]() ![]() And that’s if the incompatibility does not result in a failed print before it was finished. The result is that when printing with two incompatible materials like PLA and TPU, the completed print would be extremely fragile at the interface layer, causing them to break away from each other easily. In reality, some materials require extremely different printing temperatures and others are just chemically incompatible. In an ideal world, it would be possible to combine any two materials when printing a multi-material print and have them bond together just like two layers of the same material would. To understand how exciting this is, we need to talk about material compatibility in multi-material prints. The result is that a completed print that uses material interlocking will have a bond between the two materials that can withstand mechanical pressures which are only limited by the strength of the weakest of the two materials, and not the compatibility of those materials. It is achieved by generating an alternating overlapping pattern at the interface of two materials that physically ‘locks’ them together. This can be done on any printer capable of printing with two or more materials at once. This feature exists thanks to our beloved former colleague Tim Kuijper, who also introduced the Arachne variable line width engine! This great improvement for multi-material prints is based on research that resulted in him earning his PhD. With the introduction of material interlocking, it’s now possible to combine two completely incompatible materials and have them be fully bonded without any adhesives or fasteners required. When that happens, incredible new possibilities are created. We have another incredible UltiMaker Cura beta release ready for you! Cura users can look forward to improved print quality, an expanded and improved recommended print settings menu, and our biggest new feature since the Cura 5.0 release, multi-material interlocking!Īlso, as a cherry on top, this release includes a huge amount of new printer profiles for some of the most popular non-UltiMaker printers.Ĭombine previously incompatible materials with material interlockingĮvery now and again, something comes along that makes you rethink the fundamental rules of 3D printing.
