In 2009, when our founder purchased one of the early MakerBot printers, he had a lot of the headaches that other users reported. Specifically, the hot ends were unreliable. So he bought a lathe, started making nozzles and helped other users fix their printers. His early hot ends were so successful that by 2010 he had built a 3D printer to go with his highly regarded hot ends, and MakerGear was making a name for itself in the rapidly growing 3D printing industry.
After several years of continuous improvement, the V4 hot end was released. The female thread on the interchangeable nozzles provides for short filament residence time (the longer the filament is at elevated temperature, the more it will break down into other plastics and cause jams), and the high temperature Teflon insert accommodates excellent retraction for highly detailed prints. The V4 hot end is available with brass or stainless steel nozzles in a variety of sizes, and several hardened steel aftermarket nozzles are available as well.
