About the 1730 Full Metal Hotend

The 1730 Full Metal Hotend came into existence by a unique cooperation between renown filament developer Kai Parthy and the team behind 3D-Printer Manufacturer ReprapUniverse (Achatz Industries). These two companies share more than 10 years of experience in the 3D-Printing Industry (3D-Printers & Filament), product design & development, sales and 30+ years of experience in electronics between them.

The 1730 Full Metal hotend is specially designed to provide answers to the limitations of current fused deposition modeling (FDM) Hotend technology. We are convinced that the 1730 Hotend will simply, improve and open new applications in 3D-Printing.

Story

For fused deposition modeling (FDM) 3D-printing 1.75 mm and 3 mm filaments are available. Some believe that 3 mm filaments will be discontinued in the near future. Kai Parthy’s (Filament developer & Hotend specialist) comments on this: “ This is nonsense. Special filaments which can not be produced in 1.75 mm diameter, soft filaments which hardly feed in a thin tube will always be manufactured in 3 mm diameter. The 3 mm filament market share still holds about 35 % in Europe.

Over the last 5 years I have developed my own Hotends for testing my filament creations. I also use and test with full metal Hotends available on the market but I often need to do extensive adjustments on them to overcome thermal issues. By this the idea came up to solve these thermal problems (PLA blockage, hotend leakages, etc..) in finding a new setup. Together with the team of ReprapUniverse we have build several different prototypes all over 2015. Intensive testings and re-adjustments have resulted in fully functional Full Metal Hotend. The 1730 has truly surpassed my initial expectations. It has all the potential on setting new standards as a consumer-friendly Hotend ”.

The 1730 Full Metal Hotend was successfully introduced and funded by a Kickstarter Campaign in January / February 2016. Shipping rewards to our backers started in late March 2016. The Kickstarter campaign allowed us to make the 1730 Full Metal Hotend ready for general sale at a much faster pace.
