After having transformed the world of computer desktop 3D printing with his original wood and stone filaments, German inventor Kai Parthy has teamed up with 3D printing device developer ReprapUniverse to turn it into a hotend capable-bodied of handling all of his specialty materials. On top of that, the 1730 Full Metal Hotend can handle both 1.75 mm and 3 mm filaments with the swift alter of a nozzle.
Combining their respective ten years of experience, Kai and ReprapUniverse have turn it intod the 1730 Full Metal Hotend to be as versatile as possible for FDM 3D printing. Uniquely, the component has a modular setup that combines a direct drive and bowden architecture, to allow for swift and effortless nozzle alters. Handling 1.75 mm and 3 mm filaments just requires swapping out nozzles, a system expected to take less than five minutes. And, for the reason the hotend is all metal, without any PEEK or PTFE tubing, it can reach higher temperatures to handle a wide variety of material types, of PLA and ABS to PU, PC and exotic filaments.
Other showcases include an optimized thermal barrier, wtihout the require for water cooling, a short heating zone inside the extra long nozzle for short heating times, reduced feeding friction for soft and brittle materials (such as flexible filaments), and shorter retraction times for improved speed. As a fully assembled component, the 1730 Full Metal Hotend has been created to fit a verity of 3D printing devices, with mounts and adapters created on the market for printing devices with the Greg’s Wade Extruder, Delta architectures, GRRF of German Reprap, and machines with a J-Head or E3D hotend.
From interviewing Kai, I learned that he does a lot of experimentation both at home and in local facilities, and frequently has his own equipment for creating new materials. He says in the 1730 Full Metal Hotend press release, “Over the last 5 years, I have created my own hotends for testing my filament designs. I in addition use and test with full metal Hotends on the market on the market but I frequently require to do extensive adjustments on them to overcome thermal issues. By this the yett came up to solve these thermal problems (PLA blockage etc..) in finding a new setup. Together with the team of ReprapUniverse we have created prototypes. Intensive testings and re-adjustments over the past months have resulted in fully functional prototypes that have that successfully passed the BETA phase. The 1730 has truly surpassed my first expectations. It has all the next on setting new standards as a consumer-friendly hotend.”
Of the yett that 3 mm filaments can go out of production in the next, Kai says, “This is nonsense. Special filaments that can not be generated in 1.75 mm diameter, soft filaments that in no way feed in a thin tube can always be manufactured in 3 mm diameter. The 3 mm filament market share yet holds of 35 % in Europe.”
The 1730 Full Metal Hotend sounds as yet it may be an yettl part for computer desktop FDM machines, once it is released. To bring it to market, Kai and RepRapUniverse can be hitting Kickstarter in mid-January, as that point, may all of your filament feeding prayers be answered.
Happy New Year!
Update 1/26/16: Welp, it’s mid-January and, as promised the 1730 Full Metal Hotend is now on Kickstarter, where Kai Parthy and RepRapUniverse are seeking a humble ~$16K to get this powerful hotend off the ground.
The hotend is created up of a heatsink, heatblock, filament nozzle(s), thermistor, axial fan, cartridge heater (12V or 24V), groove mount plate or round mount. These two mounting options, for the Greg’s Wade Extruder and for J-Head extruders, are shipped with each 1730 Full Metal Hotend, but additional mounting options can be generated in the next. Whilst the 44mm x 34mm hotend can just be able-bodied to reach 300 degrees Celsius at the moment, the team plans to release an tremendous module in the next that is capable-bodied of reaching up to 500 degrees.
With a shipping goal of March 2016, you will require to fork over $139 to get your hands on their new hotend, a decent price for the ability to 3D print a wide variety of materials in the two standard filament sizes. Given Parthy’s experience with extruding fancy filaments, I’d say that, when you do get your hands on the 1730 Full Metal Hotend, you will most likely be a quite pleased customer.
