Also printing them in PLA is a no go.Building Z Axis with SPECTRA longer ...

Dual wire gantry 3d printer
As I have come across excelent build by RichRap I have decided to build 3d printer described in his post at youmagine. Main goal was to build printer that will: be fastbe acuratebe huge :)As I have alredy build my first extruder now was the time to build printer frame. I have decided to go with 30x30mm aluminium extrusions and welded them together (as this is another new practice exercise for me). Using precision blocks and right angle the gantry was set and welded After checking all the angles frame ...

DIY metal extruder
This is my photo story showing the creation of my metal extruder from ground up excluding heating ceramic insert and stainless insert. clearing the face of the aluminium bar making cuts for the radiator Type caption for image (optional) taping filament hole for stainless insert Type caption for image (optional) After the radiator has been done i moved forward to brass nozzle. I've cut it from 25mm brass round stock. Nozzle is taped for stainless steel insert connecting it to aluminium radiator shown above. Nozzle has 0.35mm hole ...
