This is our interpretation of the Mendel90 design by Nophead based around a laser cut frame. It borrows the fixing method from the Lasercut i3 design by Shane Graber and the majority of plastic parts are from the Dibond Mendel90.
A quick orientation around the printer:-
First, the laser cut frame is made from melamine-coated MDF which is much more resistant to knocks then regular MDF and doesn't require any painting or other finishing.
It is very quick to assemble with square nuts and M3 socket cap screws
The build area is 200x200x200mm
All the wiring comes ready to plug and play in pre-assembled cables or looms so there is no crimping or soldering required at all. The printer comes with a RAMPS controller with 5 "Ice Blue" Stepsticks and the Panelolu 2 controller as standard.
The acrylic enclosure is an optional extra which keeps the heat inside the printer to reduce warp when printing with ABS. It also helps to reduce noise and adds to the professional look of the printer. It uses the same fixing method as the printer frame and can be fixed on quickly and simply without disturbing the printer or calibration.
Overall, the design removes hassle from kit assembly at every turn. The printer can be easily put together in a day, with very little calibration required as all the critical dimensions are set by the laser cut frame.
Kits will be available shortly (Update: now available from our webstore). We have a couple of components to finish sourcing in bulk and I will do another blog post with a run-down of the assembly process. I also need to tidy up and document the source code for the plastic parts and frame. All the source will be available on our Github before the printer goes on sale.
We are supporting the RepRap stand at the TCT show this year and will have a Mendel90 LC or two on display. The TCT show is free to register for so please do come round and say hello.
