A larger Ultimaker about the same size of a Makerbot but with 4 extruder mounts.

This is not by Ultimaker nut a design created using the origional Ultimaker design..


This has not be cut as of right now so do so at your own risk..

Cut this using 1/4" plywood (bought at the home improvement box stores in the US).

also cut the build platform form acrylic.

use most of the parts form an original Ultimaker with the exception of longer rods for the x axis.
(I do not have the exact diamention of the rods) and longer belts

This file was created using qcad. and the origional Ultimaker drawings.

Also I need to fix the Ultipanel mounting holes on the front..
If anybody has any suggestions and or changes I shall make them..

Note the Ultimaker only can be expanded to 2 extruder drives because of the electronics but there is room for expansion with this to 4 when there are electronics that can support 4.

Also I have changed the filament spool holders to the Makerbot Replicator ones.

No results.

I do not have a laser cutter. Could you provide the parts as printable PDF file so that I can print in paper, and use a dremel tool to mill the parts out of plywood?

where are the 4 mm parts???
