3D model description

Portable FDM Printer

I wanted to have a printer that can be transported easy without being damaged in transport.So I made this printer :-)
The housing is as small as possible while keeping standard print dimensions. This one can print 200x200x380mm. To keep it light, the housing is made from 9mm plywood. It is basically a square box with the printer mounted inside. So you can make your own housing or frame. Of course the housing is an advantage if you want to print ABS. Then I wanted this printer as fast as possible, because there’s not always much time, printing on site :-). Therefore I used a Bowden setup and a very light X and Y car. The vase printed in the picture is printed at 60mm/s in PLA. I want to test this printer with higher speed, but didn’t have time jet. The Red fan ducts on the side of the nozzle are not my own design.
Because my printers are very often connected to polluted mains (there are welding, milling and grinding machines nearby), there is a simple mains filter build in. This filter kills most of the EMF frequencies to the Arduino. The Atmel chip can do strange things under EMF stress. Normally I prefer a second ferrite coil but I didn’t have one. For the schematic please see the picture. Note that the capacitors need to be of an X2 and Y2 class so that if they die they are guaranteed not to short. C1 & C2 need to be of class X2. C3 & C4 need to be of class Y2. Also this filter needs to be in a metal case (see picture) and must be earthed always!

The controller is an Arduino and a Ramps 14 running on marlin. I included the marlin.ino in the Zip file.For information about configuring Marlin you could consult :

To hold the Teflon tubing in place, I used a gland nut. For some reason the original tube holders I have do not work very well.
If you have questions or do you think I forgot something, feel free to ask or comment :-)
