Full Version: 3D Printed Overlay for DM42, DM41X ...
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Hello,

enclosed please find the source file (.skp for SketchUp) and the .stl data for an overlay for the DM4x hardware.

I have also attached photos. I have however rotated the enclosed 3d files after printing these specimens so that a new print will put the rougher side below and the smooth side up.

I have used the Swissmicros specifications for design:

I hope you find this useful.

Greetings,

Very nice! If one was able to switch filament colors mid-print, then legends should be possible.

Prusa i3 MK2.5S & MK3S/+ Multi Material 2S upgrade could do up to 5 colors...

Don't be afraid of editing .gcode files. If your slicer can show layer-by-layer, then you can figure out when to insert a pause to switch filaments mid-print.

I have a Prusa MK3S which after this weekend will be a MK3S+. I believe you can schedule manual filament changes in the slicer software without the Multi-Material upgrade.
I ran a quick test, see attached. The results could be improved by using a smaller nozzle than the 0.4 mm used here and perhaps PLA vs. PETG (used here) which is a little more stringy.

Almost to the point of 3D printed double shot keycaps! Things are looking up!
In addition to the ability to change colors at a specific layer, it is also possible to approximate double shot keys by using a color change mid-layer. Essentially, you print all of the key backgrounds, leaving letter-shaped holes. Then you pause, change filament, and continue the print, which then fills in the letter-shaped holes with the second color.

I have a video bookmarked somewhere showing the entire workflow for doing something like this, if anyone is interested.

I'm interested!

Merci, très instructif. / Thank you, very informative.

Whywould you have to switch mid print. Just do it in two passes.
It depends on how thick the print is, i.e. how many layers. If you go more than a couple layers between switching colors then the nozzle will drag on the outer layer.

Ideally you print layer 1 color 1, layer 1 color 2. Then layer 2 color 1 layer 2 color 2, then layer 3 color 1, layer 3 color 2. etc.

I want to replace the mainboard of mu printer with a dual extruder for dual colors.
Since this thread began I now do two prints, one over the other. The first one is one layer high, the second print is printed on top. See the photo.

looks very good
Hi Andreas,
I was more interested in your screen shot, cool offimg and chance of sharing.
Thanks
