Hello Fellow Formers,
I read a post recently, about the need to drain the resin out of the build platform when switching to another color, especially from black to white. It seems that with long prints the resin soaks into the build platform, which leaks out of it during the course of the print. A solution would be to purchase a separate build platform per color, but since I don’t have the room to keep them and I don’t like to spend more money than needed, I came up with another solution; a build platform funnel!
I started sketching in Rhino, which I love by the way, and after a few hours of tweaking and tinkering I came up with this design:
It consist of two parts, the upper funnel part and the foot with a drain hole and some support. Here is a picture of the funnel:
I used half spherical shapes to lift the sides of the build platform of of the sides of the funnel, in order to let the resin leak out of the build platform.
The foot is actually just a round disc with a hole in it to accommodate the funnel at one side and to be used as a lid on the plastic cups I often use:
The lower side of the foot is strengthened with four small supports:
For the funnel part I used the following orientation and support in PreForm:
… and for the foot, this orientation and support:
Just as a previous project of mine (the [resin tank comb][1]), I would like to share this one as well. So here is the list of files that are open for download, sharing and building;
First, here is the STL file of the funnel part of the build platform funnel:
Second, here is the FORM file of the funnel part of the build platform funnel, for quick and easy printing:
Third, here is the STL file of the foot of the build platform funnel:
Fourth and finally, here is the FORM file of the foot of the build platform funnel, for quick and easy printing:
I haven’t had the opportunity to print both items, since I have some problems with my Form 1+. I guess the mirrors need cleaning, so I opened a support ticket to resolve it. As soon as I finished my own Build Platform Funnel, I’ll post some pictures here.
In the meanwhile you all could give it a try, don’t wait for my build. I hope you enjoy this project and I would love to see some builds here…
Kind regards,
Jolmer
