Standing Controller box, warping issues

A project log for Building the Thor robot

Building a 6-axis robot based on the Thor robot. When size DOES matter!

This weekend I finalize the Standing Controller box 3D printing from Danny. I love the design and he demonstrated a lot of creativity. This print took 13h26 min.

But my 3D printer and ABS plastic had a lot of warping issues.I will look out for other ABS plastic that may have less warping issues. Or maybe next time I just use PLA instead.

It started like it would print normally. I took special precautious to make it was extra sticky to the heat bed by pouring a bit of acetone on it and then scrub it with leftover ABS. That plastic melted on the heat-bed and created a better sticking layer.

The first 5 mm went perfect with solid sticking on the bed. But as the print grew it actually started to pull the plastic from the heat-bed. And the fact that I also have splits in the layers in between means that I probably need a temperature controlled enclosure.

I can also repair the holes with some pasture or ABS hiding.

Top view with the Ultratronic v1.0 pro board inserted to see if it did fit. It appears that the box will be just right.

Partially assembled with the parts I printed last week. Missing in this view are these cool strips that can be colored differently and then inserted into the groves.

The lid on the right, I printed yesterday and was a 7 hour job. It also had warping issues.

I am wondering if the box will be better upside down. I probably want to blow the heat outside the box. But in that case the ventilator needs to be at the top.

I think I will have to get some nice paint to color Thor soon.
