When outputting a string or raft of say S1 chairs, you recomend craeting a rectanglular shape in purple or mauve (cant remember which) that will act as a printing base on the build plate.
Would it be possible to have a whole in either end of the raft, to act as a suspension point for use in a washing and or curing station?
I dont have an elegoo mercury yet but hope to get one the next time there is an offer.
I believe you have mentioned propping the strip on a glass beaker inside the mercury for curing?
The colour of the rectangle doesn't matter. Any rectangle shape found in the background shapes is treated as a raft when exporting for 3D printing the chairs. Likewise any line shapes found in the background shapes are treated as splints when exporting for 3D printing a timbering brick.
It would be possible to put a hole in the raft (anything is possible ), but not very easily with the current code. I would need to write something new for creating the support rafts.
But I don't think a hole is needed -- certainly it didn't occur to me that one was needed when I made the chairs. If you are using the Elegoo wash/cure station, the rafts remain on the build plate while being washed. A bracket is supplied to suspend the build plate in the wash tub.
Likewise when brush washing the fine detail over a suitable container, the rafts can remain on the build plate:
After washing and blasting dry with an air gun/hairdryer, the rafts are peeled from the build plate ready for curing. Yes, because the chair rafts are so small in relation to the size of the wash/cure station, I placed them on an upturned glass jar on the turntable for curing. That puts them more central within the UV beam, but whether it made the slightest difference I have no way of knowing. I gave them a couple of minutes each way up on the jar. Different coloured resins take different times to cure because the UV needs to penetrate the translucent resin. But the chairs are so small that they seem to need only a couple of minutes. It is being translucent which makes them so difficult to photograph.
Curing continues in UV light until they eventually crumble to dust 5 years later. So keep them in the dark until you need them, paint them as soon as you have used them, and draw the curtains in the railway room when the sun is shining.
