Hi, I’m looking to print a model via plaster or SLA. I have attached one of the files to this thread ( this is one of five that will come together to produce a sectional model as per the image attached),

as you can see the batons are quite thin. Are these strong enough to print? If not how wide would they need to be?

Thanks in advance

Really depends are you going to print the batons separate and then assemble or all together? All together your going to need a lot of support and risk the print failing. If you print the baton separated and the flat pieces you would end up with an over all cleaner model. Your current model you have loaded has a lot of floating pieces that with an FDM printer or resin the supports for it would be a project. A zcorp printer or a laser sinering one it wouldn’t be to bad but its very thin some of the slicing engines would reject it because of that. If you can keep your walls above .8mm that should be good and remember if you are having piece fit together .4mm is a very tight fit as most nozzles are around .35mm to .4mm and its good to base your wall thickness on nozzle size makes for cleaner slicing files and nicer prints. .8mm gives you two contour for you wall and is as thin as I would go in PLA and ABS unless you want a bit of flex. Hope that helps.

Thanks for your reply,

Ideally I would have liked to print as one piece and I was hoping that this would be possible with a zcorp machine. As for the floating elements in the stl files these are not an issue they are just left over elements from where i have chopped the section.

My primary concern is making this structure strong enough to print as one element. To do this do you think that 1mm batons would suffice?
