Re: my build!
Laying a projector on it's side like you have it may impact the way it cools the bulb or the electronics, which is why I say it may not like it you could overheat or you could be fine. I will force-cool my projector via a large hose and a 80mm fan (maybe 100mm) - really hope that I do not get in tr...

Re: my build!
Looks like a nice sturdy build. Your Projector might not like to sit on it's side like that unless that is not how it's being mounted? And I'm sure you know but just to be double sure, the printed parts are PLA? The resins do not like ABS at all, like I say sure you knew this but doesn't hurt to be...

my build!
Hey, Many thanks to all of you - helped me a lot to develop my machine. Designed fully in Solidworks and should be ready in a few weeks. # rails: 16mm and linear bearings # 16mm ball screw with 5mm pitch # 30x30mm aluminium rods # Acer H6510BD # Arduino board with stepper shield # 1:14 Nema 17 for t...

Re: no shrinkage resin!?
1.035^1/3 = 1.011533... Ok that means that 3,5% is VOLUME shrinkage not dimensional shrinkage! :D However: when printing e.g. a part with 200mm I think I will still not be able to print the first layer on the build platform directly as the shrinkage is too high: having the support material between ...

Re: Multiple monitors
a stacked configuration either vertically or horizontally for 2 monitors. -S During designing my machine I thought of a single projector version where the projector is on a slinding plate - this doubles the printing time but would just add a few more euros than to purchase a second projector. In ot...

no shrinkage resin!?
Hey,
I've designed a SLA Printer with a build plate of 240*135mm (1920 resolution *1,25):
If I would use a resin with even 1% shrinkage a part with e.g. 200mm dimension would shrink around 2mm!
...so: is there a resin with nearly zero shrinkage rate?

Re: hardware design questions
16mm rods seem to be overkill since your going to be adding a lot of weight IMO. I am using Delrin rollers with press fit bearings riding on a aluminum extrusion. You could also use what Tristram did and go with a 16mm linear guide and 5mm pitch acme screw. Definitely, but as I have a Nema 17 with ...

hardware design questions
Hi everybody! I'm currently on the way to design a rigid machine base and as I want everything perfect on my digital model I got some questions regarding dimension- I don't want to buy a projector before beeing sure that everything is as I want it to be. ;-) 1.) dimension On this site the focus of t...
