Build Your Own SLA/SLS

Hey,

i've tested a little bit and now i've got a solution for resin floating.

The resin and the solution stays stable for 3 weeks now and there are any reactions.


I've got no problems until now and i was able to save nearly 150$ for resin.


If there is somebody interested in getting this stuff, write me message.

regards,

how does the water affect the stability of the resin while printing? I would imagine the resin sloshes around more on top of the water? like if you were to bump the table in the middle of printing a layer would it affect the layer thickness due to the resin moving from waves or ripples in the water?

I am very interested. I'm about to start a build and would like to do top down. Thanks!

I'm also interested , would share the recipe of your mixture ?

According to Josh at MakerJuice their resin has a density of 1.1g per cubic meter or 1.1 g/m3. Water has a density of 1g/m3 how ever salt saturated water or brine has a density of 1.2g/m3. Glycerine is also in that range with 1.26g/m3. Hope this helps, if I can figure it out I should have a sample machine built by the end of April. This method would also have to address the vertical deviation from the platform and projector staying still and the surface of the resin moving.

Not sure if this is the correct place for this question but seeing the subject title is "top down with resin" I figured it would be the best place to ask.

Question: With top down set-ups, is it possible to simply pour the unused portions of resin back into its container until the next time you need to print something? Or is resin no good once it is in the VAT? Seems like one of the main disadvantages with top down is the amount of resin required to print something.

Use a vat that doesn't allow any light in, and has a lid. No need to remove the resin from the vat between prints then.

Assuming that the VAT is free of light on from sides how long would resin be good for once it is poured out of the original container?

Im thinking of trying out a top down with floating resin for my LCD printer.

Im just having too many issues with cured resin sticking to the vat on bottom up. I have a very large build area (400x300x300) and when printing large parts the sticking becomes very bad, I originally tried to stay away from top down because I would need a crazy amount of resin to fill my vat, but with this floating resin I think it wouldnt be so bad and it would solve my sticking issue.

Im going to try experimenting, If anyone has experience with it please let me know if you found anything helpful.
