Re: First successful prints!

Cool! Do you have pictures of your printer as well? I'd love to see how you assembled your top-down vat and Z-axis.

Re: MiiCraft+ 3d Dlp resin printer, any experiences?

As an owner of one, I would heartily recommend the Kudo3D Titan 1 (http://www.kudo3d.com). It is a little more expensive, at $2999, but that includes the projector and a vat.

Plus, you can simply order it (and any additional things you want like resin or spare vats) directly off their website.

Re: Acer H6510BD

A few more questions, now that I'm understanding your method better.

What tools did you use to extend the holes by 3mm upwards? Is that lens assembly made of steel?

What size drill bit(s) did you use and did you have to use a drill press? Hand power drill?

Thanks!

Re: Acer H6510BD

No need to apologize for your English, I really appreciate you sharing your findings with us. However, I have one more question about the procedure you describe. When you say: I extend them upward for 3 mm. The top screw hole exploded. Then i reinstalled it. Do you mean that when you shift the lens ...

Re: Acer H6510BD

Today i moded my acer p1500 to solve upper border sharpness problem. I shifted my projector lens 3 mm down and the upper border sharper now. The projected image shifted down a bit. That sounds like a very interesting mod. Can you describe in more detail and perhaps show us some pictures of what it ...

Re: another one!

Nice work!

What are the printable dimensions for your vat? Your vat walls seem to be made of some type of sheet metal - did you design those yourself as well or do they come from another printer?

Re: Any resins strong enough for engineering purpose ?

I think the elongation that gives a part that "plastic" resiliency as opposed to glass-like breakage. Just comparing PLA and ABS, the general experience between those is that PLA is stiffer, but more brittle and overall more prone to breakage than ABS. That matches PLA's higher Tensile Str...

Re: Any resins strong enough for engineering purpose ?

Ooo.. SLS, that's sweet technology if you have sufficient space to deal with the powder cleanup. That machine seems to run Polyamide 12, which when used for SLS has the properties described at: https://www.solidconcepts.com/materials/sls-materials/ In particular, tensile strength of 6800 PSI and elo...

Re: Any resins strong enough for engineering purpose ?

In comparison to PLA, Natureworks 4043D (the most common US-sourced stock for PLA filament) has an Ultimate Tensile Stress of 7700 PSI and Elongation of 6%. That makes it 1.44 times "tougher" than Vorex by MadeSolid's methodology.
