I've got the LittleRP solely for jewellery design and getting fine detail is an absolute priority!

As a novice, I'm very intrigued how you got this kind of resolution. What kind of projector are you using?

You say 45 micron X,Y, how is this calculated?

I'm using an Acer P1500 with a +4 closup lens.

Your help appreciated! :)


Well you'll be happy to know that we developed WaxCast on the LittleRP. :)

For all of these I'm running a 25um Z and 59um XY using an Acer X1240 @ 1024x768.

With my current setting, I'm not getting defined holes of a mm or less in diameter.

I believe the Z is correct but not sure about X and Y.

The calculations are on the forum that explain indepth how to measure and calculate microns for x,y etc. It has to do with the distance of your projector to the vat bottom, projector resolution...etc.

The LittleRP can print at superb detail as well! :)

Here are some pointers that may help:

Build plate needs to be parallel to the vat.
Light intensity - 30 micron Z - 45micron x,y
Insure adequate first burn in layers
Make supports thicker than you would for other resins.
Make sure you have a large enough initial surface layer.

Great print!

Been meaning to ask you, do you manage to get prints exactly to the size of your ring? Over here in the UK we go by letters. When I design my rings, I make them a default size "M" (not sure in states and elsewhere). But when I print, I get almost two sizes smaller!! Is this print shrinkage? It's quite a lot. Do you make any adjustments in CW?

No, the shrinkage might be 0.5% or so. If your print is that much smaller, it means you need to calibrate your print software. Do you use CW?

Yep :)

What do suggest I tweak in CW? Your help very much appreciated!
