RepRap Mendel Prusa vs SLA-7000 Stereolithography. David against Goliath....

We have made a simple comparison between SLA and RepRap Technology. You can find the results in our blog:

What size are those yodas printed at 100% 50% etc. I would love to show what a well tuned RepRap can do.

These were printed 6months ago and are still improving. 0.16mm - 0.10mm

This one is 50micron on Tantillus.

Both yodas were printed at 100%.

The 50 micron yoda printed in your Tantillus is really impressive!

It's not possible to see any detail in the white Yoda to make a meaningful comparison.

Is the problem of white...

Spray them both in grey primer - it'll bring out the details.

It may be worth noting that the SLA7000 is over a decade old now - it's by no means the best SLA can achieve. 500,000€ buys you a helluva system these days - a production grade iPro machine, or a few Projet 6000/7000HD's - both of which easily best the old SLA7000 systems.

I'm not meaning to downplay just how far RepRap has come, the results are certainly very impressive for such an affordable system.

Very impressive.

I can see the detail in the white mostly. I think the lines show up more clearly with FDM as the edges are not so square from layer to layer. The have a rounded profile and it makes each layer much more distinct for the same thickness. Also they are not so perfectly accurate and any that don't line up exactly contribute to the visual lower quality.

A comparative material strength test would also be interesting.

Make your Mendel twice as accurate.
