Hi Chuck,
It's probably not what you are looking for, because its best resolution is only 200 to 400 microns resolution, but would be worth considering the Up printer made in China ( ). We've now got 2 of them and are incredibly pleased with it.
In terms of print quality, it's not quite as good as our Dimension machine but considering the price difference, the parts are certainly usable. I haven't done any proper strength tests on the parts (but I will) but my overall impression is that the parts from the Up seem slightly stronger (and denser) than those from the Dimension.
It also prints up to 4 times faster than the Dimension.
The support material is also a bit harder to remove than on the parts from our dimension, as it uses the same ABS for the support material as for the part. But with a bit of practice (and tweaking the support material settings in the software) it's not too hard.
The biggest advantage with the Up, form our point of view, is the extremely low material cost. If we but the material from Cina it costs us around US$50/kg. But if we source our material locally (I just have it made by our local plastic welding supplies shop) it only costs us around US$25/Kg. So cheap that we can afford to let students print for free on it.

Hi everyone,

Happy New Year!

I'm looking for a low cost and easy to use RP machine for my personal use and very limited commercial use. Not looking to spend a lot of time with cleaning parts and want as close to "plug and play" as possible.

Looking at the VFlash and the uPrint, but can anyone offer some other suggestions? I know some cool stuff must have come out of Euromold.

Not So Rigid Requirements:

* $15k Budget
* Don't care about colors
* Easy postprocessing
* Cheap Material
* Good accuracy (100 microns)
* Small build area is ok
* Slow build time is ok

Objet Alaris is out of my budget range, but seemed like a great choice.

Thanks for the help!
