[KwartzLab] 3D printers: recommendations?

[doug moen]

Veloso's project is secretive, proprietary and overpriced.  LemonCurry and
B9Creator are open source, and seem more trustworthy.

How fast is Veloso's printer?  There's no information available. The most
he will say is that it depends on the material. There are videos of his
printer in operation, but time lapse photography is used to hide the
printing speed.

How much does resin cost? The most he will say is that he is hoping to make
resin available for < $150/litre. The open source projects give actual
prices and links to suppliers. Quotes range from $40-$100 per litre.

His design is not open source. He promised to make it open source at one
point, posted some documents, then yanked them off the web and went closed
source again.

His full kit costs $4000 on indiegogo, compared to $2375 for a full
B9Creator kit on kickstarter, and it's not clear what you get for the extra
money, since so much about this machine is hidden from view.
