After years of work, [Junior Veloso] is finally getting his 3D printer project out to the public. Unlike the Makerbots and repraps we usually see, [Junior]‘s printer uses light-curing resin and a DLP projector to build objects with incredibly fine detail.
One highlight of [Junior]‘s project is the development of low-cost resins. Normally, light curing resins are extremely expensive, but [Junior] is actively trying to get the price of resin down to $150 USD per kilogram. A quick back-of-the-wolfram calculation tells us you should be able to print about 7-800 cubic centimeters with a kilogram of resin. It’s much more expensive than plastic filament used in other 3D printers, but that’s the price you pay for quality.
There’s a very popular Indiegogo campaign that is trying to raise money to mass produce the resin and some components of this kit. We’re not impressed with the rewards for this campaign – $59 for a .PDF description of the printer without any dimensions, $159 for a BOM, dimensions and the formula to make your own resin, and $400 for the closed-source software [Junior] devleoped – but hopefully this Indiegogo gets cheap resin out onto the market. There’s a short FAQ about this printer, so we’ll leave our readers to tactfully discuss the merits of this printer in the comments below.
