A group of Canadian inventors, (operating under the company name Rinnovated Design), have blown past their modest funding goal of $50,000 with the promise of a 3D printer, called the Peachy Printer, that costs $100. Since posting the project to Kickstarter Canada, the group has raised more than $350,000 in only four days.

According to the project’s leader, Yorkton, Saskatchewan resident Rylan Grayston, the aim of the project is to make 3D printing affordable enough for anyone. Similarly oriented hobbyist or pro-summer printers, like the 3DSystems Cube or MakerBot’s Replicator, typically retail for $1,300 or more.

The Peachy Printer’s low cost largely stems from its unique lithographic process. Instead of a printer head or extruder moved on the x and y axes by motors, the Peachy Printer uses laser light reflected by two electro-magnetically controlled mirrors. The directed laser light then solidifies layer after thin layer of photo-sensitive liquid polymer.

To control the z-height of the object, the printer uses a drip system to slowly raise the level of the polymer within a fish tank-like build space; as each build layer cures, the object being printed is submerged under the rising liquid and the process repeats. By the end of the build, the final print has been suspended in a tank of the uncured polymer that acts like support material and can be reused for the next print job.
