Experimenting With Lasers! by Jason Wu

Posted on September 17, 2017

We are extremely happy to announce that the final Polyfuge iterations for our Kickstarter backers will be laser-cut! Laser-cutting allows us to produce units faster while also adding interesting material options like plywood and acrylic.

The frame of our Polyfuge Kickstarter prototype consisted of 3D-printed panels fastened with nuts and bolts. While the interlocking panel aspect of the design was successful, the 3D-printed panels experienced louder spin noise and more vibrations due to infill.

As a result, we have decided to switch to laser-cuttable materials such as plywood and acrylic. In addition to aesthetics, the new material choices are favorable in that they are stronger and more effective in dampening the vibrations caused by the rotor.

We are offering a variety of colors for our acrylic material option (red, blue, black, white, and clear). All Polyfuge units will be shipped with clear acrylic lids in order to make the rotor visible during centrifugation.

While we are upgrading to laser-cutting for our kits, we will still be releasing 3D-printable STL files when we release the Polyfuge hardware/software documents open-source in May, 2018. This means that if you don't have access to a laser-cutter, you will still be able to 3D-print the frame components.
