Natalie Mathis and Quincy Robinson, two 3D modelers and inventors based in Cincinnati, Ohio, have created a new 3D printer test kit "Graphica" featuring 12 Unreleased Test Chips focusing on Mechanical Components and Artistic Flair. The Graphica is designed for being printed on a FDM 3D Printer for measuring the abilities of your 3D Printer.

Each chip comes with printable (2D) instructions that details the tolerances found on the actually 3D File. Once the chips are printed, you can then gauge the success of the print by comparing it to the true sizes of the documented 3D file.

You might know Mathis and Robinson from their first Kickstarter with 3D Printer Test Chips launched in May this year and they raised $6,717, exceeding their $1500 goal by 450%.

The new Graphica are divided into 2 groups. Representational & Mechanical. Customers will receive 12 'Digital' Test Chips and a variety of printable displays that have been sized to fit snugly in most standard picture frame sizes.

The 'Representational' chips include:

  • 'Face' - Demos controlled smooth surfaces.
  • 'Insect' - Demos thin vertical surfaces & narrow undercuts.
  • 'Octo' - Demos flexibility.
  • 'Skull' - A taxing demo of narrow undercuts and detail retention.
  • 'Ghost' - Demos thin wall buildup and the ability to undercut thin structures. Designed to look cool with semi-translucent filament.
  • 'Tower' - Designed to be a Bridging Torture Test and the first step in successfully printing the 'Print & Play' test chips.

The Mechanical Chips are the first test chips of their type.

Each chip represents a movable feature that only has to be printed (with no supports) to work. We call this quality: "Print & Play". ...The idea is that once you have demoed a variety of 'Print & Play' techniques, you will be more capable of building and laying out your prints for even more 'Bang for the Buck'!

The Mechanical Chips include:

  • 'Spin' - Demos lengthy bridging and ability to print free-spinning structures on that bridge.
  • 'Scope' - Demos your printer's ability to print telescoping mechanism.
  • 'Chain' - Demos a chain sheet, disguised to look like a fish of sorts.
  • 'Gears' - Demos a 'Print & Play' gear train.
  • 'Shift' - Demos multiple swinging and shifting plates that dramatically increase the footprint of the test chip.
  • 'Mouth' - Demos a moving mouth with concealed control tab!

The Kit comes with a display that is sized to hold all chips and fit into a 5x7 inch frame. The price of the kit starts from $25. Find more info here on Kickstarter.

This kit is a waste of money. Doesn't take into account the different slicer programs that are used. Every slicer slices a little differently and can affect the way your print comes out and doesn't necessarily test the printer but the software.
