Printing your own designs using the MOD-t can be an exhilarating experience. Seeing something you’ve created appear layer by layer is very rewarding, but it’s only possible if your design’s size, angles, and orientation are compatible with the MOD-t.

Here are some aspects of design that could greatly affect the overall “printability” of your work.

1) Size

Part of what makes the MOD-t great for homes, schools, and businesses is its lightweight, compact size. Designers should take heed of this space-saving design when sizing their models. The overall MOD-t printing envelope is 150mm x 100mm x 125 mm. You can set your file-viewing program to these specifications to test your design sizing before sending your .stl or .obj file to print. (Get our Cura profile information and learn more about using Cura with the MOD-t in this How-To blog post.)

2) Angles

Overhangs, bridges, and other tricky angles can greatly affect print success. The MOD-t can handle angles, but when angles become too severe, the quality of your print will suffer. The MOD-t handles angles up to 45 degrees with ease and can still successfully print parts with angles of up to 60 degrees. Including angles any steeper than 60 degrees could be detrimental to your print, but you can add removable supports to help stabilize your print.

The Hatched Egg Cup prints with supports for both the tricky overhang and bridge between the “legs.”

Similarly, a long or large bridge between two points in a design will fail without supports. Small gaps are manageable, but wider gaps should be treated like a 90 degree angle.

Think of it this way: Your print builds one layer at a time, like a layer cake with nice, thin layers. You can gradually build up curves and slight angles by adding differently shaped layers of cake, but if you try to build a sharp angle or add a layer in an area without support, your cake will collapse.

3) Orientation

Properly orienting your model is a vital step in the design process. Successful prints start with a flat base and build up in a way that creates gentle angles and easy bridges. A large flat base is more likely to succeed than a small base and a design with too small of a base could topple or fail to adhere.

It’s also important to consider details and lettering on the first layer. If details could be compromised because of build plate adhesion, orient the design so that the side with the most details does not face down.

For example, the Toothbrush Travel Buddy is printed at the angle shown below:

While this orientation creates a larger bridge, it’s still short enough for the MOD-t to handle. The Toothbrush Travel Buddy’s facial expression is not touching the build plate, allowing the details to print clearly. The internal toothbrush guard is supported by the base layer and prints vertically without issue.

  1. Tips & Tricks: Did You Know... - MadeWithMODt

    […] If you want to adjust settings even more, you can use a slicing program, like Cura, to adjust infill, wall thickness, brim presence, and more. Save your model as a .gcode file (also known as a “toolpath”) and it will create code that will instruct your MOD-t to take heed of your alterations. You can print this specialized .gcode through the New Matter desktop app. From the main page, click on “Settings” and then “Advanced Mode.” Your app will prompt you to load your .gcode file and then your MOD-t will load and print just like it would a New Matter Store design or an .stl upload. (You can get Cura profile information by emailing us at hello@newmatter.com. Learn more about formatting models for the MOD-t here.) […]

    I’ve written New Matter twice about obtaining the Cura profile and have never heard back. I keep reading to email, and I do, but no response.

  3. How To: Use Cura with the MOD-t - MadeWithMODt

    […] For extra control over your print (such as infill, brim, or orientation edits), we suggest using Cura, an easy-to-understand slicing program. Slicers break down designs into layer and create code to tell your printer how to extrude to create your print. Using Cura, you can rotate, flip, scale, multiply, alter, and slice designs with ease. You can even make your Cura display mimic the size and characteristics of a MOD-t to help increase your print success. […]
