Laser Cutting from a 3D File

Laser Cutting from a 3D File 640 480 mathgrrl

To make files for laser cutting, you need two-dimensional information. You could download a picture from the internet, draw something yourself, or create an image in a program like Illustrator or Inkscape. In this post we’ll walk through the process of creating a 2D-laser-cuttable SVG file from a 3D-printable STL file using the free online in-browser modeling program Tinkercad.

Origami Press #2: Yoshizawa Butterfly

Origami Press #2: Yoshizawa Butterfly 2016 1512 mathgrrl

Our second origami press is a helper for folding a beautiful and elegant butterfly model designed by Akira Yoshizawa. One of the final folds of this butterfly model pulls the paper together past its natural fold line, which is what creates the organic, curvy shape of the finished model. This press enables the folder to make this crucial fold very cleanly and thus produces a more reliable butterfly model…

3D Printed Origami Press – Miura Fold

3D Printed Origami Press – Miura Fold 2016 1512 mathgrrl

This weekend we’ll be headed to the MOVES 2019 Conference in NYC at MoMath, organized by mathematicians Josh Laison and Robert Vallin.  This year, MOVES is origami-themed and features keynotes by Erik Demaine and Robert Lang. In honor of the occasion we’ve decided to design 3D printed “origami presses” that push crease patterns into origami paper…

Pi Approximation Day – A Holiday for Hacks and Amateurs 500 370 mathgrrl

The 3D printing community is full of self-taught hacks like me who are DIY “expert amateurs,” meaning that we have lots of experience doing things that are a bit out our league. As recently tweeted by @stevenstrogatz, “if it’s worth doing, it’s worth doing badly”…

Stacking 3D Models for Bulk Printing

Stacking 3D Models for Bulk Printing 840 630 mathgrrl

Sometimes printing multiple copies of a design can make it much more affordable. Shapeways prices depend on many factors, including how much space is taken up in the printers, how much material is used, and other processing considerations. Understanding pricing and then designing to optimize price can make ordering your own prints more affordable, and allow your store products to be more accessible and attractive to customers. In this article we’ll compare the cost of printing items individually and in bulk, and show how to efficiently stack and loop objects for inexpensive bulk printing.
