Speed Racer Testbots
Speed Racer Testbots 640 480 mathgrrl
It’s hard to find a better test print than the Ultimaker robot; it has insets, embossings, overhangs, bridges, and posts, all wrapped up in a model that’s less than an inch and a half tall. Plus, it’s cute. This robot is small and prints quickly, but… on an Ultimaker with standard Cura settings, not quickly enough! The Dutch print for quality but I want to print for SPEED. Time to turn the Ultimaker robot into a speed racer… // Hacktastic

JMU 3SPACE: Building a 3D printing classroom
JMU 3SPACE: Building a 3D printing classroom 1004 754 mathgrrl
Over the last four years, the JMU 3SPACE classroom has supported 3D printing across the curriculum by hosting general education classes, courses in mathematics and art, projects in history and biology, workshops for local K-12 school groups, faculty workshops, and even a 3D printing club. We’ll walk through how 3SPACE went from ideas to equipment to curriculum… // Guest post at Ultimaker Education

Customizable Snowflake Cookie Cutters
Customizable Snowflake Cookie Cutters 628 472 mathgrrl
For the past three years we’ve made a holiday snowflake design: In 2013 it was Snowflake Ornaments, created by extruding an SVG image. In 2014 it was the Snowflake Cutter, which mimicked the way snowflakes are cut out of folded paper. In 2015 it was the Snowflake Machine, which could generate over a billion unique snowflakes in different styles. What could we possibly make this year to top that?… // Hacktastic

3D Printing Knots at the Unknot Conference
3D Printing Knots at the Unknot Conference 640 480 mathgrrl
At this year’s UnKnot conference, Lew Ludwig and Chris Faur set up two 3D printers: a Ultimaker 2E+ and a Formlabs 2, including a UV-light drying station with a solar rotating stand. During the conference, mathematicians designed and 3D printed original models of pretzel knots, hyperboloid stick conformations of torus knots, hexagonal mosaic tiles, and rolling trefoils… // Guest post at Ultimaker Education

MyMiniFactory + mathgrrl 404 306 mathgrrl
Laura Taalman, otherwise known as mathgrrl, has been prolifically uploading 3D models to the My Mini Factory platform since 2013. She now has nearly 200 models online, all available to download for free. She is also a Professor of Mathematics at James Madison University, a talented 3D designer, and knows her way around an Ultimaker 2… // Designer Spotlight at MyMiniFactory

Cube Puzzle Quartet
Cube Puzzle Quartet 628 472 mathgrrl
This year at Maker Faire Bay Area we hung out at the Ultimaker booth and offered a challenge: Solve one of these 3D-printed Cube Puzzles and you get to keep it! All of the pieces can be printed without support, and the puzzles and container are free on Thingiverse or YouMagine. All four are classic puzzles that you can read about in Stewart Coffin’s excellent book Geometric Puzzle Design… // Hacktastic

Girih Tiles for Interactive Islamic Designs
Girih Tiles for Interactive Islamic Designs 628 472 mathgrrl
Girih tiles are used in Islamic art and architecture to create intricate woven strapwork patterns. Their underlying periodic patterns are related to Penrose tilings and predate the formal mathematical discoveries of such tilings by at least 500 years. The basic colorful tile shapes determine overlaid strapwork in the middle, which is accented on the right by concealing the colorful tiles with gray ones… // Hacktastic

From Prototype to Product: Snowflakes
From Prototype to Product: Snowflakes 640 480 mathgrrl
Time to level up and convert our desktop 3D printer models into designs optimized for printing on industrial-level printers. Shapeways is basically a personal remote factory where you upload designs and then have them 3D printed in various materials and mailed to you. That’s easy except for one catch: designing for industrial-level 3D printing is not the same thing as designing for desktop 3D printing… // Hacktastic

Minecraft Star Wars Trash Compactor & 3D-printed Remote Control Pants
Minecraft Star Wars Trash Compactor & 3D-printed Remote Control Pants 628 472 mathgrrl
I think I may have been waiting my whole life to write that title. For the littlebits bitWars Challenge we teamed up with Minecraft adventurers rileypb and cgreyninja to re-create the Trash Compactor Scene from Star Wars. Redstone and pistons were activated by a cloudBit that allowed real-world interaction, and we also included an automatic silverfish generator and a villager to play Chewie… // Hacktastic

The Snowflake Machine
The Snowflake Machine 628 472 mathgrrl
Our new Snowflake Machine uses random numbers, mathematical algorithms, computer code, and SCIENCE to create well over a billion unique and beautiful snowflakes, with an algorithm that approximates the way that snowflakes grow in real life, with branches and plates determined by a random seed. Choose that seed, and then set style parameters to determine fullness and fuzziness… // Hacktastic
