Fun with 3D printing! Here's a stick puzzle made up of 30 identical sticks - each piece represents an edge of a dodecahedron which have been rotated by a constant angle. George Hart wrote a great paper about how to design these models: archive.bridgesmathart.org/2011/bridges2011-357.pdf
Walking by a store that filled with the 3D printing colorful objects, like cartoon characters and animals。It as really cool to watch how's the 3D printer to print this kind of 3D objects.
Finally finished this guy, now for cutting into pieces for printing and then onto molding and casting!
This design looked pretty straightforward until I started it, managed eventually, after many attempts!
How I did it...
created a sphere
squared it off on 4 sides
applied 4 45 degree chamfers
hollowed it out
added the hex holes
made a copy
created the bar
connected the bar to each of the ends.
3D printing offers engineers various ways to construct hardware that simply could not be built in any other manner – such as this single-piece casing to house an optical instrument for Earth observations.
In this case, the desired shape was initially 3D printed in wax. The wax model was then dipped into a ceramic slurry to create a hard shell.
The wax was then melted away and molten aluminium poured in the hollow ceramic mould to produce the final part.
This prototype casing demonstrates another potential advantage of using 3D printing to create very complex space parts in a single piece.
Extremely complicated shapes can be manufactured without the need for joins or welds, using less raw material and energy than traditional manufacturing, and with a reduced number of steps.

Unlike previously-seen 3D-printed parts, these actually saw release as 3D prints, demonstrating play functions that couldn't be achieved through injection molding — at least not as simply.
The drafting arm (not pictured) was released inside set 4000034, given to LEGO Inside Tour attendees in 2019. It can be moved back and forth within its holder, but returns to center.
The pogo stick was teased as a pledge reward for the book "The Secret Life of LEGO Bricks" in 2020. Blue and red were distributed randomly when the book was finally released in 2022. The campaign was limited to 500 of these rewards, but more may exist. The shape of the plastic functions as a spring, with a center rod keeping it straight.
The classic duck was first given out to Skærbæk Fan Weekend attendees in September 2022, then available for purchase at the LEGO House for 3 weekends in November 2022. Several colors were shown, but only dark red has been released so far.
The gear keychains were given out only to LEGO employees in Billund, in late 2022, to celebrate the Production and Qualifying development departments that are creating these new products. The gears spin freely, though they are trapped within the one-piece casing. These came with a standard 2x4 brick keychain attached.

The ESA–RAL Advanced Manufacturing Laboratory on Harwell Campus, UK, assesses new material processes, joining techniques and 3D printing technologies for application in space.
Polishing samples is necessary for microstructural analysis because it creates a better surface finish when analysed through a Scanning Electron Microscope, for example. At the end of the polishing process, the metal surface reveals the material’s microstructure and texture, making it reflective.

3D designing has taken up lots of my time this winter, a real obsession for sure. As the weather improves I will definetely be outside more with my camera and get off this addiction for the summer!!
Recently I had the opportunity to use some 3D printers, and I decided to use them to make the Nuva Cube. The cube is made of PLS, has a length/width/height of 2 inches, and is composed of four 1 7/8" x 1/8" x 2" and two 2" x 1/8" x 2" faces each glued onto one of the sides of a 1 3/4" cube (rather, that's the dimensions of the computer model… as you can tell, the technology is still pretty finicky, and the measurements don't always come out right). I designed it in Tinkercad and glued all the pieces save one together, but the actual printing was done by someone who actually knew what he was doing. :P (The piece I didn't glue was the one on the bottom of Lewa's face since I wasn't there when it finished printing and it was the last piece not yet glued on.) I also have to give credit to fearmaker782 of deviantArt as I frequently referred back to his own System Nuva Cube during the design process since each face is set up on a clear 8 x 8 grid.

So interesting to see how different they are unpainted and after a bit of care!
Two classic-version 3D-printed Makies, they underwent an #orchidmakeover to transform into their new selves!
My client gave me full reign over their features, such a nice thing to have such trust put in me as a customizer.
