When I joined a week ago, I was stunned by how many #3DPrinting folks are already here. Great "Starter Packs" below!

Another teacher and I received a small grant from our school's parent foundation for 3D printing to support our math classes. Thinking class sets for hands on for students and larger models for display. When choosing filament, it was Printed Solid Jessie PLA all the way! @printedsolid.bsky.social

🎉 New Post: Saddle Surfaces!
These were inspired by some of my Calculus III lessons. I'm excited to share them with my students! I particularly like the contour map surfaces and will probably use the technique again more.

My "Double Integral" models are now at Cults3D.

These are terrific for my Calculus III class, and the added bonus is that my younger students started asking questions about higher-order mathematics as well!

Over 60 models included. Link in my bio and below in comments. @cults3d.bsky.social

New post! 🎉 Exponential Curves!
They can be used for logarithmic functions too. These have worked really well in class with my students. Now available at Cults3D in 4 versions and with STL files for fast class set printing. PDF blank axes also included. @cults3d.bsky.social

New post! 🦕 Dinosaur Wall Art! 🦖
My Dinosaur Blocks are so cute that I wanted a way to display them bigger! Easy to rescale, these have a lot of possibilities.

Oh, Yeah!
This will be fantastic for front-of-the-class demos.
And I printed it in PETG! Not my usual material at all.
Printed Solid Cyan PETG. Model soon to Cults3D.
See details in original post below.

My printed exponential curves worked well in my lesson! Many students (though not all) thought it helped to better visualize what was going on as we transformed the functions. Students commented they liked "hands-on" approach. Curves w/ bases 2, 3, e, 10 coming soon to Cults3D. @cults3d.bsky.social

Last minute idea for today's lesson: Exponential Functions. Each one is the curve y = 2^x. I made a class set for myself and each of the other Math 1 Honors teachers. Maybe e^x is next, or a longer tail toward the asymptote... 🤔

Woah! Atomic Filament "Bug Eyes" and Printed Solid "Yellow Bird." This kit card was printed with three filament swaps at key heights. I think I like the bottom side better than the top! 🦕🦖

I'm so happy with how my Dinosaur Kit Card came together when printed on my @prusa3d.com XL! Check out the flip side in the comments below. 🦕🦖

Giving up for now, but open to food for thought...
Trying PETG for support interface layers on XL. Issue seems the PETG won't stick to the PLA in the wipe tower. It make globs that then stick up and get caught in the nozzles, etc. The support itself seems to be printing fine. 🤷‍♀️

Intended as a 360 x 360 print to clean a stain on the plate, but I couldn't let such a nice top surface go unused. 🤔

My son chose to make it a sign for the Haunted House at his school Halloween Carnival! 🎃

Interesting to watch XL startup process on it for printing the words.

Fancy new build plate or a two-layer blank canvas? 🤔
