My next model will be a collection of the most common battery sizes.

We have a new obsession: printing calibration butterflies on our INDX. Otto the calibration butterfly is the model we recommend starting with. As the name suggests, we designed this model to verify that your printer is properly calibrated after assembly, while leaving you with a cool first print you can show off. 🦋 https://t.co/AzmFFle1SM

Which of the following ideas should I publish as a 3D model?

Falcon 9 launches the 17th Transporter rideshare mission and delivers 81 payloads to orbit

[Prusa3D @Prusa3D]

INDX keeps filament waste to a minimum. 🗑️❌
Its priming pellets are incredibly small and lightweight - around 0.013–0.015 g on average. Compared to other multi-material solutions, that’s just a fraction of the waste, making INDX the most filament-saving multi-material system on the market. 🦾♻️

I want to know what is your favorite printing material and why. It will help me create better models for you.

[World of Engineering @engineers_feed]

Diamond is the hardest natural material, meaning it resists scratching.

But hardness ≠ strength.

The strongest natural material by toughness (energy absorbed before fracture) is nacre, mother-of-pearl.
It's 3,000x tougher than the calcium carbonate it's made from, because of how the layers interlock.

Molluscs engineered a composite material 500 million years ago.
We're still copying it.

If you are interested in protecting the environment and printing with biodegradable plastics, PLA is not the best option. PHA is a filament that is fully biodegradable under normal conditions and is produced by bacteria.

In my designs, I always aim for functionality while using the least amount of material possible. My mission is not just to create something beautiful, but something that solves a real-life problem or serves an educational purpose. #3dprinting #3dprint

My next model is out! It is a representation of a lithium atom.

Teams recently completed build and acceptance testing of our 1,000th Merlin 1D engine for Falcon’s first stage! With Falcon’s reusability, recovering these engines has enabled continued reliability enhancements, making Merlin one of the most reliable rocket engines ever manufactured

[Sebastián Alejandro @SebasDeAce3d]

I am putting the finishing touches on one of the following models: a scale-model wind turbine that is ideal for understanding how it works. It will be only on @Cults3D

[Sebastián Alejandro @SebasDeAce3d]

From now on, I’m going to start running polls on X twice a month so you can decide on my future models.
All the exclusive models will be available on Cults3D
