One of my biggest pains with the HP 3D printing system is having to manually redo builds when changing parts (like, with printed PO numbers etc). If you had a full build of Model A, then changed it slightly, you would have to remake the build.

I’ve developed an experimental open-source utility that replaces part geometry in existing HP SmartStream SSP builds while preserving placements. It requires a compatible SmartStream installation.

You open the build, identify the parts you want to swap out, choose a new file, and click update! A new build saves, it doesn't overwrite the old one.

Let me know any thoughts, completely open source, so please add any improvements you want.

Disclaimers:

This is an independent project, unaffiliated with and not endorsed by HP. The program is completely coded by Codex - but it is opensource, so if you want to make your own, please do.

I have only tested it for a day, so double check all your builds before you print them.

Hi! I want to 3D print this aerospike nozzle (approximately 22 mm outer diameter).

It would be attached to a tube containing potassium nitrate and sugar propellant.

I'm looking for a low-cost material that could withstand at least one firing.

What material and type of manifacturing would you recommend?

Thanks!
