The best part of this episode is listening to @siracusa talk about the limitations and benefits of different manufacturing methods when it comes to design. In this case, #3dprinting metal versus #cnc machining. It was totally spot on, and something that a lot of people don’t even consider.
Been working on a rocket injector demo. The high speed footage is just amazing 🤩
This is a "like-doublet impinging injector", which basically means there are two holes 90deg apart that hit each other, causing atomization and a fine spray.
I'm building a peroxide monopropellant thruster, so both streams are peroxide. An "unlike" injector would collide fuel with oxidizer to help mix them.
It started bc a Black security guard told some white boaters they couldn’t leave their boat docked where it was. The white boys beat up the Black guard, and then all hell broke lose w/ Black bystanders coming to the guard’s aid.
Then it got worse.
With #trump indictments, this looks like a full on class + race war is simmering, imo. Orange rapist stoking hate thru his SM today.
I'm warming up for a new #tool storage project. I still have my TTTTT on my desk but its overflowing! Has worked well for many years though. I designed it in @FreeCAD using the lasercut interlocking WB but used my small #CNC router to make it. It's still the only project I've published on @hackaday .io! Must amend that too! https://hackaday.io/project/174084
The recent consolidation in the #3DPrinting market has been interesting from its lofty promise back around 2015 or so.
I can recall many pilot programs at many manufacturers that I saw personally.
#Manufacturing is a tough nut (perhaps, the toughest nut) to crack in terms of displacing entrenched, proven processes like #CNC machining and casting.
It's been awhile, and there are lots of new users on here, so time for another #introduction post.
I'm Benny from CT, USA. I'm a #CNC#ProductionManager. It's high-stress and I hate it. I've been happily married for 20 years to my wife who was recently diagnosed with #cancer. She has #RenalCellCarcinoma and is currently undergoing #immunotherapy.
Is there anyone here making physical objects with #3D#CNC machining?
last time I set up a workflow for this was 2018.
It was/is:
Inkscape to draw arbitrary but precise 2D shapes, then export those as an array of values which can be used in #openscad, where most of the design work is done.
I've extended openscad extensively, but it is still a lot of work to use. That said I now have a large base of stuff coded in openscad so anything else would have to be really good to get me to switch.
Once I have a 3D model I then have to switch from #linux to windows where I use #Estlcam to generate toolpaths for machining.
(I also 3dprint some parts but that's outside the scope of this post)
I'd like to hear what software others are using and why. Also any recommendations for 3D toolpath generation on linux so I don't have to switch to windows mid-flow.
To give you an idea of the sorts of shapes I am making and the scale of the challenges heres the main product:
One of the perennially popular pages at Maker Forums is this one, which people are clearly finding because they are searching for a solution to a problem, and there are enough relevant terms in the question to find the post and the solution.
It's not magically great documentation, but being a public repository for questions and answers, problems and solutions, makes me feel good about spending time maintaining Maker Forums. ❤️
