I think the fundamental problem here is that most GUI creators, whether web or app based, do not value the intangible time that thousands to millions of their users have invested into productively using their systems. (Or the value they will be forced to expend anew to continue using the...

Hmmm … that’s news. Interesting. I face the typical independent Engineer’s problem. Once I explain the solution and the niche market it works in … neither party has any use for me further. Getting some kind of legal agreement up front is expensive/wasteful. I’ve seen a couple ‘good...

1000-2000 per month to begin with if strength and economics line up. What are your thoughts?

Please fix "EDIT" so I can revise text to improve it when more info becomes available. Tnx! Bruce

These material samples exhibit really high stiffness with just a smidge of flexibility to take a hit w/o fracturing. The product is a composite construction siding described as a "proprietary polymeric resin and granular stone" (called C Core - Chelsea Building products) probably targeted as a...

It would be nice if clicking on my account would let me see a list of all my past posts ... that was massively helpful. Best regards, Bruce

Dave, Thanks for the Roark tip. Will look for it. Greg, I fully expect your estimate that the error will be tiny is right on the money … being new to this I need to burn some time assuring I am on the right track. Thanks Guys! Bruce

Greg, Those are about as impressive as it gets! But I was curious more at a basic day to day working level. I’ve been experimenting with smaller packages and seemingly getting plausible results, but I was looking more for a model(s) I could duplicate, run and compare my results with “known...

Are there any standard 3D models with material and load data that can be downloaded for testing of computational accuracy of FEA tools? (Or some equivalent?) Best regards, Bruce

Hi WK, Structural, mix-expanding-curing. Further research points needing a foam that cures to 12-16 lbs / cubic foot. (~300psi) I need to find a couple sources that can provide test samples to hone this in tighter. Thanks! B

Brian, Excellent site ... this looks like quite a good eng materials resource. Thank you for taking the time to share it :^) B

Can anyone recommend a good supply house that can deliver medium & high density PU foams? I spent 5 hr yesterday surfing/calling and only found one guy interested in making a sale, but he had to go find someone that could answer questions about their foams’ performance specs. I scan chemical...

Yep, the X1E has it ... plus about another K in cost over the unit designed without it. https://www.matterhackers.com/store/l/bambu-lab-x1e-3d-printer/sk/MEQ5KJ70?rcode=SC_X1E&gad_source=1&gclid=Cj0KCQjw0Oq2BhCCARIsAA5hubWkkRuJt8n6QA83EznVQZ1FEzevX79a_p7qbo0Bfx7zB70yfjLI1UwaAudIEALw_wcB...

Thanks for your comment! Interesting. Does it have a bare RJ-45 jack? Another source (that could be wrong) said it was WiFi only. The PRUSA has a WiFi module that can be popped off from a vid I saw.

I have a friend that has a PRUSA and swears by it. In my first look, I like that you don’t need to have it tied to the cloud. Bambu has some attractive features/pricing, but from my reading, you can’t run w/o being exposed to the Net. That’s a non-starter for my customers. Can’t blame them based...
