interesting. so what would someone do with a clear inflatable tube? The tubes are so rigid even with just a few PSI that they can be used as structural elements. They have been used as inflatable supports in temporary outdoor structures such as tents and shade covers, with the ability to quickly as...

For a thin wall inflated tube, 5 psi might not seem like much pressure but it is significant. Consider the average inflatable has less than one half PSI and the Goodyear Blimps are inflated at .07 PSI. While you can't really see the 3D printed two-piece plugs holding the ends of the 24 ft long tube ...

I've noticed that when using acetone to smooth out the surface finish of an ABS part, the acetone seems to wick into the entire thickness of the part and weaken it. I've had press-fit parts split (perpendicular to the layer plane) and threaded parts pull themselves apart when surface finished with a...

Wow, that seems like such a simple piece it's hard to believe the molds are costing $10K each. I've only briefly searched mold prices but I thought I saw $3K somewhere for simple molds and it wasn't a Chinese company. I would think CNC mills would allow making low cost molds for simple small parts l...

Something like this? http://reprap.org/wiki/Print_Troubleshooting_Pictorial_Guide Yes, exactly what I was thinking. I've found that if you can think of something useful, someone else has already thought of it and you can usually find it on the internet somewhere. That guide could be vastly expanded...

Hmm, this forum didn't do that. Maybe I'll just stay here. BTW, do you know if anyone has ever created a pictorial glossary of all the common 3d printing defects along with the settings that cure them? That would be a really useful thing to have as a reference. I've thought about taking pictures of ...

What is up with the Simplify 3D forum moderating every single post? Everything I post there never shows up because it's waiting for moderation that never seems to occur. Why would someone even bother looking at every single post that forum users make, or even have the time to do that? I'd post this ...

Makes sense now. My old flashforge had 4 bed leveling screws and it could sometimes be a pain to get perfect but it made more sense to me. I guess I just have to get used to it :) I have tried all the different bed leveling techniques in the Forum and each one seems to have it's ups and downs (pun ...

Acceleration is not the same thing as print/travel speed. The extruder can't go from zero to the target speed instantaneously. Acceleration controls how fast it attempts to ramp up. The S3D advanced tab sets those target speeds, the M201 controls the steepness of the ramp. If you just remove the M8...

Completed and published 2 videos to YouTube about my new spoons. Kinda hate to see this phase be completed. Designing things, tweaking lures is the fun part and extra interesting that pulls me in whole hog. Ha, I know what you mean. I'm always tinkering with new inventions and keep thinking, you kn...
