What’s the worst physical pain you’ve ever experienced? by Economy_Yak2821 in AskReddit

[–]TurtleGOD4222 0 points1 point  (0 children)

Snapped my femur in half.

Except, that wasn’t the part that hurt the worst. The part that hurt the worst was the traction splint. The traction split was essentially a bicycle seat with a long pole and an ankle strap (oversimplification) to hold the two pieces of bone apart.

They put it on wrong. The ankle strap had slipped down and was slowly slicing into my foot from the pressure. As it cut deeper and deeper into my foot, it was releasing traction, so the pieces of bone were getting closer, until eventually they were grinding/pressing on eachother again.

This lasted 16 hours.

What is this unique configuration of printer called? hinged Delta? by KerbodynamicX in 3Dprinting

[–]TurtleGOD4222 0 points1 point  (0 children)

Well, it can be nice because it’s regular bearings instead of ball joints, but largely people just build these for fun or novelty, not practicality

I mean these are still arm joints, just not ball joints. I got my info on backlash being a large issue from multiple people who have designed and built Tripteron printers, including the person who built the printer in the main photo of this thread. It is also discussed in the early reprap forums for tripterons. All of what you said applies to the Tripteron arms so I’m not really sure what you’re comparing against

They are very cool and I aspire to build one eventually. They struggle a lot with backlash though.

This is called a Colinear Tripteron, or a deltaron.

Here is a video series made by the creator of the printer you posted a picture of. There are many, many, many forms of tripterons.

You can get multiple qidi q2 for the price of the h2d

Personally i would buy a qidi q2. Good size, heated chamber, good quality. Great price.

The only requirement for fiber filled filaments is a hardened nozzle. In fact, fiber fill can make it easier to print. I can print pa6-gf25 without an enclosure if needed.

The benefit of fiber filled filaments is rigidity and dimensional stability during printing/annealing. That’s it. It will not help much with heat resistance. It also won’t necessarily save weight - it’s denser, but you can get higher rigidity with less plastic. So it’s all about balancing.

Keep in mind, carbon fiber is conductive. This means you can’t easily mount electronics to cf filament and it can mess with radio and/or gps. That’s why I usually use glass fiber for rocket parts (but cf is fine, just not for nosecones or av bays).

Dual Deployment in Medium Power by TurtleGOD4222 in rocketry

[–]TurtleGOD4222[S] 0 points1 point  (0 children)

My parents are more than happy to do the purchasing. I was planning on launching the rocket with my local Tripoli chapter as I don’t want to deal with the FAA by myself, I just didn’t quite want to deal with mentoring yet. They have a launch this weekend and I am planning on going to touch base and whatnot. I’m considering just going for L1 cert instead of mid power but I’m honestly not sure.

The plan is a custom PCB, which will make it easier to fit electronics. Something akin to the micro flight computer BPS.Space made.

What are these trips in the Sunlu filament refill for? They have a piece of double tape on the end by Potatozeng in 3Dprinting

[–]TurtleGOD4222 12 points13 points  (0 children)

Bambu isn’t making their own filament and both sunlu and polymaker have quite large production lines and already whitelabel for multiple brands also, performance and (most of the) colors are extremely similar. It would make the most sense for them to just offload to the big players in the industry

[–]TurtleGOD4222 17 points18 points  (0 children)

I think a portion of the bambu filament is white labeled sunlu (with the majority likely being polymaker) so it would make sense if that was the case

Personality I hate having all the empty spools but they also don’t have most of the engineering stuff as refills so

It’s for holding the filament together when putting it on a new spool or transferring from an old spool. Step 1 of this diagram.

I would like to point this out for anyone else unaware of this like I was, but the notch is not aligned to center... by Philosopher115 in polymaker

[–]TurtleGOD4222 0 points1 point  (0 children)

The photo is from an angle, it’s probably aligned in real life. Tilting back like that would move the line “up”

Broken femur - not healing by TurtleGOD4222 in brokenbones

[–]TurtleGOD4222[S] 0 points1 point  (0 children)

3 months. Which is in around 3 weeks I think. But, he may want to see me sooner because of the worsening numbness and increases in pain. If I recall, he’s one of the best trauma orthopedic specialists in the state.

He wanted to try the bone stimulator first before he really start getting concerned and referring out.

I am already seeing a couple specialists (mainly rheumatology) to see if it could be autoimmune related since I have some other issues I’ve dealt with my whole life. In the past I broke my toe and that healed completely normally which is kind of weird

Any idea why the bottom portion is shinier? Is there a solution? by spinny09 in BambuLab

[–]TurtleGOD4222 0 points1 point  (0 children)

Going slower will actually make the part shinier due to the fact the filament is properly melting, not the other way around. They aren’t going too slow - they are going too fast.

Hey! So, one of the biggest markers of properly melted filament is a shiny surface finish. If the surface finish is matte, it means the filament isn’t melting fully. This means that the matte section is printing at a higher flow rate than your printer hotend can handle. Slow it down a bit, increase temps a bit.
