Reef 3D printing request thread

I can’t speak to what Eric meant, but I think you definitely want to do option A

I think that’s what he meant. That’s how I would’ve printed them. Just wanted to make sure. Logically it seems the best orientation strength wise because the weight will be pulling downwards holding the light

Appreciate it but it’s not insanely urgent - I’m ok waiting a week and meeting up next weekend. If you get it in time and print it OK I can come down to Neptune this weekend though. Whatever is convenient for you!

Just ordered the filament should be here tomorrow. I can print overnight and have it ready Saturday. I’ll pm you Saturday morning to let you know they printed successfully

@Srt4eric if you meant A it would have to be made in two batches.
B can make all 8 in one batch just have to use supports

@derek_SR If you want it me to make it and have it ready for Saturday I’d have to know pretty soon. I don’t have any ASA but Amazon has the filament for next day delivery if I can meet the deadline tonight. I can get it delivered tomorrow and just print overnight to have it ready Saturday. It’d take roughly 8hrs to print with 100% infill and 0.1 layer height

Lay it on its side. The layer lines will go all the way through instead of the layer lines going back and forth

To elaborate on why, the main weak point in a 3d print is the connection between layers. Imagine the layers are like LEGO pieces stuck together really hard.

It's a lot easier to pull layers of LEGO pieces apart then it is to rip a single LEGO apart. Same with the prints. Avoid anything where layers can get pulled apart.

On that print, looks like a nice design, but as a non-expert who does some of this as a hobby, it's my understanding if you're building a strong part you also want all corners to be smooth/fileted in the design. It's hard to tell but it doesn't look to be in that one. May not mean anything, but also might mean the person designing that wasn't the bestest expert, so I'd be careful. That seems like a thin part. I'd also have wanted it to be thicker, with the print being solid because of multiple walls.

Question for you since you’re here. Eric mentioned something to me about how he read somewhere 99% infill is better than 100% for some reason. Do you know anything about that?

The design did look thin to me at first but looking at Kris Cleven’s designs, they all seem pretty thin? Maybe because the lights themselves aren’t that heavy?

I'm not familiar with the 99% vs 100%. My understanding is that high amounts of infill is less effective than adding more wall layers though. Both in that 100% made by pushing the number of wall layers up and up is better than infill, but also that if you do a bunch of wall layers you don't necessarily need more than say 20% infill in extreme cases.

I'd have to do some more reading
