Anyone have a decent 3D printer?
-
Holy crap - yea,.. that's a burnt print.
I have an Ender 3 Pro and it does a decent job of things... As long as, as with anything, you pay attention to a number of factors. Sadly I don't have photos of some of the prints I've done, and the photos I do have are ones I can't release.
Filament, speed, flow, temp and bed adhesion are may factors to deal with. I haven't been able to print ABS as it just peels right off. I do decent with PLA and TPU...
There is a lot that I don't know how to do and don't know if I want to try,.. but I've learned a bit also.
Here is a file I printed for a friend:

Few questions
What type of filament are you needing as there are many.
What is this for?
Was the file on ThingaVerse, or 3dCuts or another site?

I'm wondering if anyone have a decent 3D printer that works decent for precise printing and knows how to use it so it doesn't look like it was printing during an earthquake.
I attempted to print something for free using a local library, but when I picked it up, seen that it was just totally butchered.
Here's what it's supposed to look like, the .stl file:
And here's what I got from the library:
As you can see, just totally butchered.
If anyone might be able to help me out, I'd like to see what it'd take to get something like this or similar printed and sent. There's another design I'm testing atm.
Your first problem was going to the local library, where I guarantee they don't have anyone who understands the machines they got with the grant money.
Find a local maker space, or just shell out the $100 for a small one of your own. (Micro Center)

I thought since they had a decent 3D printer (Makerbot Replicator+) it would have turned out to be a least usable. I'm not sure how they let come out like that. It was printed in PLA, but I don't really care what's used, so long as what prints out is usable. I've never 3D printed anything, so I don't really know a whole lot about it, but given they have what seems like a decent printer and they operate a printing service, I thought it'd have at least turned out a bit better than it did.

I don't really know much about the filaments, but the PLA that was used seems like it'd be good enough once I sand it down to be smooth. Maybe other filaments are smoother out of the printer? I don't know.
This is a Tri-Bahtinov Mask for my telescope. I used a generator that outputs a drawing as a SVG file that I can open up in Inkscape to convert to polygon data, and into an STL file for 3D print.
Example I need, but not sure how well it'll 3D print:
-
@Obsolesce
I am sure there is a ratio and pattern needed for the mask, but how would your pattern compare to already designed models? -

Lots of thickness and pattern variance. The thickness doesn't matter at all (2mm thickness is likely fine), just that you don't want it to break easily or be flimsy. The pattern varies depending on focal length, and varies by many other factors. But it doesn't matter where the design comes from. The one I made worked very well. I printed it out on paper, cut it out with a razor blade, and tested it on my scope and it worked well. The only issue is that it's made of paper, very flimsy, etc.
I used Inkscape to convert it to a 3D model for STL. No issues there at all. It looked good in everything. It appears like every pattern on that site you linked, did it the exact same way as I have.
How much does the material cost and in time/electricity to print it?
I did end up finding them at telescopescanada.ca for less than $40 shipped. So I might just go that route if I can't get it done myself for less or without a ton of effort. I found 2 designs that work really well in my testing, and luckily one of them telescopescanada.ca is basically the same.

Makerbot Replicator+ is a good printer, it's just that it will never get the attention it needs for good prints at a public library. At least if it's anything like the public libraries around here that offer a printing service.

I don’t care to print it,… or at least start it. I can monitor and it it fails could stop it… but it’s not exactly a wild print.
If it’s imaged at the size needed I don’t have to scale any,.. guess is just an hour or so to print.
