The 3D printer thread

If I were to design something, and start selling it, I haven't shared the files. Someone else could copy what I've done.

If I was in their shoes and saw that they made themselves a copy, I wouldn't be mad.

If I saw they distributed it for free, I'd be more upset, but I agree the info is out there, and it's bound to happen.
Just do it in a Chinese accent :flipoff2:
 
Something that might help someone else. I needed to print a few things with 100% infill. They kept coming out fuzzy and terrible quality. I saw online that instead of changing the infill, change the number of top and bottom layers to 999.

I printed it last night and the part came out perfect.
thansk thats a neat idea
 
this is my tpu drama. from what i am reading i maybe wet filament. so now its drying for 10 hours in dryer

but also been reading i need to slow down speed of travel

i am using creality for my slicer and the setting are hard to get too, some menus is some stuff and another menu is the rest. what a better slicer? i think i used orca but then i got the k1c and just used the default slicer.
 
Quite a few places I read said to use a new nozzle for tpu, one that hasn't run a anything else yet.

I took the opportunity to switch to a 0.6 at the same time.

I like to print a benchy or a temperature tower first instead of the thing you're trying to print.

I like orca. There's probably a machine profile for you k1 so you don't have to figure that out.
As soon as elegoo follows the ****ing license and puts the network module into open source ill be free of the propretary version myself.
 
This is gonna be fun.

The irony of a Chinese company claiming copyright infringement. IP theft is one of the pillars of thier business strategy.
 
i found it on thingiverse


So I played with this some more for the heck of it. A few issues:
  • It is scanned at a pretty high resolution, so there is a lot to work with. I cut it down to 25% of the polygons (which took awhile) and that made it much more manageable to deal with.
  • The form isn't closed since they only scanned one side. That makes some operations more difficult to deal with.
  • I'm just learning the mesh stuff with Fusion, so it isn't fast and I'm probably doing things wrong.
However, I got to the point where I could at least make a divider for the tray. I know, not much, but something and it has spurred me to learn more.

Have you learned how to Mesh Section Sketch yet?
 
if all you want to do is print fancy materials for functional parts, yes.
you can still do multi material prints. The slicer will pause the printer and it will wait for you to manually swap the filament and push a button.
it's just way less convenient so you'll never do it.
How do I get it programmed to pause?
I have 1 project that I would like to try multi-material - Basically a PETG oil cap and a TPU gasket. If I print the cap upsidown, the last layers would pause and switch to TPU.

other than manually hitting pause button at just the right time, how do I get multiple materials together? Will the TPU bond to the PETG (so I dont have to use adhesive of some sort)?

I am using orcaslicer
 
Yeah several different ways but they are all like that, in the Cura there was addon's you could use to add pauses at layers, I think it's easier now more integrated into the slicer.

I don't think the TPU and PETG will bond.
 
I ***led this file "Bird Poop Preventer."

Tired of the birds clogging up our rain gauges, this is version 3.0 or there about. First version was a plywood circle with the same spike strips screwed to it. That first version was mounted to the post that the rain gauge was on and made servicing the rain gauge a little more difficult. This one being attached to the rain gauge should make servicing simpler. Two thumb screws, and about an eighth of a turn of the cylinder, removes the entire cylinder, and the spike strips come off with it.

Creality PETG, some McMaster Carr hardware; stainless self tappers, 10-24 thumb screw, and and hot melt threaded insert. The bird spikes are some random Amazon offering.

Made a little passthrough housing for the fuel cell. This is just a first draft, definitely don't need that many fastner holes. The scale of it was difficult to judge while designing it.

Going to print a tpu bushing for it, and a whatever top plate to secure it. Kinda just sandwich the bushing in the middle. Bought some heat set inserts to try out.

Make sure your holes are slightly larger that the od of the smooth bit of your heat inserts or the melted plastic pushes up into the threads.

Btdt.
