3d Printers

[Root Cause]

Guilty as charged but in my defense, it was a blanket statement that 3D printers were useless. I did not think that was an appropriate way to leave this thread.

wasn't aimed at you, mike has posted this in another thread as well, not entirely sure why he hates them so much.

I'm not really a tech guy, but im hoping 1) to be able to spit out some useful and neat stuff; and 2) get kids interested in the design kinda stuff. Even if its existing models, being able to see a design or model turn into a finished object.

I imagine the first dozen prints will be silly figurines;

Paul, by now you may know this but there are thousands of free programs out there. My grands had fun with whistles, Batman logo's, etc. It really is limitless. By the time you have 4 or 5 things made, you will move on to things that specifically interest you and your kids. good luck

These were printed with an iron powder impregnated plastic.
A little forced rusting is being done now. The pieces look like weathered cast iron afterwards.
It will be a light switch when assembled. Gift for a young relative.

You running Klipper or Marlin firmware?

Marlin 1.1.9 if memory serves me correctly.

Marlin 1.1.9 if memory serves me correctly.

You might look into Klipper it’ll help speed up the prints as well as help with the ringing that’s showing up there in those prints.

I was unfamiliar with the term "ringing" so had to look that one up. The various references I read seemed to indicate that it is a result of mechanical vibration or resonance during the printing process. It mentioned that it is commonly the result of quickly changing direction which can cause vibrations. I'm somewhat confused because those tail pieces (I assume those are the ones you said show ringing) are hollow with no fill. As such, the wall thickness of them is quite thin and very little starting and stopping is going on. I'm not sure how new firmware would help resolve that but it looks like I need to do more reading. One thing for sure, 3D printing is a constant learning process, at least for me.

This is my latest print, it's a T Rex, it's about 6 1/2 feet long (about the size of a two year old.) I have two more pieces to attach, one of the legs and one arm. The black skull set is 18 inches long.
