3D Printers

@brenda lol
This is it. I am done with these critters for a while.
Currently printing a 300% version of this Ghost ship in the color changing filament. It's a 26.5 hour print job.

The 26 hour ghost ship print failed about 1/4 of the way through. Corrupted G-Code it seems. I will try again someday but I have other projects in mind first.
This is the current print happening right now. It has about a 13.5 hour print time. It is a case for a Raspberry Pi 4b 4GB with a HyperPixel 4 capacitive touch screen. I am going to use it for the Octoprint app running under Linux to remotely monitor and control the 3D printer. The system will have a hi-res camera watching the print bed. It will ride along the Z axis so I can monitor the nozzle visually anytime during a print.
I laid all three parts out to print at the same time. It downloads as three separate files.
I am printing it in Jet Black.

The Raspberry Pi case turned out good after a couple of failed attempts to print everything at once. I separated them into 3 different print jobs and it worked much better. Not crazy about the case design.
In the latest development, the Raspberry Pi is now feeding the printer and streaming video of the process.
I worked on the Raspberry Pi and the HQ raspiCamera until 3:00 am this morning. The time involved included the fact that I was attempting to install a cooling fan which involved some soldering. But then the supports for the fan broke off in the case, and a few choice words were spoken. De-soldered. No fan for now. Installed heatsinks. I tried for a long time to get Octoprint to work with the camera, but I ended up frustrated and decided to go with the mjpg_streamer method. The process involved compiling mjpg_streamer and creating a script so it auto starts on boot. Yes, that was easier then getting Octoprint to see this camera. lol I could find very little out there about it.
In any browser on my LAN, I enter http://raspberrypi.local:8080/stream_simple.html
The first print I did with the Octoprint controlling things was of course an articulated octopus.

@mark That's very cool, Mark. What are the dimensions? Will it fit in an aquarium? I can picture fish swimming through the openings.

@brenda The Ghost Ship is a heading to my Uncle as a decoration for his pool deck porch. I am also printing a pretty cool looking sailboat for him.
Last night I printed this "Galaxy Purple" vase for Mrs. Mark. When you spin it, the color varies as the light reflects off the different angles. It is thin and translucent, yet water tight. 3 Hours to print.

@klaus said in 3D Printers:
How much does a print job cost in terms of materials? Maybe in $ per hour?
And if a print job goes south, is the material reusable?

$/hour and what to do if it goes south are relevant for both kinds of jobs, blow and print. It would be interesting to see a detailed comparison of the relative costs and benefits.

Mark, I need a new knob for my artist bench.
Could the printer make one that would be exactly like the broken knob it is replacing? Could it be made using black material, and would it be strong enough to work?I don't need a knob, but I wonder if something like an artist bench knob could be made, since a replacement would cost around $40.
Or, you could make cool-looking knobs for snob pianists.
Another Rainman million-dollar idea! -

hmmm. Picture of a knob. I'll look for one.
But let's see. . . If there was a place where you could buy the program for an exact replacement for something, then you sell the digital download, and you make. . .
Another Rainman million-dollar idea! My wife told me that's how she downloads stuff for her embroidery machine. So, it's been done, but maybe not yet for 3-D printers.
