Copy of a wooden cat .
The original carved in Florida Cypress. 6" in height. Was found in N America. It was many years old and discovered in late 1800s, but don't quote me. LOL

Can I quote you to agree you've got it dead right (as far as I know) :shock: and you've certainly captured the detail for the experts to examine. :greennod:

Thanks Pogue.
I had to look up the detail :shock: :smiles:

Very nice. I'm presuming this is another 3D printer masterpiece? How does it work?

Well Gandalf,
It’s printed using 1.75 mm diameter plastic filament on spools.
A f3D FILE IS CREATED BY SCANNING THE SUBJECT. This is then put through another application which “Slices” the model and produces a file that can be read by the printer.
The plastic filament is fed through a heated mozzle/ at 0.4mm.
This moltem plastic is laid down on a heated base.
The heated base moves back and forward.
The print head moves left and right and up. Controlled from the onboard computer. Thus giving X, Y and Z axis.
Thus laying layer upon layer of plastic. The plastic filament comes in all shades of colour.
This is the rig I use. The reel of filament is on the right as you look at it.
The layer can be set from 0.1 layer up, but 0.2mm is usual.
All settings can be changed.
Hope I have not gone too far and am teaching granny to suck eggs, as they say. ;thinking:
One can also use your camera to make 3D models. Photogrammetry. I think it's called. Not tried it yet.

Great information indeed and it took the machine how long to finish the job.

Hi Bob.
It took sixteen hours to finish the cat.
Not a quick thing indeed. Some can take a lot longer depending on size and printer settings.
:shock: :) :)

WOW!!! Had no idea it was so technical. Did you already have a model of the cat to scan first then?
Are the necessary plastic threads etc expensive and easily obtainable?
:clapping: :clapping: :clapping:

Gandalf. no did not have model of the cat. The Smithsonian and British Museums publish some 3D model files free to use. The cat model file is from the Smithsonian.
The Groot model was a scan of a model I have.
The plastics are readily available. I buy mine from Amazon. The cost is quite dear. relatively speaking at about the £20 for 1Kg reel. That should bee sufficient for 6 or 7 prints depending on size. My printer limit is 205mm high and wide.
Since the prints take so long I have a simple web cam set up to enable me to monitor the print. If the print fails, model fails to stick to the base plate one can end up with a birds nest of plastic spaghetti. LOL
There are different types of filament that one can use if the printer allows. Some are bendy.
I hasten to add I'm very much a tyro in this vemture. :err: :D :D

Well I think you are getting some splendid results :clapping: :clapping: :clapping: :clapping: :clapping:

Your explanation is better than anything I have read in the past.

That is fascinating stuff, Skeeter.
What can be accomplished with 3D patterns must be almost limitless.
Thanks for sharing.
