I have been experimenting with an Ultimaker 2 printer and here are some of my initial results.
At this point, I have been working within the limits of the 3d printer software, which seems to crash when trying to generate print paths for highly detailed meshes (>50mb) or complicated forms that have a lot of overhangs. For this set I've stuck with relatively flat and contiguous surfaces.
Overall I'm pretty impressed with the level of detail the Ultimakers can generate.

Wait, are these actual photos of your 3D prints? They look more like compute-generated images.

Otherwise, I'm also very interested in the possibilities of 3D print, so let's continue this discussion.

yep. part of the effect is due to the back-lighting coming through the material. (the yellowish glow) While there is still a lot of detail in these fractals, they are substantially smoother than the original fractals due to the process of preparing the mesh for print. I'm sure others have struggled with this.

If you look closely you can see a lot of the printing artifacts like the print paths, little leftover hairs where the print nozzle retracted, and support material which hasn't been totally removed.

Happy to keep this discussion going  smiley

really looks great! could you post a full view of the printed objects?
It's so hard to tell the size of it.. (soo uncommon for fractals wink)

Many people make photos of their 3D prints with things like matches or coins in the pictures, so you can tell how big things are.

Fantastic result I must say, ansr23, and welcome to the forum!
- But I am even more amazed about your photographing technique, how did you get that yellowish back-lighting to look exactly like iteration fog?  shocked

Ok. Here is a pic with a banana for scale.


No photography techniques..these were taken on my phone actually. The glow is just how the light passes through the print material.
I am purposely cropping these images to not show scale, and because most of these prints are "cropped" captures so they have hard edges. I am more interested in surface detail; they are not as interesting as sculptural objects. I am thinking of mounting these in deep lightboxes so that they can be back-lit. A lot of the internal details show through this way.

The print in the image is around 200mm x 200mm x ~150mm which is the biggest size in xy that i can print on this particular printer. I'd love to do larger stuff am looking into cnc routering these into wood.

Wow, to be honest I thought they were renders... and that is good smiley
Great work!  A Beer Cup

I totally understand that! those details are beautiful!
this sounds like you print them yourself, at home?
that's exciting! what equipment did you use to print? I mean, is this like a potential hobby to start?

Thanks for your kind words.

I am fortunate enough to have access to some printers at a fabrication shop at a university.
I would love to have my own printer at home  but they are unfortunately a little out of my price range.
Also there are tremendous improvements made to the hardware all the time that they become outmoded pretty quickly

I think anyone producing a lot of prints through services like shapeways might eventually make their money back.
However these are desktop printers and can not come close to the quality and material options that commercial printers produce.

Here is a pic of a print in action. All of those horizontal lines are support material which is removed afterwards.

This is truly great. Sorry I couldn't believe you at first - the pictures simply looked too good.

Nice fractal modelling for food made!

Sadly that 3D printers are too expansive, that I like to purchase one, for to decoratings.

Here are some details from my latest prints.

I've had a little more success with complex 3d forms using bulb tracer. Meshes come out pretty clean and don't crash the slicer software, although 50mb stl file size still seems to be the upper limit at least for Cura and Simplify3d. Not sure how large a file shapeways accepts. These prints are about 150mm x 150mm x 150mm and print at a resolution of .01mm. Base mesh is exported at 800^3 voxels

Here are some pics of new prints. Removing the support material from interior spaces has proven quite difficult if not impossible for some of these.







Here is a collection of some my prints so far...
