Today I’m printing an object I downloaded from Thingiverse<\/strong><\/a> called the Subdivision Bracelet<\/a><\/strong>. \"subdivision_l_preview_featured\"<\/a><\/p>\n

It’s a particularly complicated shape, and will require a lot of support material. This is a bit of an experiment in just how well my Afinia printer can handle this complex an object, and a bit of an experiment in cleanup, and maintaining sanity, as I’m sure it will take me over an hour to remove all the unwanted plastic from this piece.<\/p>\n

Here is a sample someone printed on the site:<\/p>\n

\"subd_black_preview_featured\"<\/a><\/p>\n

The print is scheduled to take almost five hours.<\/p>\n

Here it is on my print bed, just over half finished.<\/p>\n

\"OLYMPUS<\/a><\/p>\n

Note that while a lot of it is just planes of support material, you can see sneaky little peeks of the design in there, and I’m really hoping this works out.<\/p>\n

I’m printing this for my daughter to wear.<\/p>\n

This may also be a good example of an object to test the acetone vapor-bath concept – which involves laying down a layer of acetone in an enclosed container, with a metal rack sitting above it, not touching it, and the printed part goes in for a given amount of time. The longer it stays in, the smoother and shinier it gets, removing the stepping edges from the part. I haven’t tried this yet, but this object would look awesome<\/em> smoothed out.<\/p>\n

Will post updates when it’s finished, showing the messy cleanup and the final product, I hope.<\/p>\n

Update:<\/strong> Apparently you can design your own complex cell shapes at this website: n-e-r-v-o-u-s<\/strong>.<\/a><\/p>\n

 <\/p>\n

Update:<\/strong> I printed it. Here it is on the print bed, completed:<\/p>\n

\"OLYMPUS<\/a><\/p>\n

Here, I begin the cleanup by pulling it off the raft:<\/p>\n

\"OLYMPUS<\/a><\/p>\n

Then I begin removal of the support material:<\/p>\n

\"OLYMPUS<\/a><\/p>\n

You can see the outer design showing through nicely here. Sadly, however, it is hard to remove the support material without breaking the structure of the bracelet. I counted twice where I had broken a valid part of the bracelet. I can always glue those pieces to re-secure them, but this is a lot of trouble so far.<\/p>\n

\"OLYMPUS<\/a><\/p>\n

It’s at this point, where I have the entire outer surface cleaned that I realize not only do I have the entire inner surface to clean, but the space between the two. There is a space between the outer and inner edges, and all of that is absolutely filled with support material, each little strand of which I will have to remove bit by bit with pliers.<\/p>\n

And I printed it 1cm or so too small to fit over my daughter’s hand.<\/p>\n

As I said. This was just an experiment. I probably will not continue to clean this one. I’ll probably print a larger one and clean that instead.<\/p>\n","protected":false},"excerpt":{"rendered":"
