3D printing

So everywhere I look at the moment, I see 3D printing absolutely everywhere, so as part of my Personal inquiry (a sort of research project I had to undertake for my MA, which ends in a presentation of the findings) I chose to have a crack at it, in order to do this I used the imp-like character I used to use a lot for art and illustration (pre welcome to the neighbourhood project).

I then took the simple character sketch and began modelling it in 3D, everything I read about 3D printing stated that as long as the mesh is water tight (no holes) manifold (no open faces or shared edges) it should be fine, there was no mention to ngons or unquaded triangles (sorry for the tech talk, these are things to avoid when creating a model for animation)..

So I deliberately left both of these things in, I kept the model low polygon (it's under 2k polys) and did not equally space the polygons, again this is something not mentioned in any of the write ups I've read about 3D printing and so after an afternoon I had this:

I then took it to see the 3D printing researchers here at the NCCA (who are doing amazing things) and I printed it on desktop 3D printer they have in their lab:

This took 11 hours to print and is around 3 inches tall (i didn't have to be there the whole time, we left it printing over night) As you can see, the structure is there, but that's about it, most detail is lost, partly due to the printer used and the plastic not being hot enough at the start. an unusual wood like pattern appeared on the model too, though unexpected, it has a nice quality to it.
Convinced I could get petter results I sent the mesh to a commercial printing service, who produced this:

The detail is all there, even down to the un-smoothed polygons. this has opened my mind up to all kinds of possibilities. Many people have asked me about sculptures of my work and the main reason why I've never looked into it is because of the spindly nature of my characters, I didn't think they could stand up. when I'm finished with the MA, this will receive a lot of  more of my attention. look out galleries!!

I am very enjoyed for this blog. I feel strongly about it and love learning more on this topic .3D printing, commonly known as ‘Additive Manufacture’ is a form of rapid prototyping where models are made layer by layer without the use of moulds. I am so pleased to get this post article and nice information. I was looking forward to get such a post which is very helpful to us. A big thank for posting this article in this website.

I feel happy to read the blog. I try to learn more knowledge about on 3D printer.3D printing has been around for decades, better known as additive manufacturing (building an object layer by layer). What’s new is that 3D printing has reached consumer-friendly price points and footprints, new materials and techniques are making new things possible, and the Internet is tying it all together.

You are right that 3D printing is absolutely everywhere. It has taken the world by storm since its invention. I am also looking at the list of the best 3d printing pens that can buy for my mom who loves arts and crafts.
