Hey everyone. I have some big news about my current prosthetics project. I have gone and ordered the prosthetic hand from shapeways and it should be arriving in a weeks time. This has effectively been paid for by those who have bought from my shapeways shop, so thank you to all of you.

As you may be able to tell from the above renders I have finally learned how to use Blenders Cycles render engine!

 

Whilst the elastic elements don't yet neatly fit within the fingers this is due to the hand being quite small. As Hollie grows bigger they should disappear in later designs. 

 

You may notice that the tendon torsioners are similar to James Holmes Siedle's design. This is because I re-engineered the idea for use in SLS nylon. I adjusted each block so they sat parallel with the back of the arm to maintain a sleek look. I also made two version of the rotary part of the tensioner.

 

I'll update the blog once I receive the hand. Hopefully it'll be ready for Hollie to start using.

Since I'm based in the UK it's always nice to see local stuff turn up. I also like seeing the digital descendants of my design from two years back.

I notice an interesting tensioner system by James Holmes Siedle. I'm reverse engineering it for Hollies hand since I wasn't happy with the screw version.

I was looking at my posts and realised I hadn't posted an update about hollies hand. This is about v3 of the hand which had some issues that would mean it wouldn't work. I've been doing some R&D on it and hope to have something coming together in the next few weeks. Unfortunately I have freelancing and consulting gigs to find that're distracting me.

I posted the design to thingiverse a while ago.

 

Here is a part of the version 4 hand, which involves fingers and hinges printed all as one piece.

 

For the last year I’ve been working at Hobs Reprographics as a 3D Printing technician. In this role I’ve mostly been taking peoples 3D files and converting them into a 3d printable format, as most programs can’t export suitable files on their own. I then printed them out in either a Projet 660 full colour printer or an ProX 800 SLA printer, and very occasionally a Cubex.

Most of the work was confidential but a few high profile things I can point to are the Manchester MOSI (museum of science and industry) 3D printing exhibition, where I printed… a… lot!

Anyway I learned a lot from Hobs, but as you may have noticed my blog posting had slowed down significantly. This echoed the slow development of what I was doing in meatspace. My main endeavour has been to make a prosthetic hand for Hollie. As I was only able to grab a few hours here or there, and was pretty tired even when I could, the progress was slow.

So I took the plunge again and have decided to set up as a freelance design and a 3D printing consulting expert. This should give me the flexibility to finish what I want to whilst providing an income.

So if you, or someone you know wants to design something for 3D printing then get in contact with me. Or if you’re with a company looking at getting into 3D printing but are not sure if you’d get the most out of it, or which of the hundreds of printers to buy, then again contact me.

I shall be setting up a dedicated website and twitter handle for the design and consulting job probably tomorrow. Pricing will also go on there. I’ll clean up this website and take advantage of some new shapeways apps. I’ll set up some permanent cross linking between my website, twitter facebook etc.
