Our September Hacker of the Month, Oliver Vaughan-Jones, is an outside, snow-sports fanatic that comes from a design engineering background in central Wales.
Oliver began his journey into 3D printing early – his father was a dentist who used 3D design and printing to recreate jaws and dental molds for his observe. Seeing the advantages of the expertise early on, Oliver was already aware of the ideas and functions of 3D printing when he enrolled in Brunel College in 2008 to check design engineering. Oliver additionally labored as a snowboard teacher and was very keen about snow sports activities.
Throughout his third 12 months, the scholars had been tasked with making use of for jobs that had been related to their diploma programs. Right here, Oliver landed a possibility working with Gillette’s analysis laboratory close to London.
A few of Oliver’s sketched designs for the sit-ski
Oliver explains, “It was there, as idea engineers, we got here up with concepts, designs after which used a variety of 3D printers and stereolithography to create revolutionary idea razors. The truth is, again in 2008, the analysis lab already had a division of 4 or 5 workers devoted solely to taking the CAD recordsdata from the designers and making their prints for them – what luxurious!”
However throughout his time at Gillette, Oliver turned extraordinarily in poor health and was identified with myalgic encephalomyelitis (ME), a neurological spectrum situation that may have an effect on individuals to various levels. Oliver was hit extraordinarily onerous by the situation, and he has spent the final eleven years bed-bound nearly 90% of the time, and he usually has difficulties with considering and focus. However Oliver is greater than his situation – beneath every part, he’s nonetheless a design engineer and a snow-sports fanatic at coronary heart, and he’s on a mission to make hitting the slopes a actuality for others who share his love of the mountains.
Cardboard mock-ups of some sit-ski components
Decided to make a distinction for himself and others, Oliver began portray in 2017 to lift consciousness of ME in addition to funds – 20% of the gross sales of his work go to analysis right into a treatment for myalgic encephalomyelitis. As soon as his paintings gained some traction, he was capable of transfer ahead along with his subsequent purpose: designing and making a sit-ski; an adaptive machine for many who can’t stand, however nonetheless have upper-torso mobility, that may allow them to shred on the slopes once more.
As soon as he began, he found that a lot of the present gear is extraordinarily cumbersome and prohibitively costly in lots of circumstances. He felt that he may do a greater job at designing a lighter, extra inexpensive sit-ski regardless of his situation.

So for the final eight months, Oliver has been designing an adaptive sit-ski from scratch, principally from his mattress. Oliver began with sketches to idea his design and rapidly made life-size fashions for cardboard cutout fabricating. On the identical time, he took to YouTube to discover ways to use Fusion 360 so he may begin to 3D print his cardboard ideas. Oliver’s most important design targets are to develop a platform that has a extra user-friendly worth level, is extra adaptive to extra customers, in addition to extra light-weight from a supplies standpoint.
Oliver explains, “There are lots of concerns; rider weight, rider skill-level, ski-lift entry, materials picks, materials thicknesses, and shock absorbers to call a couple of. The 3D printing is permitting me to mannequin my concepts up rapidly to see if the mechanics work and, extra importantly, the ergonomics. For instance, some individuals could be lacking limbs or have buildings like prosthetics that should be accommodated. Dexterity is one other main consideration; poor gripping power is a matter for me and I would like to incorporate buttons or straps which can be straightforward to find and use. Like all design work, it’s juggling many components on the identical time and attempting to deliver it in underneath funds. I’ve already modeled a full-scale prototype and I’m aiming for a completely practical prototype by November. Nonetheless, the easy purpose is to have one thing I can journey on! I’m outpriced to purchase a ski outright and leases usually are not attainable. It is a ardour mission for me and I can’t wait to journey this winter!”

Oliver is at the moment working with a Creality CR10S Professional and a Flashforge Dreamer to create his 3D prototypes. Oliver gained worthwhile perception into every part from mattress leveling, altering the belts, the nozzle, the hotend and plenty of different sides of 3D printing utilizing the CR10S. Nonetheless, his favourite printer is the Flashforge Dreamer, because it has been extremely according to nearly each materials he’s thrown at it from PLA to ABS and nylon. He additionally makes use of simplify3D as his slicer because it provides nice management over slice settings and contains a big selection of suitable printer profiles. Proper now, he’s trying to find a steady 3D printer with a bigger mattress to accommodate the bigger print quantity he’ll want for a few of his prototype components. His overarching purpose, as soon as his prototypes have been examined, is to manufacture usable components with NylonX for excessive power and sturdiness.
A conventional sit-ski in motion
Like all designers, Oliver hopes that 3D printers and supplies will proceed to come back down in worth to make extra complicated functions obtainable and inexpensive for everybody. “I’m effectively conscious of how very new I’m to 3D printing and I don’t have nice information or expertise in it past the home sub-$1000 vary so far as equipment goes. It does nonetheless really feel like far more of an artwork kind slightly than a science to me. I think about home printers of the long run to take over the laborious duties of correct automated self-leveling, nozzle cleansing and to have higher sensors so when issues begin to go incorrect, they will self-regulate. I feel we’re going to see bigger print volumes come onto the market imminently and having simply been despatched a pattern from a steel 3D printer, I can see the long run in a number of materials printing with completely different supplies being printed inside one print (complexities like shrinkage charges for every materials calculated beforehand). Past that, I think about one of many subsequent main leaps shall be some type of printed circuitry which shall be integral as a part of the design.”
We’re extraordinarily excited to see the finished sit-ski that Oliver is designing, and we hope that the usage of NylonX within the design makes it probably the most rugged sit-ski in the marketplace!
