So my Compass broke last season, so ordered another but different one, but was just a tad too small to fit in the hole, so made a CAD of a new mounting and 3D printed it!

If anyone has hard to find broken plastic bits or mounts ect that you cant buy off the shelf, pop me a shout and ill knock one up! (providing its no bigger than 20 x 20 x 20 cm!)


Finally going boating tomorrow, Dartmouth here we come!!
 
That is a very cool solution, nicely done. What's the printer, and what modelling software do you use? I'm interested in the whole 3d printing thing but know nothing about it.
 
can't beat a bit of 3d printing. Hopefully it will come on leaps in the next 5-10 years. Out of interest which printer did you use? been looking at getting an ultimaker 2 but think i will wait for the next generation

Jimmy, I'm joining the Manufacturing Technology Centre in a weeks time, and amongst many other toys, they have several 3d printers and proper geeks who understand them, so should have access to knowledge fillers. Might be worth a visit if ever in the Coventry area?

ohhh, any chance of tagging along? We want to start an Additive manufacturing competition for our Apprentices and I am currently looking for inspiration to help push some out the box thinking.

Yep, let me get my feet under the table for a couple of weeks, and I'll see what we can do. The whole ethos of the place is to improve manufacturing in the UK, large companies and SME's.

Fantastic. As a National Apprenticeship Ambassador I am always looking to expand my contact list and find new ways to inspire the next generation of engineers.

Apols for the Fred Rift, but you sound just the sort of org that we need to be dealing with. We have an Apprentice Academy, and take on a significant number every year.
 
I have the Velleman K8200, comes in a kit form so you have to build it. Its great as you can customise it to the hills. I have only had to add a glass plate and its all good! Use Mattercontrol for the printer and Solidworks for the CAD. Its actually my current job as a CAD designer so if you need any tips please pop me a shout! solidworks is probably a little bit ott for most people, Sketchup is just as good for most things in all honestly, allbeit a little simple!

Its only going to get better - but its not as new as people think - been around since the 80's! the main difference is that the material I use is around £15 for a kilo, where as a big company like stratasys (bought out by Objet i believe) is around £250 for basically the same stuff.

The real klincher for me will be when metal 3D printers become affordable. the ability to print working parts is going to be a game changer - but at the moment their half a mil for a small one!! :s
 
Ahhh thought so...I bet these guys are having a bit of a tough time with all the smaller much more cost effective PLA printers coming out!

Thanks! its really useful having the kit to make bits and bobs cheaply - probably cost around 80p for that print!

I use the cheap of the cheap £15 filament from ebay - printed on to a heated glass bed, with masking tape. No curling issues at all but can be a right bugger to remove! I have some flexible filament too - not ninaflex but seems to work fine, albeit verryyyy slow!!! otherwise the filament bends before it gets to the extrusion head and jams. its almost like the flexible stuff is melting through the extruder by gravity rather than being pushed through like normal pla.

the other thing that could be useful is apparently some have converted my make of printer into a CNC mill - why not i suppose, with a 200mmx200mmx200mm bed i bet you could almost make an engine mount ect out of it...!
 
The smaller printers are great, and are certainly movingthings along at quite a rate and bringing new users into the market
As for impacting the larger companies, bed size is always the issue with thesemachines, companies like maintenance contracts and guaranteed material supplies.
I’m told that coating the glass with pritt stick removesthe need for the tape (I’ve never tried it, I don’t use the extrusion printers).Apparently a few minutes in the freezer with thermal shock the part off theplate, or a soak in warm water will dissolve the glue.
Having a mill and a printer would open up a lot ofmaterial choices :)

Spoke to a mate about this, you need to extend the head up to the feed mechanism to bridge the gap and support the filament, then you can print faster.
You can buy heads designed for this, or there are designs on the web (not sure about your head) so you can print your own
