Ok after a lot of research I think im gunna go with the prusa 8" 13 … does anybody here have one or experience with one? Wut do u think?
My first build was a prusa i2. I don’t recommend it. If you mean the prusa i3, its definitely a step up.
a recommendation, all of the threaded rods will need to endure vibrations. Do yourself a favor and use locknuts or better yet, use 2 nuts and jam them together. You may need to cut your rods 2cm or so longer, or you can find half-height nuts. (that was my biggest mistake, not locking the nuts)
My second biggest mistake was the printed parts were PLA. Do not use PLA for the printed parts. Use ABS. ABS won’t get brittle like PLA and wont soften under a little heat.
If you want to be cool like me, look for parts with 100% infill. Some will say its a waste, but you’ll be glad that you don’t break a part if you over-tighten it and it can handle even higher temperatures.
100% infill isn’t a total waste. The added mass ensures that it takes much longer to heat up and thus won’t be prone to melting as easy. That’s actually how so many people have “gotten away with” PLA, by a high density fill.
Good call as the prusa’s have an incredibly sized community that have already had the problems you will encounter. Are you buying a kit a presume?
What is a prusa 8" 13? Is that similar to the i3 or an earlier version?
I’m sure it was a typo and the guy meant i3.
3D printing motorcycle fairings is the wrong application for these types of 3D printers. You need to step back and reevaluate your need for a 3D printer and it’s actual use. You’re on the hype train to nowheresville and are probably just wasting your time.
The speed required to print a fairing in less than a week would be astronomical.
And changing a printer to that size would require a complete redesign.
Buy a bunch of Styrofoam blocks, carve out the shape, and use fiberglass.
I bet you could get a fairing or half of one out of one of the deltas expanded vertically…
I wouldn’t really trust the materials for use as a motorcycle fairing. You might be able to make forms, put gel coat on it and lay up fiber glass into it. Not that good at this process, so I could be completely wrong. Either way, size would present a huge issue. It’s probably much cheaper to buy an after market fairing, despite their high cost
Theoretically he could use a large nozzle to speed things (like the MIT one that can print chairs) up or use some other method like this: http://www.webpronews.com/objet-makes-a-huge-3d-printed-wrench-just-because-they-can-2012-12
But I agree that printing motorcycle farings is an expert type activity, not something to be attempted until you build a normal sized one, and probably could be done with a more conventional approach.
