I have never made one from carbon fibre, the fibre glass is more affordable, if you want a carbon fibre enclosure you will probably need just: Mold (with rounded edges), Crabon fibre cloth, Epoxy resin, gelcoat, catalyst, Separator… To make the enclosure clean and nice like in the posts below you would probablyneed a vacuum pump…It can be done with a simple hand lay up, but i wouldnt do that with carbon…Maybe someone more experienced might help you more…
For an inspiration seach forum…
That is great. But i think i will make it with 3d print 100% infill and then add carbon layer on top. The items are really expensive in Denmark where i live.
you can check my build. I’ve designed and printed dozen of enclosures in PETG. I’ve used a layer of glass fiber on the inside to reinforce them. Never go for 100% infill. Not even 50%. It’ll take up all the flex and structure to keep it rigid and tough… Post finish it with a heat gun to get the layer adhesion done.(kinda like annealing). I’d also go for min. 4mm wall thickness to get some infill in the wall too.
It’s a great build. I can’t however find the stl files. Where can I get them? And how did you get the surface so smooth with 3d print. And what thickness material did you use fr coatin
How can i find the curve of the longboard so i can make the right 3d file
lay a straight edge across the top of the deck, measure from the bottom of the straight edge to the top of the deck. Example, a 3/8’s measurement means you have a 3.8’s concave.
For folks thinking of 3d print and then adding CF/GF layer on top - just make sure it’ll stick. Most epoxy won’t stick to plastic. I can see using a 3d printer to make a mold, then using the 3d mold to layup your CF with vacuum for nice finish… but sticking directly to most plastics - i think it’ll separate too easily.
@MasterCho - the CF guru - can you confirm?
Do you know if this will work? Hobbyking says it will work.
If you want to do CF/GF - don’t use epoxy glue - instead use a real epoxy intended for CF/GF. Thinner to “wet out” the fabric - not glue. My favorite (but most expensive) is West Systems 105 epoxy, and 206 slow hardener. I’d look for less expensive epoxy options in your area, but these are the top notch ones IMO.
Do you think the one from hobbyking can be used. The one you recommnd is way to expensive for me
All epoxy resin aren’t manufactured equally but one that I used sticks really well to PLA. Please make sure to clean the surface well before applying and I recommend using vacuum bagging which removes trapped air, compacts the fiber layers and reduces humidity.
glue won’t work well. Can you get it to stick - maybe… but it won’t “wet out” correctly - saturate the cloth and get the fabric to stick together into one solid piece. You’ll likely have a thicker consistency w/ the glue and it’ll be “splotchy” with bubbles or voids which will make it weak/fragile or simply not work at all.
There are a ton of epoxies online - I don’t see where you are located to recommend one close to you (nothing noted in your profile Oliver). Jamestown Dist/Totalboats has a less expensive option.
I’d also look on amazon for a small amount that is intended for CF. I see some 6/12oz “kits” that are about $20-25 shipped for me in the US.
You might need more than 15min to work on.
Thanks MasterCho! I didn’t know PLA would stick - that’s great to know. What epoxy do you use?
As it seems like @nikoli280 is on a budget - i’m betting vacuum is out of the equation due to cost. I’ve done both and found for a simple shape - some foam and weights can do a good job compressing the layers to help instead of vacuum.
@nikoli280 - read through:
I have been using easycomposites and West Epoxy System works great too.
fiberglas might not stick to the 3d enclosure you might need a primer but you could use the 3d printed enclosure as a mould for the fiberglas enclosure,
Hi thanks all for replies. I liv in Denmark so some items is hard to get. I will look at the guide without vacuum. I’m on a budget. I really like the boosted board look and would like to rein act that. But it’s also hard to Ger good models. I have ordered both carbon fiber and glass fiber with 200gsm.
But as I can read, it can be difficult to use the 3d and carbon fiber together. If I can do the molding techniques then I think I will. But glue is difficult to find. Do any one know some good resin in Europe?
Denmark and boats - any marine supply should have 2 part epoxy resin for fiberglass and carbonfiber repair!
it’ll be more $ than buying online, but with your 25% tax added on, perhaps not as bad!
GL!
I’ll try thanks
What about printing Nylon? I think it might be a good option.
Adding fiberglass makes the process unnecessary complex to my opinion. I would rather ad some protection material in the inside of the enclosure if required.
Also baking PLA after printing ?
