Hi, first of all, big thumbs up for the easy composites team. Great tech. support, youtube, wepshop etc. you got me into trying carbon fibre. Well done!
I'm new to carbon fibre and just wanted to get some tips and tricks from more experienced doers. I have vacum bagging equipment and have been doing a few test just with plates on glass to get a grip on laying up wet and mixing epoxy, vacum, bagging and so on, I did one intake tube (not one a really need) just to learn and see how difficult it is and how to not do. I have a 3D printer so I will print molds and coat them with XCR epoxy+relese, the same way I did with this test tube mold.
What I learned was that you cannot do anyting with the inside of the tube if I put the bottom half on the table and then the internal vacum tube through. And thats ofcourse totally obvious after you have done it once  , could only get the peelply on one half as I needed the CF parts to overlap and so on and so on...
   
But to the real project, this is what I want to build. A modular CF intake, that are in three parts + aluminum flange + throttlebody flange in alu. Three parts so I can make different lengths of runners and different size and shape of plenum depending on the case.
I was planning to bond with structural adhesive as you see with over lap of 7-10mm. Planned thicknes is now 2.5mm, is that overkill?
 
Any comments and thougths on bonding points and thicknes of the part?
When split in this way its also more easy to wet lay parts. maybe I'll try infusion later.
Anyone aware of 3D printer filament that can take the prepreg heating process?

if your printer is capable of printing ABS, that material will remain stable up to 105c. Could suffice for a low temp/variable temp cure/post cure.
