Replica DB4 Project
...or at least very slow progress at the moment. Finding it hard to find time now that I have to drive out to do anything on it. Things will pick up again when I'm in the new house and it's back in my garage (Sept)
With pleasure watch your project. Inspiring!
Good luck! Forward to continue ...
Regards from Ukraine!
hello mate, what your doing is absolutely incredible. wish you were more of a Mclaren F1 kinda guy though =P. anyhow, i gotta question, if you were to start over this project, what 3d printer would you use?
Probably the same, you don't really need a bigger one as you want to keep prints to about 8 hours so you can get in 2x per day (to limit the time and material loss of the few failures that happen from time to time) and you don't need it to print at a better resolution as you need to apply body filler & sand it back a few times anyway. The only thing that would be worth spending money on is one that prints quicker but I'd still problably get the cheaper one as I'm in no particular hurry. This guy's done an F1 might be able to get him to do you a shell: m.autoblog.com/.../
Any progress in the build?
No sorry, house is taking frigging ages to build. looking like july now
Yes, any further progress? Looking forward to seeing the body come together...
Looking like july now, I'll get there eventually
I am tossing around the idea of doing something similar though a completely different vehicle...
I have a few questions though.....
I assume you are printing in ABS... and I know that Bondo (body filler) will bond to ABS... but couldn't you also just fiberglass over the 3D print with enough layers to create a thick enough body wall?
Or is the end game going to be taking it all apart....making molds... and producing more than one????
Keep up the good work.... I am sure I will have MANY more questions...
Thanks, I don't know if that would work, even though the printer prints to .3mm those bits when stuck together (especially the flatter parts of the body) need a lot if finishing work and bondo is a bit easier to spread where needed and sand back than fibreglass.
Then there would be getting the body off, you would have to finish with bondo to get a smooth edge to then sand fine enough so you could detach the fibreglass but then there's the issue of the details like vents, bonnet scoops etc (unless you dismantle it from the inside?)
You'd then need to do it all again with a gel coat to get the outside of you fibreglass body looking right at this point the body a bit larger and you might have difficulties with the glass fitting, you could scale down the original build but it'd be guess work on how much
Creating a mold instead will require more finishing work (it's easier to finish the plug than fix issues in the mold) but when you make the mold you can split it up into whatever bits that allow for easy release and the gel coating goes on the surface if the mold so requires no rework (not much anyway) and you have a mold you can sell or make more shells if you want
Hi there! I was thinking, you're going to 3d print a "buck", cover and finish it with fiberglass, then make a fiberglass female mould, and then make the actual parts from there.
But couldn't you just 3d print a base for the female mould, then fiberglass the inside, finish it, and then make the final parts? It would save some time?
Also, what settings of layer height and % infill are you using?
It's quite hard to finish a female mold, much much easier making a flawless plug to take a mold from. I'm printing .3mm so it's quite rough but 3x faster than the high res option 20% fill but the thin prints (5mm) have 2x 1.5mm? walls so the fill ratio must be much higher
Has this project completely fallen thru now???? I haven't seen any updates in a VERY long time....
