I've been working on 3d printing an air box to replace the one I made out of aluminum. It adapts a standard intake carb flange to a pair of throttle bodies. Here is a video with the design and several iterations of improvement!

 

Air box bolted on, almost ready for a test!

 

I have no idea how well that would work, but I looks cool as hell.

 

Needs another blower for symmetry.

 

I like how you go through the design and engineering in the video. Thank you for going into all that detail, It is very interesting and informative

 

I just bought a 3D printer, inexpensive, to introduce myself to this technology. Your knowledge is very help full. I have given thought to, if I can mod my printer. I have plans to build a cabinet so I can control the extruder's environment better. My inetrest in 3D is that parts are getting hard to find. Would you consider starting a tread about how use the 3D printer. thanks for the video

 

I completely dig it. Looks like a guy could get into some better flowing injection using more readily available and cheaper parts. 👍🏻

 

Pretty cool, always wanted to get into 3D printing.

a lot of things going on in that engine bay! Looks like a BBC? Looks like coil per cylinder and they look from an LS (round truck coils). I also see a weird setup for brake master cylinders.

 

Very cool! Makes the idea of printing out redesigned TPI runners feasible.

 

An on going discussion about 3D printing would help a lot of folks, I think. A reasons why I bought mine, is too print hard to find interior and siamese runners for my tune port. The possibilities could be endless.

 

Will the plastic hold up to the under hood environment?

 

Do you have a link on where to buy that 3D Printer?

 

To answer the question of temperature, Yes. Some plastics will hold up to about 280 F. Others could go as high as 330?.

To answer where to buy? I bought a TRONXY XY-3 at 3dprintersonlinestore.com They had good reviews and sale price was right. It will do simple plastics and some like ABS and PC. What I did was watch some YouTube views about printing.
Research plastic filament and resins that will apply to your needs. Buy based on what you find. My end goal is to make external engine parts to customize my vehicles. This is based on chemical resistance and 350?. Interior and body are based on UV light and 150?. Hope this helps.
