Casting Polyurethane Motor Mount Bushings with Liquid Urethane & 3D Printed Mold (Scion tC2 / tC2.5)

[@SakeBarSushi]

As I am watching this I am 3D printing a custom gearbox mount for my Volt. I am using TPU 95A with 40% hexagon infill and 5 shells plus 5 bottom and top layers. I just did a web search and it seems that TPU 95A may have not been available at the time of this video. It is amazing how 3D printing has revolutionized the DIY engineering scene. Great video!

[@EnergeticWaves]

Isn't it fun all these great toys they invent for us to play with.

[@VampyreX13]

It's very handy. My girlfriend and I are thinking of getting a laser next and possibly a resin printer for future (non-car related) projects.

[@emailformosa]

You can use PVA (which is a water soluble support filament) to print the molds. After casting you can dissolve the mold away from the casting with water.

[@drrock5356]

Another good variable to check is how much the engine moves when you load the drivetrain. Pop the hood, start the car and put it in drive (in an automatic), but hold the brake with one foot, and give it some throttle (so the car doesn't move!). Note how much the engine rotates as it revs.

[@-smp-scientificmethodpersp838]

This is the coolest method I've seen.

[@wizrom3046]

You normally dont need to destroy the moulds, just squirt some compressed air down the sides and the rubber part will pop out. If it is hard to get down the side drill a tiny pinhole in the bottom and squirt the air in the pinhole, then the pinhole can be covered witn sticky tape for the next mould use.

[@VampyreX13]

The mold would definitely need to be printed thicker for that.

[@95TurboSol]

Have you ever tried printing an 80A tpu bushing instead of using the molds and stuff? I modeled all the bushings on the EG civic and del sol and put them on thingiverse for people to print but I don't have a printer yet so I don't know how well it works.

[@VampyreX13]

Since I originally posted this video, I have 3D printed bushings, but not for the engine mount. I replaced my upper rear shock bushings with 95A ones since I have a strut bar bolted directly on top of it.

[@jasonriley8977]

Hi if you drill a small hole in the bottom of the mould and use compressed air they’ll remove much easier

[@VampyreX13]

Thanks for the tip!

[@nickstewartroc]

Thanks dude, this is great! Subscribed

[@kush_tography7960]

I know this is an older video but the poly set up like that because of the 170 degree temp. I'm surprised the can even suggest to get it that hot. The hotter you heat it up, the faster it sets up. I would went with about 150. Also, if you have an air compressor, those will pop right out the mold with a little air blast.

[@VampyreX13]

It's my first time working with the stuff, so I was just following the instructions as close as possible. You're the second person to recommend using an air compressor, which I do have. If I have to make more in the future, I'll remember that.

Hey great vid do you have somewhere we can talk business I’m looking too pay you for fabricating mounts for my car if something your interested in please let me know

[@BedazzledChanclas]

This is pretty badass

[@cobra3289]

When you have a bushing, its much easier to make a silicon mold from it, much less work, the 3d printer is for making master pieces.

[@Kevin-im2ri]

If it melts back down in the oven at 170 wouldn’t it soften also while sitting under a engine at 160-260?

I’m waiting for that original filled motor mount video and results. I don’t know if you are up to making it a business but I would buy a new one done from you. If any other viewer are up to buying them please reply to this post so we motivate him selling them to us.

[@VampyreX13]

I just need to edit it together and then actually swap in the mount to test it, but I've been busy this week. I promise I'll have it up soon. As for selling them, the only issues are that I would need to test it to make sure there are no issues and I would need a mount to fill. Also, you need to use the entire contents of the can of urethane to have the proper mixing ratio, so that would be a huge waste for one mount only.

What is the benefits of polyurethane exhaust mounts?

[@VampyreX13]

They don't sag and they prevent the exhaust from bouncing around. They're great if you need the exhaust to sit in one spot to avoid hitting the bumper or anything else. If I didn't have them installed, my muffler would bang on my trailer hitch all the time.

[@zacharyohare2118]

Motor mounts are really large, but I'm hoping to do this with differential bushings for my SRT8, then move on to suspension parts as well. Freaking k member bushings are $200, diff are $150 etc, just ridiculous by the time you replace all the the link bushings and such. Car is multilink front and rear, probably 30 bushings, averaging $25/bushing or more. Yuck. can replace the entire arm with rubber bushings for that. Here's an idea I'm curious if you're interested in trying- what about casting an insert for the oem motor mount, other subframe mounts etc, IE how torque solutions does it. That what you don't get much extra NVH until it starts to deflect significantly.

[@VampyreX13]

I thought about making inserts, but I think it's just better to fill the stock mounts once you trim out some of the extra rubber per kzbin.info/www/bejne/eqmkfWWkbLung7c. I don't have any issues with NVH with my mounts.
