/diy/ - Do It Yourself

[Anonymous No.1215586]

i gotta fabricate a couple plastic parts. Or at least approximate them for a prototype.

they're too big to get 3d printed at a reasonable price. I'd like to machine my own molds for injection molding. I live near a TechShops and I took classes on it, but i wont be willing to pay the monthly fee for a while, and I dont want to put this all off and lose momentum.

It's this and another thats basically the same but inverted to fit around the lip, and no disc in the middle.
Is there an economical and fast solution that might produce better results than just slicing up PVC pipe and gluing it all together.

If it's too expensive to 3d print it's too expensive to inject mold unless you have access to an industrial injection molder. Small ones will inject like 11g, basically trinkets

If cheap is the name of the game order some plastic pellets or recycle some grocery bags. Cut up the grocery bags and bring some mineral oil (baby oil is cheap) up to melt temp but below flash. Figure a way to make your sacrificial mold so tolerances are acceptable

You could machine it. It's still be slicing up PVC and gluing together, but with precision.

if you think it's too expensive to 3d print it will be way too expensive to injection mold unless you need like a thousand of it
from the looks of your model just buy some pvc pipe and put on a custom 3d printed end-cap

Is that a dildo or a pipe bomb?
