Can you start a business selling home crafted molded plastic items?

So i have this idea.

1) Use CAD software to design a cool item such as this battery box, or maybe some cool chess pieces



2) Use a 3d printer and print the parts out.
3) Create a silicon mould for all the parts
4) Melt plastic granules and pour molten plastic into the mould and let it cool.
5) Remove the plastic when it hardens and we can sell it on ebay for a profit.

Some may ask why use plastic and not polyurethane resin, since polyurethane resin doesnt require high temperature, the problem with polyurethane resin is that it takes 24-72 hours to cool, at that rate, might as well just 3d print everything.

use ur 3d printers to print more 3d printers then sell those 3d printers you made
Yes, you can try to sell such items on ebay.
Whether you will make a reasonable profit or not will depend upon a variety of factors.
Including: the demand for the items, ebay seller fees, paypal commission, postage&packing costs and the competition from rival sellers within the uk & overseas.
Good luck!
Are you sober this time...? Last time it was part-time porn star.

too slow for large items, imagine you receive a massive order of 100 items, how you gonna 3d print all of them? plastic moulding it is faster
You definitely can, there are plenty of etsy retailers selling home made resin or 3d printed items.
I wouldnt really rely on it for your main income though, but as a side business it could be quite successful
I suspect now is not a good time to be trying to sell plastic anything.

thanks, i have a 3d printer and this thing is amazing!! shamefully its too slow , hence its only good for prototyping. Anything need to be manufactured in a timely manner still need to rely on good ol plastic injection.

But I can buy a pack of storage boxes in Poundland and label them. Might not be 'cool' but cheaper and quicker than sending off for a box. They only sit in a cupboard anyway, so don't need to be decorative.

yea we are talking about custom crafted items not normal items in general

btw i just found this on youtube, precisely what i am trying to do , he combined the advantages of all 3 manufacturing methods , versatility of 3d printers, low costs of resin moulding , and speed of plastic injection moulding. what a hero
