Is it illegal to sell 3D prints?

To begin with, it’s totally safe and legal to sell your 3D printed parts on e-commerce websites like eBay, Amazon, and Etsy. People are making a fair living offering their printing capabilities on different platforms.

Is 3D printing as strong as injection molding?

Yes, injection molded parts are stronger than 3d printed parts. Usually, if we ship 3d printed parts to our US or other country customers, we use a wooden/plywood case to protect them during transportation.

Which is cheaper 3D printing or injection molding?

Injection molding is cheaper than 3D printing if you produce more than 100 parts. While the cost per unit using 3D printing stays relatively unchanged, the price for injection molding becomes dramatically better the more pieces you manufacture with your mold.

What are the benefits of 3D printing compared to injection molding?

For lower quantities, 3D printing will offer a lower cost per part, since the cost of the mold is factored in and isn’t spread among a higher quantity of parts. As volumes increase, injection molding becomes the more cost-effective solution, as more parts are produced against the one-time cost of the mold.

Is molding additive manufacturing?

In summary, all three types of manufacturing processes (additive manufacturing, a.k.a. 3D printing, subtractive manufacturing, a.k.a. CNC machining, and injection molding) are most effective for certain phases of the prototype production process.

How does plastic injection molding work?

The injection moulding process involves heating & injecting plastic material under pressure into a closed metal mould tool. The molten plastic cools & hardens into the shape inside the mould tool, which then opens to allow the mouldings to be ejected or removed for inspection, delivery or secondary operations.

How do you do injection molding at home?
