That's a good point. "Up to" can be great qualifier to exaggerate.
Printing children's product is problematic. There are scores of regulations for reasons. Making children's toys from recycled plastic is nice and trendy but not very safe. For example, it would be almost impossible to know if the toy is BPA free. Anyone giving them away as gifts or selling the item at a DIY/Makers Fair could get into trouble for endangering children.
Color me skeptical with the quote of "an average household could save up to $2,000 a year making their own plastic products at home". I guess that the "Up To" clause covers them, but I really don't see many households purchasing $2000 worth of plastic products a year which can be printed at home!
3D printing is no doubt a greener technology , less energy is required in this process which in result produces very little carbon dioxide which is harmfull to the enviornment . I have read somewhere that people are using filamaker that is a machine in their homes with 3D printers that takes in used plastic and releases fresh strings of plastic.
Thanks Ann, for such an informative post , According to me 3D printers used for personal use will be more cost effective as compared to those used for mass production because less raw material will be used. The example that you mentioned in your article regarding children block makes it very clear that 3D printing can be cheap because when we make objects by orselves we can chooe the type of the product , traditionally such blocks are made of wood but we can make them with plastic making them partially totally hollow from inside this reduces the material and drop down the cost of manufacturing as well.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
