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.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
