A $1,500 hand-operated, bench-model plastic injection machine funded via Kickstarter can be used to mold small, quality, plastic parts inexpensively, on demand. Shown here is the prototype with the basic manual (screw tightening) mold vise that comes standard with the machine, for prototyping or lower-volume production. (Source: LNS Technologies)
Since 1968 Morgan Plastic has made handy little presses for engineers and small manufacturers. See: http://www.morganindustriesinc.com/ You can buy them on the used market for little money. For years we used parts from these presses when large production was impossible.
Thanks, Al. This made me think of a Gadget Freak article in reverse: what would happen if one of our many innovative, creative Gadget Freak inventors had gone ahead and commercialized his/her invention and sold it? I've noticed reader requests for exactly that on some Gadget Freak comment boards.
Do you remember when you were a kid; there were two examples of modern industry at the Zoo? One was the little coining press that took your copper penny and rolled it into a coined medallion; the other was micro injection press that molded a little bear as a souvenir in front of the Polar Bear house. For a Quarter, you watched a little mold-press produce your bear. I still remember the smell of molten polycarbonate I smelled for the very first time.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
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).
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.
