Ann- thanks- I did search per your advice, and found this:


,,,which opens a whole new paradigm for me. Very thought provoking and encouraging for new innovative methods for everyday things. (Too bad the associated comments under this linked story are so negative and narrow minded - it helps remind me that even break-thru progress has anchors to drag.)

Jim, so glad to give you info about something new that sparks your creative thinking. I think the potential of 3D printing technology can be applied in all kinds of ways we haven't thought about yet. I really enjoy doing that here at Design News. I don't expect everyone to agree or find what I write about interesting. But I'm glad that many enjoy the new and different technologies I find. Creativity has sometimes been defined as bringing together disparate elements in a new way.

I am also impressed with the forward thinking ability of this South African consortium to strategically invest in processes that produce net shape titanium rather than raw titanium, thus capitalizing on much higher profit margins.  This vertical business integration will help both their organizations and their country.

Greg, I agree, and I thought Dave's comments were also to the point regarding vertical integration in South Africa all the way from raw materials to exported products. Looks like a very wise business move for the country overall.

Excellent article Ann.  I have followed "additive manufacturing" over the past few years and remain fascinated by the possibilities.   Right now it appears the various types are as follows:

·         (SLA) Stereolithography

·         (SLS) Selective Laser Sintering

·         (FDM) Fused Deposition Modeling

·         (3DP) Three Dimensional Printing

·         (Pjet) Poly-Jet

·         Laminated Object Manufacturing

Stereolithography, of course, was the very first.  There are two things that really amaze me about the processes: 1.)  The size of manufactured product grows each year and 2.) The materials used for the each method expand and grow each year.   I would not be surprised at all is the testing planned yield components that "make the grade" as far as specifications.  I suspect they could exceed expectations.  Again, great post.

bobjengr, the number of AM techniques is actually pretty small. Basically, there's SLA, (S)LS, and FDM. Various forms of "3D printing" ("3DP" is a term invented by MIT), are simply doing AM with an inkjet-type nozzle that sprays material in all three directions (X, Y, Z) for creating layers. PolyJet, for instance, is not a separate method, but an SLA technique using inkjet methods. A caveat: the term "3D printing" is now used, confusingly, to refer to all types of additive manufacturing. You also listed Laminated Object Manufacturing, which (obviously) uses lamination. This is a rapid prototyping method that competes with SLA and SLS, but is not considered an AM technique.
One of the best AM resources I've found is here:

My company Control Systems Technologies, LLC holds four patents in modular robotic technology.  We basically form a multi degree of freedom configuration (synchronous 6 DOF) around an application and thus shape a work space according to a customer's need.  Our path planning program is based on an API that is directly tied to SolidWorks thus enabling the user to form a 3D path within minutes (including cladding paths) to be executed on an existing part and/or slicing if the part needs to be built.  I think that this technology can be applied readily in 3D printing applications.  Please let me know who I may contact in order to see if there is a fit.

Many thanks,

Dr. Kalanovic, Owner

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.
