Re: 3D Printing

While I'm itching to acquire a 3D printer for my hobbies, It will be a while.

And I am just looking in from the outside, so to speak.

I understand that objects with overhangs are still difficult to produce. Perhaps they can be created with snap off supports or such but you lose the smoothness of the finish in that spot.

Am I correct in my understanding?

Still, Printing my own custom nosecones for my amatuer rockets would be a massive game changer.

pre-processing for 3D Printing

Charles, thanks for the post.

Can you elaborate more about what pre-processing is necessary?  You had mentioned changes in CAD modelling...

At the event, Mydesign, the Stratasys executives made a point of letting journalists know that the popular conception of 3D printing is inconsistent with the realities of using it in manufacturing settings. As you point out, there are a lot of applications that don't lend themselves to 3D printing.

I agree, naperlou. I think we're only scratching the surface here. Companies will learn how to combine information technology and 3D printing in all kinds of industries to produce customized products that no one has thought about yet.

"Injection molding has improved to the point that it is possible to make small production runs with molds that are cheaper.  They may not be as long lasting as the traditional mold, but they are just fine for those smaller runs on an inexpensive machine."

Naperlou, you mean that 3D printing objects are of high quality and have better durability? I think in both cases the composition of material may be same and only the finishing may be better in 3D printing.

Charles, it's very nice to read this interesting article. I read many articles with respect to 3D printing and in one of them somebody specified that it can print ornaments, medicines etc. I think it peoples are aware only about merits and they presumes that it will be able to print everything.

Chuck, 3D printing is another good tool for manufacturing parts.  In the past, CNC machining allowed cost effective production of small runs of parts.  This is still true.  Injection molding has improved to the point that it is possible to make small production runs with molds that are cheaper.  They may not be as long lasting as the traditional mold, but they are just fine for those smaller runs on an inexpensive machine.  Often the molds are made on a CNC machine.  3D is another low production rate technique that can be used in various situations.  In "low" volume industries like aviation, this technique is very useful.  In a mass customization environment 3D can really shine.  I wonder when we will see personalization of prodcuts like automobiles with the addition of 3D printed interior parts (like special cup holders).  Information technology coupled with 3D printing could make that a reality.

Design, simulation, manufacturability, and prototyping: All of these phases are being pushed forward and progressively by underlying technologies.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
