Report: 3D Printing Will (Eventually) Transform Manufacturing
Although consumer applications have gotten a lot of attention, these will remain a small portion of the 3D printed parts market. By 2025, prototypes and production parts for automotive, medical, and aerospace segments combined will represent 84 percent of the entire market. (Source: Lux Research)
I think right now one impediment to "additative manufacturing" is the limited number of materials available for the process. That number increases at an ever-growing rate due to the probablility of success for the technology. I work with a machine shop that has made the investment in 3D printing to provide answers relative to "form, fit and function". Solid modeling can only go so far and most engineers like to kick the tires. Another great benefit is being able to provide marketing and sales a prototype to show customers. I have attended several focus groups in which models were presented to get consumers' opinions relative to design and limited function. These models were definitely preferable to on-screen presentations and demonstrated the part could be manufactured. Also, a model is great when you are designing tooling and fixtures for in-plant use. Excellent post Ann.
bobjengr, I think you're right about the materials angle, which is why Lux addressed that issue. OTOH, there are a lot more 3D/AM techniques for metal than has been apparent, which we're continued to report on. For instance, Monday's article on the Pratt & Whitney lab at the U of Connecticut: http://www.designnews.com/author.asp?section_id=1392&doc_id=262205
Uidea Rapid Prototype, "traditional manufacturing" usually refers to methods such as injection molding for making high volumes. I'm not sure how a rapid prototype company such as yourselves would be threatened by the topics discussed here. Can you clarify your question?
Hi, I think the subtractive manufacturing itself and the techniques which use subtractive manufacturing processes are traditional manufacturing, like injection molding, die casting, CNC milling, CNC turning, sheet metal fabrication, extrusion, etc, while additive manufacturing should be the future manufacturing such as the 3D printing we are talking here, SLS, FDM, SLA and so on.
The popular rapid prototyping techniques we have been using in China include CNC machining, vacuum casting/silicone casting, sheet metal prototyping, rapid tooling, reaction injection molding, extrusion prototyping and so on, all of them are subtractive manufacturing or need use subtractive manufacturing processes. Also, more and more prototype parts are being or will be made by 3D printing. So 3D printing would be big threaten to traditional rapid prototyping company like us.
Uidea Rapid Prototype, thanks for the clarification. I can see how 3D printing techniques might look like a threat. Some companies that do rapid prototyping and small volume manufacturing are using several different methodologies including 3D printing, depending on which works best in a given component.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
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.
