3D Printing, Robotics and the Future of Manufacturing

3D Printing, Robotics and the Future of Manufacturing | Alternativas: impresión 3D, hardware libre drones y otras tecnologías. | Scoop.it
The potential of 3D printing and robotics is nothing if not inspiring, but it's difficult even to imagine the extent of the inroads they will make in our manufacturing base or the myriad products they'll eventually produce.

Susanne Kahle's curator insight, August 6, 2013 2:21 AM

Interesting headline but IMHO disputable article regarding the main topic (connection between 3D printing/manufacturing, robotics and its impact on todays manufacturing industry):

 

It´s true that 3D printing/3D manufacturing is going to reach more and more product segments (depending on developments in different areas: material, resolution, size, hardware costs etc.) meaning the product portfolio based on 3D manufacturing . It´s also true that changes in production will be severe.

 

I guess it´s justifiable to estimate that two different types of businesses will be most involved during the first wave: emergence of micro businesses ("new business") and small and medium-sized enterprises (e.g. by shifting their production to 3D manufacturing, facing new and maybe unexpected competition by copy cats/innovators/low(er) cost production [lower market barriers etc.], extinction/emergence due to higher developed new products).

 

The article states ("What´s a Manufacturer to Do?") that manufactures need to stay on the leading edge of technology and ensure competitive pricing, high quality and rapid delivery service. Furthermore it references on two main protective barriers against new players using 3D manufacturing technologies: patents and economies of scale. 

 

To ensure competitive pricing seems a given, high quality is only partially interesting and always competes with lots of other aspects such as target groups, brand etc.. Especially regarding the named barriers several objections may be of relevance:

 

A. Patents: the world of physical goods is not dominated by other key laws of intellectual property as the world of digital media (creative work = copyright) - or to be more specific there are tons of physical goods not protected at all.

 

Unlike copyright patents are not automatically granted with the creation of a work, you have to apply for a patent, it expires a lot sooner and you have to sue to gain recompensation for an supposed infringement. Even more important a manufacturer/patent holder has to prove that the infringement actually led to monetary damage.

 

B.  Economies of scale: "Economies of scale can also help a manufacturer and offer some insulation against the competition. In such cases, the product becomes cheaper as production increases, making it difficult for a competitor to survive operating on a smaller scale." 

 

IMO especially *that* (so-called) barrier seems to work against and not for lots of "traditional manufacturers" (influence and range growing over time). As seen in many other industries it´s not very likely that traditional manufacturers will be able to adapt fast or at all - it takes a lot more effort (and therefor time) to change a business model/supply chain than to start a new by building up on existing fragments of an emerging market (e.g. hardware, software, scanning technologies etc.). Races between old and new econcomy (and the incoming changes regarding means of production are attracting tons of people that grew up with the mind set of that new economy) seem to favor agility and methods of the later when it comes to survival rates.

 

Furthermore 3D manufacturing in combination with robotics (not solely related to assembly lines but to ideas of self replication and merging of several production steps into one [e.g. combination of 3D printing with milling etc.]) will reach those product segments first that are especially eligible for these new technologies - for those old economy players the economies of scale barrier probably will fall very fast.

The best of two worlds: Solar hydrogen production breakthrough

The best of two worlds: Solar hydrogen production breakthrough | Alternativas: impresión 3D, hardware libre drones y otras tecnologías. | Scoop.it

Using a simple solar cell and a photo anode made of a metal oxide, HZB and TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose.

The photo anode, which is made from the metal oxide bismuth vanadate (BiVO4) to which a small amount of tungsten atoms was added, was sprayed onto a piece of conducting glass and coated with an inexpensive cobalt phosphate catalyst. "Basically, we combined the best of both worlds," explains Prof. Dr. Roel van de Krol, head of the HZB Institute for Solar Fuels: "We start with a chemically stable, low cost metal oxide, add a really good but simple silicon-based thin film solar cell, and – voilà – we've just created a cost-effective, highly stable, and highly efficient solar fuel device."

Thus the experts were able to develop a rather elegant and simple system for using sunlight to split water into hydrogen and oxygen. This process, called artificial photosynthesis, allows solar energy to be stored in the form of hydrogen. The hydrogen can then be used as a fuel either directly or in the form of methane, or it can generate electricity in a fuel cell. One rough estimate shows the potential inherent in this technology: At a solar performance in Germany of roughly 600 Watts per square meter, 100 square meters of this type of system is theoretically capable of storing 3 kilowatt hours of energy in the form of hydrogen in just one single hour of sunshine. This energy could then be available at night or on cloudy days.

We recently heard about a Solidoodler in Auckland, New Zealand, named Ivan Sentch, who’s building an entire car from scratch with the help of his Solidoodle, 2nd Gen 3D printer. When we saw photos of his project in progress, it was a bit hard to believe that this was his first time using 3D printing or that anyone would undertake something so massive with a desktop 3D printer. Leave it to one of our users to baffle our minds. We’re not sure if it’s insane, brilliant or both, but it’s certainly impressive.
