Is 3D printing good or bad for construction jobs?

Now You can now 3D-print a house in under a day  

I love this discussion thread about the recent article by Mike Murphy at QUARTZ on 3D printed houses/structures and the impact of these emerging and potentially disruptive technologies.  There is a lot of concern for the future of the construction industry and jobs, which is understandable.

I live in California, where it costs more in materials and construction to frame a house vs. whole finished properties 5x in size in some other states. That means most of the budget goes into permitting, special materials and expensive and inefficient construction techniques - things that eat money otherwise spent on quality finish and detail by skilled professionals.

In a market like ours, what I believe this technology will allow for, assuming it nets out more cost-efficient, is more spending on finish work, professional carpentry and finish skills, vs. costs dictated by construction standards and code requirements. It will also demand a whole new class of labor skills to operate the equipment.

I predict the savings will be to the benefit of the home owner - and the quality of the result both structurally, and aesthetically - and not necessarily at the expense of skilled labor. Traditionally speaking, new technologies in construction techniques have fed the job market, not squashed it.

What do you think?

 

Move over Moore . . . there's a new law in town!

According to this article by Clive Thompson of WIRED Magazine, there is a new law in town:  Lass' Law.  Moore's law has accurately predicted the increase in computing capacity of chips for the past five decades.  Now, Lass' Law predicts to do the same for Fab Labs.  

Clive states: "If Lass’ law continues, custom fabrication will explode. In roughly a decade we will have a million fab labs. In 30 years it will be a trillion; they will be as omnipresent as the electronic devices currently scattered around your home."

Yikes!  That means a lot of intellectual property floating around to track for attribution.  makeSEA is designed specifically so that independent designers can share, sell, and track their intellectual property among a trusted community –including fab labs in meatspace. makeSEA protected projects can be managed privately, shared among private teams, or the exposed to the world - you choose.

3D Printing and the Olympics

Whether you strive for Olympic gold downhill skiing, or couch-surfing, it’s easy to understand why 3D printing makes a difference - remember, this technology is on it’s way to your living room. Read the full article here.

 

Innovate

At makeSEA we're all about innovation. Through the process of change, alteration, transformation and metamorphosis, using new methods and creativity, that new or improved products can evolve from an existing idea.

Stephen Coyle, a makeSEA member, is experimenting with Christoph Laimer’s 3D-printed Halbach Motor design (/makesea/1gt) to see if he can get it to generate more power. Stephen is casting the core of the motor using his 3D printed parts, a propane foundry,

and scrap metal.

Exploring magnetic PLA and other 3d printer filaments

 

3D printed motor stator with magnetic PLA

Question of the day: Can the reduced magnetism of 3D-printable magnetic PLA from Proto Pasta actually resolve efficiency issues by reducing eddy currents in a 3D printed motor? It’s an interesting question posed by Christoph Laimer during his extensive experiment using magnetic PLA to print the stator core for a 3D printed brushless motor. In fact, he even poses the question of whether the stator core can be printed with non-magentic PLA (since the magnetic PLA is truly much less "magnetic" than standard iron alloys and, yet, still functioned beautiful and efficently in his 3D printed brushless motor). 

Eddy currents are a byproduct of rotation of a magnetic field. In conventional motors, harder iron alloys produce more eddy currents than softer alloys. Therefore, Christoph’s theory that the reduced ferromagnetism of Proto Pasta’s magnetic PLA could have a positive effect on the motor’s efficiency is worth exploring in detail in another post. In the mean time, check out the details and results of his very successful attempt to 3D print a viable motor, and come back here to comment on your thoughts about eddy currents and magnetic PLA.

Christoph has written a series of five articles on testing and using magnetic PLA. Look for these articles on the makeSEA wiki:

Magnetic PLA is just one of many tpes of filament available to consumers in the 3d desktop space. In fact, since Christoph experimented with magnetic PLA there have been so many new types of filament available to the consumer market, it's hard to test them all. We recently tested a new conductive PLA, which we found more efficient but harder to work with. 

If you have used or tested any of the conductive filaments, please share your experience with us.

Why 3D printing will change the world: reason 13

Before and after experimentation with the motor.

If you are reading this, you probably don’t need to be persuaded that 3D printing is changing the world in many ways. Its effect on manufacturing, shipping, inventory, and really the world economy as a whole is greater than we can imagine; not to mention the social and humanitarian good it can do by making medical devices and basic life serving technology and goods available more quickly and at a much lower cost.

3D printing provides a much more efficient way to prototype and produce goods when compared to traditional manufacturing methods that can be slow to develop and tend to create a lot of waste product. In the chain of processes that deliver the final goods, there is 3D printing’s significant effect on prototyping.

3D printing technology (also known as additive manufacturing) was introduced in the 1980s, and until very recently, the technology has remained out of the hands of most individuals unless they had access to an industrial machine. That means, unless you were a lead engineer at a large manufacturer, you probably would never print a prototype of anything, let alone some idea or concept you were curious about. The availability of 3D print technology to consumers has changed that. Opportunities for invention, exploration and creativity that spring from 3D print technology are leading to out-of-the-box trials and prototypes that were previously cost-prohibitive. These same opportunities can, and in many cases are, being used in the classroom.

3D printing in education is vital for today’s students who will enter a job market that values different skills not fostered in previous generations. 3D Printing can be used to teach strategies that will develop future in-demand skills in science, technology, engineering, and math (STEM). Not only will 3D printing help develop these skills, it also promotes creative (including artistic) and analytical thinking.

3D printing is unleashing conceptual designs from the minds of students, amatuers, professional 3D designers and engineers worldwide. And that is a good thing. It allows for trial and error and ultimately success. As was the case when Christoph first set out to 3D print a brushless motor. V0 failed, a failure that couldn’t be predicted from the CAD modeling alone. Printing and testing the model was something that couldn’t have been easily accomplished at home in years past. With the help of his 3D printer, Christoph was able to print, test and ultimately create a fully workable brushless motor, and has since gone on to create so many other amazing pieces.

Airflow gaps for 3D printed motor with ABS material

Heat is an important consideration when working with 3D printable ABS and PTEG materials. Even though both filaments have solid strength and a melting temperature of around 250˚, it's important to keep heat gain in mind, particularly when you are using it as an enclosure for the rotating stator of a brushless motor.

For makeSEA's 3D printed brushless motor, Christoph chose to allow ample space between the stator and rotor for sufficient cooling air flow. Fortunately the necessary space wasn't so big that it compromised the size/usability of the motor. What are the other options for dealing with heat gain in a project like this?
