Comment: 3D Printing is Not Just Glorified Glue Guns (Score 4, Informative) 490

It's sad that 3D printing had become synonymous with FDM or glorified glue guns (GGG). There are lots of different technologies that fall under the umbrella of 3D printing.

Here's a gun that was 3D printed using DMLS (Direct Metal Laser Sintering) for the metal parts and SLS for the grips. It's both durable and viable.

... so that you can buy or try any app just like you would download apps for linux distros, without having to register or give an app access to all my stored info? Why does a calculator app need to access my contact list or location data? Will the results vary based on my contacts or location?

And while you're at it an open source version of Android. I'm happy to pay for apps that I really want but lets at least have a layer of security between applications and stored data, location, call history etc etc

They probably don't have access to an SLS printer which will work for an application like this along with the right alloy.

SLA may be used to print the part in one step or print a mold that may be used for lost wax type casting of several alloys durable enough for an application like this.

The resolution and materials commonly available for FDM/FFF are too poor for application like these. The quality of the print is just too poor and they are only using p400 ABS for material. That is why their prints aren't very durable.

SLA however offers the resolution and the materials to produce parts that are strong and reliable enough for these types of rugged applications. Some photopolymers for SLA are 100-1,000 x stronger than the ABS they are using.

FDM is slow compared to new SLA, micro-nozzle and inkjet deposition processes. I'm not sure what FDM printer tech from the 80's they are currently using, but by using newer additive manufacturing techniques and new materials they can cut their 2500 hour print time down to well under 250. Inkjet and SLA is capable of print rates in the Liters per Hour and easily down to the 10's of microns of resolution. You just won't find these types of printers sold by the old 3D printer co's sitting on their old 80's tech that they are still trying to squeeze every last day out of their old patents.

Some of the problems are with patenting the obvious or having overlapping patents. Too many patents overlap each other or are painfully obvious that are granted with the idea that these issues should be settled later in the courts. This has led to abuse of the original intent of the system.

If society also decides that patents are only for the purpose of financial gain and the deliberate hinderance to scientific progress and the betterment of mankind then they deserve what they get. Most people are just unaware of the current gaming of the system and don't feel this way.

Inkjets have been used for years to print living cells and also the scaffolding for cells to adhere to. The problem isn't so much the tech but the sea of patents blocking anyone from bringing a complete system to market. When this problem is solved look for rapid progress on many fronts. Until then maybe it will only be available in countries that favor technological progress over nurturing an obsessive compulsion to hoard money that goes unused.

Patents are the problem with tissue engineering, just as it is with other 3D print applications. I'm not against patents. It's just that the current way it's being run isn't working to help move tech progress forward, it only helps a few to make money and also keep control over the rate of progress.

Security seems to be much higher here currently. We are having a more difficult time right now shipping anything such as liquids and chemicals using the local logistics companies within China. I've asked around, and the most common answer is that it's due to it being right before the busiest travel period in China.

Google Map App's Version of Anonymity Might Violate EU Privacy Laws 89

Posted by timothy
from the of-course-we-don't-know-your-name-#449709761 dept.
Ars Technica reports that Google's map application for iOS, however popular it might be with users, raises red flags with European regulators, who maintain that it by default does not sufficiently safeguard user privacy as required by EU privacy rules. Ars quotes Marit Hansen of Germany's Independent Centre for Privacy Protection on why: "Hansen's main gripe is that Google's use of 'anonymous' is misleading. 'All available information points to having linkable identifiers per user," she told Computerworld. Hansen added this would allow Google to track several location entries, thus leading to her assumption that Google's 'anonymous location data' would be considered 'personal data' under the European law."

Maybe you haven't seen the SLA printer projects that use lasers or DLP such as LemonCurry for curing photopolymers? Feature sizes are often down to 1 micron per layer and only a few microns for X and Y.

Photopolymers are available in a wide range of properties that are tough enough for use as end products and not just product concept look-a-likes. Photopolymers for inkjet have also come a long way and are also used to create rigid and durable end products with features down to 25-50 microns. What you might be used to seeing are the FDM or FFF (fused filament fabrication) RepRap type printers that print with molten plastics with much lower resolution in the order of 0.3mm.
