    Will There be Mali Driver Source or a way to build for Linux without being tied to only one kernel version? Source is highly unlikely, but it would be nice to have some way to build mali drivers for Linux for other than the one kernel version they pick of if you require an RT kernel for you application. I'd even settle for a tool that modifies their binary so that you can at least build for the kernel version you need vs the only one they chose to release a binary for.

  10. Re: The real reason on Australian Company Creates Even Faster 3D Printer · · Score: 1

    Combining different deposition technologies to manufacture items with multiple materials has been possible for quite some time. The problem is mostly with the patent system in the west. It's a patent minefield of obvious claims by patent holders that aren't even using the tech or are not interested in anything other than prototyping at slow print rates with very high profit margins on the materials. I expect an explosion of the tech in China or after a few more of the patents expire in the west.

    The main cost in developing a laptop is the high cost of tooling for the injection molding. http://openlunchbox.com/ plans on rapidly printing laptop cases to get around this problem and making all the main components as modules. SLA resolution is in the sub-100 micron range vs well over 100 micron for FDM. It's also an order or two of magnitude faster.

    They don't teach thermal management to EE's or ME's. The two groups each work on their own portions of the laptop and then cram a heat pipe and fan assembly into the case that the heat pipe supplier says might work. Thermally conductive thermoplastics have been around for decades yet they never seem to make it into laptop enclosures. Some are more thermally conductive than aluminum and are are not too costly for them to be incorporated into the design.

    There is a new open laptop project at Open Lunchbox starting up that intends to provide open reference designs for enclosures that use the enclosure as part of the cooling system.

  16. 3D Printing is Not Just Glorified Glue Guns on UK Ballistics Scientists: 3D-Printed Guns Are 'of No Use To Anyone' · · Score: 4, Informative

    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.

    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.

  20. This Won't Work Well With FDM/FFF on 'Download This Gun' — 3-D Printed Gun Reliable Up To 600 Rounds · · Score: 3, Interesting

    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.

  21. They Just Need Faster 3D Printers on 3-D Printed Car Nears Production · · Score: 1

    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.

  22. Re:Patents Are The Problem on Old Inkjet Becomes New Bio-Materials Printer · · Score: 1

    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.

  23. Patents Are The Problem on Old Inkjet Becomes New Bio-Materials Printer · · Score: 4, Insightful

    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.
