Enclosures and Cases / Printing vs Molding
« on: January 31, 2015, 10:43:08 AM »
The cost of tooling for a typical laptop enclosure is over $250K

The enclosures may be printed using rapid SLA with engineering photopolymers. They can be entirely made from photopolymers or partially photopolymer with an aluminum alloy chassis similar to the T60 thinkpads.

Another option is to use aluminum alloy and machine the entire enclosure or again a combination of aluminum alloy shell along with photopolymer components.

Short to medium production runs of various case and display sizes is easy as well as custom one offs since we aren't making tools.

Cases / Why SLA Printed vs Injection Molding
« on: January 31, 2015, 10:37:22 AM »
The costs for tooling are >$100K for injection molding. To keep initial costs down until there's enough demand or interest we'll be printing the enclosures vs injection molding. Printing also allows you to make custom cases quite easily that would require new tools for injection molding.

Cases / SLA Printed Cases

3D printed enclosure using engineering resins (not FDM). Everyone seems to be stuck at this step, even Google.  Not sure why since the tech is decades old.

Youtube doesn't always like starting so far into a long video. The conversation about 3d printing starts 56 minutes and 10 seconds in.
