  • This is not my first rodeo. I have used printing to transparency paper printed to by laser printer before for making resist masks. Also, ferric chloride is stored in a plastic container. Most of my previous etching was done in plastic containers. The amount of time spent in the solution will certainly not affect the plastic any.

  • There is no chlorine in any 3D printer plastics that I know of. I have been printing for a while now and everything is pure. I mostly use ABS. Using chlorinated plastics would be highly dangerous to print with.

    PVC is not an appropriate plastic to use for 3D printing. I don't know where you got your information, but I make as well as buy filament. I have pellets of various plastics and NONE of them contain chlorine.

  • Why not just use an SSR instead of a relay? SSRs are really cheap anymore.

  • I am interested in doing this with a 3D printer to lay down the mask. I think it should be done minimally like you would with a metal router. So the mask would be different, but in concept it would be the same for etching. I don't think the plastic will be all that difficult to remove either. Probably don't want to use a water soluble plastic though. The etching solution would eat that.

  • Old post, but consider finding some investors to go to the next level. There are people actively looking for investments that can go to the next level. Also, consider licensing the technology to someone. You have IP in your code. It would be better if you had a patent or patent pending.

    I am part of a company that found an investor to the tune of a couple of million dollars for an industrial application. There are huge ranges of people actively seeking out products to invest in.

    Also, go talk to the FCC. They might have programs available for small businesses. Many times government agencies get grants/bonuses for fostering small business ventures. They might have connections for finding funding as well. I know many local areas have business development groups that meet to connect people looking to invest with people who build things. Also, get comfortable with NDAs to protect yourself against people who want to "look" at what you have.

    For the business that I am in we had to pay upwards of $100K to get our product NFPA certified. This took 2 to 3 years. Now you might not consider your device to be dangerous. However and agency has no such luxury of assuming that. I am sure there are hundreds of devices that could kill someone in the wrong situation. So this is not about YOUR device at all. Its about keeping the airwaves clean so things operate smoothly. I mean, you would feel bad if it somehow caused someones pace maker to fail right?

  • Nick, glad to see you are sporting a beard. New product Friday should always have a bearded one.

    Great product coverage. Thanks

  • Rob, you can go, but the beard stays. Good luck.

  • And yes, it is a horrible hack job...

  • Late to the party I know, but I find it disturbing nobody found this connection: Inconceivable

  • Where did you read something about someone calling in? According to the article another girl claimed that Eyman made threats. There was no call. All we have to go on is what people involved had to say.

No public wish lists :(
