Another Aussie! Ariel and his team are from Brisbane, which is in Queensland, Australia.Dave interviewed Ariel on site at CeBITMoved to Brooklyn where there are other 3D printing companies:Sols - 3D printed soles for shoesShapeways is also there.The product that Cartesian Co makes is called the Argentum. Formerly called the EX1, when it was raising money on Kickstarter.They are currently on batch 4. 200 total have shipped, 80 went to Kickstarter backers.The Argentum uses 2 part ink vs 1 part ink (nano particles) make by companies like Dupont, Mitsubishi and Mithode. Currently these only are advertised to print on pre treated materials.The printer itself uses old inkject cartridges to deliver the inks.Competitors:VolteraVoxel8AgICReal competitor is low cost batch services and milling/etching boardsThe focus was on an MVP...just like in Southpark.The reason for using silver is copper chemicals are much more dangerous to handle.Cartesian is planning on creating multi layer boards using insulative ink in selective areas.One interesting future avenue is printing on fabric/paper. The paper can even be reflowed. A current issue is stringing, which causes unwanted shapes on a print. The specs - 20 mil space/trace.Dave was interested about the business setup moving to the US. Cartesian is setup as a corporation in Delaware, as many are.Apparently internet denizens can now also apply to be part of Estonia as a digital citizen. We were of course discussing "Fartesian Faux, Inc" in all of these discussions.Though investment in startups is changing via the JOBS act, it might not be as much as people expect. Public/general solicitation is still very restricted, especially since the SEC rewrote some of the rules. The main idea is to protect investors without much money from losing their life savings. This was implemented during the great depression. China is experiencing a crash right now because of similar boundless enthusiasm in their stock market (and the resulting correction/crash)Many thanks to Ariel for telling us more about circuit printers. It seems like the desktop technology has some fun years ahead. Chris is looking forward to getting his skin printed on and eventually getting a Cartesian chip printer.
