They take your money, run a cheesy keyword patient search, file your description as the application and then run like Frenchmen. Patent lawyers are a tar baby.Īll ‘inventor support’ companies that advertise are pure scams. If you don’t have millions to enforce your patient, save your initial $US10k per (per patient, not per idea, 10k is a rule of thumb and is likely low now). The remaining 0.001% might have heirs that collect (e.g. The other 0.999% winners have deep pockets. Patient lawyers are the only winners in 99% of patent disputes. That whole process requires many expensive shyster hours. Hopefully one patient will be in the middle ground. So you do all of the above, so your ambulance chaser has something to work with. The ones that are too vague, somebody finds prior art, patent not valid. The ones that are too specific, somebody just changes a detail, patent not applicable. Multiple patients with varying specificity. To cover an idea you take a shotgun approach.
With no knowledge of if there is any money to recover. That means they now get to spend even more money trying to enforce it. That difference probably wouldn’t stop the patent holder from suing anyway since they no doubt want control of the very *idea* of printing with PEEK… but still.Ĥndreas former employer has a patent. The manner by which they accomplish it just looks different. Surely I’m misinterpreting this patent, but it looks like the only similarity between US10946578B2 and ND3Ds version is the understanding that a PEEK workpiece needs to be kept uniformly near its glass transition point by way of some form of secondary radiant heater above it.
This radiant heater does appear to be designed to be attached around the print head itself… and is described as being independently regulated… but it appears the patent’s “radiant heater” is an array of small directional heaters intended to heat only where the part actually sits, much like a multi-zone heated bed… but that concept seems to contradict the idea that the radiant heater is coupled to the moving print head so I’m not certain that would even work. Posted in 3d Printer hacks Tagged 3d printing, exotic filament, high temperature print, peek Post navigationĭoing my best to parse patent-ese, I can see the patent in question does describe using some form of secondary radiant heater as a “surface heater” for the purpose of keeping the “workpiece” warmer to allow for a better surface quality/adhesion. Not to mention, there is no shortage of high-end commercial offerings. We’ve seen other high-temperature printers, of course. It isn’t clear to us that it isn’t just control of AC power and a heater, but there isn’t much information about what you have to do differently to work in PEEK or other exotic materials. It appears you can buy the boards, but we’d like more information on what makes them different. We were looking for more build details, and we hope they are forthcoming. Looks like it would keep your shop pretty toasty on a cold morning. The halogen heater wraps around a conventional hot end. You do need precise control of the halogen light. Contrary to common wisdom, suggests using an open frame for the printer. Compare this to PLA, which melts between 150 ☌ and 180 ☌ and has a glass transition temperature of only 60 ☌. PEEK has a glass transition temperature of about 143 ☌ and melts at 343 ☌. Logically, if PEEK is used near the hot end of regular printers, it must need a higher temperature to print. Using a special controller and a halogen lamp, you can modify your own printer to use this exotic material often found in printer hot ends. You can get the details over on Hackaday.io, and there are a few YouTube videos below.
has a different idea: printing with PEEK. Normally, when you think of PEEK in 3D printing, you think of a part made of PEEK, suitable for lower-temperature plastics.
