Hey all
I have complained about disrespect. It is too common. I really dislike how stratasys is behaving. The disrespect I receive often makes me not share anything.
I am patent-pending on a new way to 3d print metal. It is a futuristic take on lost wax casting. I print the metal and the support material simultaneously, on a plate that is lowered into a crucible. An induction coil fuses the metal. This takes a minimum of 10 minutes versus the multiple hours required in all existing methods.
And??? Either elaborate or clarify why you needed to make this post .
I donât see how this relates to Stratasys.
You say you 3D print the model and supports to then fuse the model using induction heating.
Unless you want to overboard this limit things things to ferrous alloy compositions.
As supports are required I can only assume you came up with sort of a soldering paste to make it happen.
Bind the metal enough during printing to be stable, get it close to melting temp in order for the binders to go away and the flux to allow for a more evenly bond and surface.
Considering the crucible and temperature requirements to âextrudeâ steel I simply guess it is made out of silicon carbide or similar material to act as radiant heater rather than the model itself being heated by the induction process.
In this case your idea would not new at all as this was done before and more than once.
It never took off due to the costs and fumes produces during the printing and curing process.
You say it takes about 10 minutes vs the multiple hours for conventional methods.
Can you elaborate on that please ?
A powder printer does not really require any curing of the models, the metal is properly fused with a laser.
I just assume that not even you can print a complex model with supports in about 10 or 15 minutes.
So how long would it take you print a model is layer heights or resolutions common for powder printing and how long for the induction fusing process after ?
It is easy to make bold statements if there is no base to compare them to - just sayingâŚ
With a pending patent there wonât be any meaningful details revealed.
But what about a pic of the model after printing and another for after the fusing ?
They would not reveal too many secrets or would they ?
Your guesses are way off. Powder laser sintering is slow and the surface is not great.
My approach streamlined all the inefficiencies of lost wax casting or powder fused by laser into a way that is much faster. The layers each have support material and metal. After fusing the entire thing by induction, the support material pours off like loose powder leaving an unblemished surface. This picture is after manual polishing.
Direct Metal Laser Sintering (DMLS) and Electron Beam Melting (EBM) produce fairly precise parts by fusing powered metal together by âpaintingâ the areas they want fused with a high power âbeamâ of light or electrons. But it takes a lot of energy to accomplish this. The powder has to be pre-heated to a very high temperature so the laser or electron beam has less work to do. And the laser/electron beam still have to be fairly high energy themselves. Lots of precision mechanical parts and electronics that have to operate reliably at high temperatures. So the machines are expensive to buy and expensive to operate. Which is why there are methods like extruding a metal-particulate infused FDM filament or binder jetting a metal powder, and then post-print sintering it to turn it in to a solid part. These methods are less expensive enough people are willing to deal with the downside. Sintering causes the print to shrink and there is variability so itâs hard to get âpreciseâ parts without post processing. Parts arenât the strongest, either, because the sintering is imperfect, there are often small voids that remain. Parts can have issues with porosity.
A quick query to ChatGPT shows there are already 3D metal binder jet printers that use wax as the binding agent.
Another query shows there are 3D metal printers that use induction heating to sinter the green print.
âPatent Pendingâ simply means a patent has been submitted. Itâs in no way a guarantee that the patent will be granted. Many more patents get rejected than approved.
A patent has to be âoriginal/novelâ and ânon-obviousâ to someone knowledgeable on the subject matter, but this doesnât seem like itâs either. A mechanism to automatically move a green print to the induction sintering oven probably doesnât make it patentable since thatâs an âobviousâ invention. And youâre going to have to provide more details to make a convincing argument that the printing method meets the criteria, Iâm afraid. Wax as a binding agent isnât it.
And Iâm not understanding what Stratasys has to do with anything, or why people disrespect you. Or why you made that your preamble. Complete non-sequitur. Confusing. 
No offense bro, but canât stop wondering whatâs the point of launching this topic here. Thereâs little chance, if any, that your print tech would be of interest or of any practical use for most of us. It seems to me that it would be more wise to target those industries that do have an interest in such technology. Out here, we are more into home 3d printing (hobbyists), freelancers, and small to medium sized businesses, and unless your tech proves to be reliable enough and able to provide quality results each and every time, and your licensing fees are really affordable, personally I doubt anyone here would go for it. There might be people here that could see some business benefits in providing printed products based on your technology, but it remains to be seen how much one has to invest in the necessary hardware, software and materials, to be able to print, and, obviously, how costly and reliable your technology is.
Itâs important to start conversations on the right foot, especially when youâre passionate about something. Instead of feeling disrespected, try starting with a friendly toneâyou might find that people here are just as excited to talk about the technology as you are.
No. That is never the case. Just looking at these guessers, already assĂšming my invention is not novel.
Stratasys is attacking bambu and i was thinking to talk to bambu. But no offense, you show as always, not worth it.
It sounds like youâre really passionate about your invention, and thatâs great. Everyone here brings different perspectives, and sometimes the initial reactions may seem critical, but itâs usually because people are trying to understand your idea better. Sharing more details can help clear up any assumptions and lead to more productive discussions.
I was interested, but not anymore. I am not interested in learning about something from someone who is Immediately defensive.
Youâre doing yourself a disservice. I suggest maybe hiring a PR person.
Peace.
About that metal printing stuff. Here a technical process of 3d metal printing on Markforged printers. Just print, wash, dry and bake in the oven. Done.
Markforged wishes they can do what I do. I am defensive because everyone treats new inventions and inventors VERY POORLY.
My method is 9 times more profitable than lost wax casting. 20 times faster.
This is the closes to my method but they grind metal making for potentially self igniting and dangerous to inhale powders. The use ceramic and bake for 10 hours before breaking off the ceramic support.
None of you expressed any welcome or interest. Honestly when i began I knew nothing of the time humans waste on their supposedly brilliant or revered ancient â â â â .
And my machine costs around $6k, not hundreds of thousands.
in other words:
'buy from me, Iâm cheaper than the competition ',
âbuy from me, my process is way profitable, safer, faster and better than the competitionâ,
and finally (but not lastly),
âbuy from me, or else Iâll feel that Iâm treated poorly, you ungrateful ignorantsâ âŚ
No offense bro, but being that defensive doesnât help make your case
You should be prepared to accept that people tend to dispute and argue until proven otherwise.
You should be prepared to debate, argue and demonstrate (beyond any reasonable doubt) that your work deserves to be recognized and accepted, and eventually adopted.
Being defensive will only alienate those you target as your main audience as these tend to ask (quite) some uncomfortable questions, dispute some of your claims and might even try to demonstrate youâre wrong.
It ainât bad will and none of them is looking to make you feel or look poorly. They are simply trying to ascertain, in the most objective way available to them, whether what you came up with is worth their time and (eventually) hard earned money.
Alternatively, you could consider gathering visibility and financial support by launching a kickstarter campaign.
Thatâs because you showed nothing tangible that can be compared to what exists.
Iâm sure a lot of people here are very curious in general like I am, but as a result âI have this cool thingâ falls flat instantly if there is nothing to satisfy the curiosity, quite the opposite it frustrates people and thatâs what makes them dismissive because they know themselves that anyone can brag about anything when they donât show any of it, it doesnât even need to exist - and know that happens all too frequently, most of the time when someone comes with bold claims about something but doesnât want to show the details itâs because itâs not actually achieving them.
Show the whole process of making a part and then people will have something to give relevant comments about.
If itâs too early to show anything then⌠itâs too early to talk about it too.
Then please provide a demonstration.
this bit (of humor) says it all. 
This bit of humor is rude and offensive. I expect interest from a community i am part of by virtue of having bought an x1c, but as usual humans are morons.
Bambu labs might have had an opportunity to share my tech despite stratasys. Now, not a chance will i help them or you.
I am patent pending. I cannot reveal too much. All inventors are expected to be financial and business experts and have to deal with trolls. You people only prove it.
I am happy to see your guesses are so inside the box as to be laughable.
Binder jetting? Nope.
Electron beam or laser? Ha.
Complex shapes and detail easy as shown.
I do not demand anything but better behavior than typical human arrogance and ignorance.
As i would have given and have done if any of you posted about a topic such as trying to incorporate cleaning filament to reduce or eliminate pooping.
I am done with public discussion.
