World's First Multi-Color, Multi-Polymer 3D Printer Unveiled

Posted by samzenpus on Monday January 27, 2014 @08:08AM from the look-at-all-the-colors dept.

Lucas123 writes "Stratysis today announced it will be shipping this year a printer that can use hundreds of colors and polymers to create production-grade or prototype objects without the need for assembly. Previously, manufacturers could print multi-colored parts using many different materials and assemble them after completion. Stratasis' Objet500 Connex3 Color Multi-material 3D Printer features a triple-jet printer head that combines droplets of three base materials to produce parts with virtually unlimited combinations of rigid, flexible and transparent color materials in a single print run."

  I think you make a good point there. Of course there is the flip side in which it may be possible to keep big ticket items in service longer since replacement parts could be less of an issue. It could be a boon to people doing restoration or maintenance work on older equipment, but it may also eat into sales of new equipment.
  And then there is the impact on logistics. If more fabrication of parts can be done locally it will likely reduce the total volume of shipping, for at least some part of the supply chain. That could increase the cost of shipping, although fuel consumption might go down. Could there be an impact like email has had on the Post Office?
  Hard to say what the total impact will be, other than things will be different. And you are right in stating that it isn't always an easy transition.

  All of the printers I've seen are based on sintering powdered metal into a single larger piece of metal. My understanding of the process is that sintered parts are no-where near the strength of a solid piece of metal. Also, engineered metals used in performance components are selected for the specific capabilities of the alloy. Printing your tie-rod ends from a generic metal is likely t result in a sub-standard part that fails far more quickly than you would otherwise expect.
  This isn't to say that there isn't some other non-sintered 3d printing process out there I haven't heard of but I'm not aware of any such system being anywhere even near production.

  Not Likely however it may make it more efficient and able to produce parts for a longer time. It was explained once to me that when a manufacturer makes parts they estimate how many spares they will require for the future, manufacture them, then store them. The storage cost is incrementally added to each part hence why they are so expensive. 3D printing would go some way to eliminate the storage problem but it would not eliminate need for special materials used by the manufacturer or the precise specs which they could have in their own printing machine. Also when the last part is sold then your product is obsolete and no longer repairable with genuine parts. 3D printing could also make your product last longer in that parts would be available indefinitely.

  I've read up on this a bit, I'm by no means an expert but I have a broad overview of the situation. In short, it is this: Forged metal is by far the strongest thing you can get your hands on, but sintered metal is stronger than mere cast metal. This assumes that all else is equal, that is to say, that you're using the same alloy. However, many parts are made out of alloys selected for cost, and not for optimal function. Which leads us to our next point.
  
  Printing your tie-rod ends from a generic metal is likely t result in a sub-standard part that fails far more quickly than you would otherwise expect.
  What do you mean by "a generic metal"? Seems like most tie rod ends are made from forged SAE 1045 steel. If you used something even more serious, then you could get away with it being sintered.
  The big problem with sintered metal is the lack of large grain structure as compared to forged. It gets a very regular grain structure, which is desirable, but the grain is very small. What this means, besides being slightly less strong, is that the failure mode is worse. Forged steel tends to bend, while sintered steel tends to break. Or in more sciencey terms, forged steel has a greater elastic limit and a more desirable failure mode. But if you make it strong enough not to break in the first place, that's not a problem. The problem comes when you try to use the same alloy with sintering processes that you used to forge. You're just not going to get the same results, as proven by the late (2000+) 7.3 powerstrokes.

This is a RepRap Mendel Printer designed to work with three colours or three different plastics at the same time.

In addition to the opportunities this gives you to put lettering on 3D prints and to produce muti-coloured objects, we are researching many functional materials for future release that you will be able to build with.
Well, I looked at the website and the information they give on the site about the tri-color is very vague! It seems that they intend to do so, and that gives me an impression that they did not have the capability of mixing color at the time they were advertising. They just want to advertise their product to get their name out first.
My understanding to answer your question about injecting the dyes on the fly, is that it is very difficult to perfectly add a color to the clear filament. In other words, it is not easy to evenly coat the filament and it would require multiple injections to get the right color. Then they may need to mix the colors to the right saturation/hue first before applying the color to the filament. This is not a 2D that can easily do it on one run. Not saying it is impossible, but they may not find the right and economical way to do it yet.

Color gamut coverage is harder with pigments than glowing emitters - at least if the paint matching pigment carousel at the hardware store is anything to go by.

Probably not.

You probably are.

As someone who works with industrial pigments. Yes they are. Clear bases are not to bad, but every white base is slightly different.
You add multiple base materials and each one will take pigment differently. So rubber will tint differently, than each type of plastic, and each hybrid will vary slightly too. It will make matching actual colors consistently a pain in the ass. Possible with good chemistry. But a pain.

This is actually just a modification of the existing Objet printer. We have one at work and it mixes 2 resins. This gives it a great capability. You can load a soft rubber like resin and a hard resin. Then you can program it to create any hardness in between and it will do it by mixing them. So what this new machine does is just add another (or more) resins to the mix so you can control color as well.

3D Printed Helmet @ Home-- No Good by eepok · 2014-01-28 09:03 · Score: 1

Nice bike helmet, but I won't be wearing a 3D printed helmet unless it passes all the same tests that all bike helmets in America pass.
