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

samzenpus posted about 3 months ago | from the look-at-all-the-colors dept.

Technology 85

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."

Well, two reasons. Firstly, basement-dwelling nerds have far more experience with their own equipment than anything else, so they're far more confident designing dicks in CAD than anything from the other side. Secondly, dicks are supposed to be hard when performing, while boobs are supposed to be soft, meaning current 3D printing technology is far more suited to making functional dicks.

I was under the impression that the tricolour-mendel can print in 3 colours, whereas this one uses 3 base-colours to create any of the millions of different combinations, very much like regular printers and RGB-displays and the likes.

Re:Absolute B$ (0)

Anonymous Coward | about 3 months ago | (#46084935)

funny but it was my understanding that a tri-color mendel used 3 colors mixed in the head to make many colors.

What I though of while reading this, in the event of a patent, was why not add liquid color chemicals into the print head in a sufficiently turbulant chamber so only a clear filament is required? They add the dyes to the material at some point so why not at the injection point.

Re:Absolute B$ (3, Informative)

parkinglot777 (2563877) | about 3 months ago | (#46085717)

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.

Re: Absolute B$ (1)

peragrin (659227) | about 3 months ago | (#46087113)

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.

Re:Absolute B$ (1)

trout007 (975317) | about 3 months ago | (#46089885)

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.

Don't get me wrong, I'm enamored with the idea of never having to buy an actual part again myself, but I just don't see it happening anytime soon, for a number of reasons, most of which involve direct government interference into your life.

Meanwhile in the responsible world high end 3D printers will make custom parts for cars/rockets/etc that can't readily be made any other way, and they'll be subjected to all the usual fitness tests before actually being used somewhere that puts human lives on the line.

I can tell you're not a lawyer. Probably not a busy-body, either.

Let me answer your question with a question: To date, not one person has been killed or harmed by a 3D printed gun; so why are busy-bodies and politicians already trying to regulate the 3D printing of guns?

I just recognize that, in a population this size, there will be people out there with nothing better to do than dream up worst case scenarios, and demand legislators take action. "For the Children," or "To Stop the Terrorists," or some other bullshit like that. I don't doubt they'll come up with a reason.

Kind of the same reason that people want to regulate the sale of guns more than the sale of metal in general. Guns only kill things; that is their stated purpose. But there are many positive and constructive uses of other tools. In particular, this 3d printer.

I see this more for car dealers,mechanics,distributors rather than home owners. You will still need raw materials. Home owners don't like keeping boxes of screws.

No you will take your car in and they will print parts you need. You want new gizmo they print it and ship it.

The first thing I see being mass produced will be gaskets ,washers, prints etc. Which are generally a massive waste in cost of materials, etc

Re:Nice (1)

GameMaster (148118) | about 3 months ago | (#46085285)

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.

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.

On the other hand, having ridden one down from factory to near-junkyard, I can tell you which parts get harder to find replacements for over the years.

The "go" parts tend to be pretty generic, and in modern cars with everything packed in tight and assembled by machine, the expensive component of the repair is generally the labor. The "pretty" parts, on the other hand, are changed often on a yearly basis and even something as basic as rubber window trim gets hard to find after a decade when the original has rotted out. Much less stuff like taillight lenses. So if you could print up a an exact replacement without having to scour junkyards, it would be great.

cold fjord (826450) | about 3 months ago | (#46084719)

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.

Re:Nice (0)

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.

MobyDisk (75490) | about 3 months ago | (#46084909)

I would love to see the insides of this thing. The biggest problem I see is that the mixing process requires you to push all the plastic out of the extruder and prime it again with the new filaments. That would waste a lot of plastic at each color change. So if you printed something with multiple colors per layer, it would waste a lot lot of plastic.

Does anyone have any more details?

Re:So how do they do this? (2)

MozeeToby (1163751) | about 3 months ago | (#46085095)

You know all the variables though, you can figure out when to change the color so that when it gets through the extruder to the head is exactly when you wanted to change colors anyway. You might have to eject a bit if you don't want any mixing, but the waste could be quite close to zero if they did things right. On the other hand, the pictures and videos they show do not make it look cheap, it's entirely possible that they just say "you're spending $50,000 on the printer and you're worried about $10 worth of plastic?"

It's not an extruder FDM. The Objet series are basically ink jets that print UV curable resins layer by layer.

No, this isn't filament. It's an advanced stereolithographic resin system. It's kinda like a 3D inkjet printer.

Now I can print me up a gun in color! Yee ha! (Translation for Brits: colour. You're welcome.)

âTranslation for Brits: Colourâ Er... Try pretty much the rest of the English-speaking world! Even in Canada it is officially spelled with a U. Be thankful we tolerate minority spelling; less so your plastic guns! :)

Nevermind the weapon. You know how they say there's a bullet out there with your name on it, I'll just print a bullet with my name on it and keep it in my pocket. That way I won't get shot because I won't ever shoot myself :o)

Not that big news (1)

When it comes to 3d printing, the big news will be the printer that can mix different METALS and plastics.

Frankly, plastics don't have the valuable electrical properties that we need for truly innovative design.

Show me a printer that can actually print itself - complete with electric motors and wires - rather than one that can print 'the non-electrical parts of itself'.

THAT would be impressive.

I think you need to think outside the box a bit. It doesn't have to be metal (although metal has some useful properties other than electrical)... Some plastics can be conductive, and certain conductive materials can be embedded into plastics and integrated into the 3d printing process...

Here's an example [plosone.org] of using electro-conductive carbon black in the 3d printing process...

3D Printed Helmet @ Home-- No Good (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.
