3D printers
 

So we just ordered this bad boy. It'll take probably 4-6 weeks to arrive here from Italia. Fast. Big build volume. Just about any material. So Excite. Besides all the protoyping we can no bring in house, we have all manner of stupid printer tricks we want to goof off with. It prints ceramic so.. I want to make a coffee cup that has a little ball in the thick air chamber walls of the mug to make a cool noise when you tip it up and also insulate the beverage better than a solid wall. Kiln kits are cheap.

Over the last year or so the number of bits we have printed for R&D has blossomed. Time to take the plunge.

much excite

And I am even more excited.

I had no idea such a thing existed.

The fact that an inexpensive printer is finally able to produce output which is directly usable rather than symbolic is a huge step towards becoming a "real" product.

I don't know why you're all excited over ceramic. People have been getting FDM printers to print all sorts of stuff for years now. It's nothing more than a syringe and clay.

Not to rain on the parade, but I expect less than stellar results from the fluid extruder. For one hanging a bunch of weight off a delta end effector with such a crazy center of gravity is literally the dumbest thing you can do to a delta printer. That combined with the extruded material, I doubt you'll get anything more useful than a coffee cup from it.

And I guess all the assembly jigs I have printed out of normal plastic on a $300 printer are just useless, yeap, useless novelties.

I expect better from Joe...

The ceramic capability is more of novelty for me. The real use is printing prototypes of the ****** ******* and billet ******* as well as the front ****** and matching ********. We have already use 3D printing for our billet coaxial perches for the NA, NB, ND, OEM spring adapters for the ND, 2.25" spring adapters, OEM NB top mount replicas and a few other production bits.

Utterly, utterly useless... :D


But on a serious note, I'm thinking more about the ability for ordinary people to directly create durable objects which are immediately useful in the real world. Not lost-resin casting forms or assembly jigs, but things like coffee mugs, buttplugs, pen bodies, prosthetic teeth, klein bottles, little porcelain cat figurines, shift knobs, that sort of thing...

I totally hear you about weight vs. structural integrity. I can certainly envision objects collapsing during the process. And yeah, it seems intuitively obvious now that we see it in action. But the fact that someone is finally attempting it in actual practice is cool as hell.

I mean, using fire to cook food seems like the simplest thing you can possibly think of, but it was revolutionary in its day. Homo Erectus!

Cool. Having an Enclosed chamber is nice.

I'd look into modding it to add controlled temperature chamber. It really really helps with larger parts to prevent warping with ABS. Stratsys owns the patent which is why you don't seen any of the cheaper 3D printer with that technology but the patent doesn't prevent you from moding a printer to get that feature. You just can't sell it is all.

take the exotic material printing with a grain of salt. you can print metal and wood too, but it's in a plastic matrix.

We have a lulzbot taz 5 at work. It's pretty awesome.

If I had to give advice, it would be: take your sweet time because you can't rush good 3d prints.

It can print metal and wood, too? Bitchin! Exhaust manifolds and antique prosthetic legs from the same machine!

Joe, you're really stretching out your coedeine+whiskey cocktail.

the materials are not REALLY metal or wood, they're more like ground up material stirred into a melted plastic and then turned into filament. They are probably slightly less strong than a standard 3D printed ABS part. But they do retain SOME of the properties of the original material--like conductivity or stainability.

Why you gotta be hatin' on Emilio's new gadget?

I was thinking the same thing, haters gonna hate.:eggplant:

We'll be able to work through R&D projects faster and more cost effectively. That is a very good thing. John doesn't think my ball in a coffee cup will work because the clay is wet when it prints so the ball will stick. Drat.

BTW, the company behind this machine is working on a huge multi story tall printer that takes locally found materials to make clay and print houses in 3rd world countries. Pretty cool too.

World's largest delta 3D printer could build entire houses out of mud or clay

[y8s] I'll bet the "clay" buildings are less strong than a steel-framed 100 story skyscraper constructed using conventional techniques. [/y8s]

:giggle:

I wonder if this guy has anything to do with that

Printing with concrete has been around for several years and it's just starting to make it's used in practical applications. What is unique about what wasp is doing is they are taking dirt that they find locally and figuring out ways to make houses out of it. Nearly no cost for the materials just supply power to the machine and it does the rest. Whether or not that ends up being practical, it is still a very noble pursuit and pretty cool besides.

+1 on temperature controlled chamber. Makes a huge difference in keeping big flat prints from peeling.

Heated bed is nice too.

Weed eater wire is a cheap source of nylon filament. You need to dry it out really well first, or you'll get steam voids.

will it run Ultem?

Not planning on any no-budget experimenting with mine. I think there are two schools on this forum for most endeavors be it cycling, modifying Miatas, guns, 3d printers; the lowest possible cost DIY solution and just buying something that already works.

Dunno about Ultem. Stratasys literature doesn't help you learn how to use it in your printer because they really want you to use it in there Fortus 3D system. Looks like our tip size and heat range would accommodate it though. We'll see. We are printing newbs so we'll try a bunch of materials. I expect there will be a steep learning curve for just making a good print. So many things that can mess it up as you start to work in large build volumes and special materials.

To me, additive mfg. really pays off when you can create parts tough enough for at least functional testing, and not just fit check. For FDM, I love ultem. I think you have to run hot to print it, but the parts are so tough. The material isn't cheap, but I find I end up replicating so much work when I start with abs, because it's so flimsy that it's more likely only going to survive fit checking.

fun!
