This is the best printer I could find for the money http://www.punchtec.com/

It's the Ord Bot Hadron. Very fast. I can print an entire AR lower at .2mm resolution in 8 hours, at 200mm/s. I can print with nylon as well, since the extruder is not lined.

Its also quite large and expensive for FDM/ME. Remember that increased speed = decreased accuracy, regardless of what the max resolution is, and running at a better resolution = increased time. 3DP is all about tradeoffs.

If everything else was equal, yes. If you want to compare screw driven, flimsy repraps to linear bearings and rigid frames... it's another story. It is not considerably larger or smaller than any other 200x200mm printable area model... and compared to anything else that's assembled and ready to print, it's not expensive. I wasn't interested in building a printer, I was interested in printing. I get great looking, dimensionally accurate parts. The only problems I've had have been with the QU-BD extruder.

If they can print with metals (maybe lower melting point type) that would be fantastic.

There are some relatively low priced (like, sub $15k) metal printers, but they are more for prototyping parts, and don't offer the machining tolerances and resolution your probably want in a production printer. It lays down layers of some sort of aluminum/plasticized binder and then laser cuts each layer to spec and starts on the next. Finished out by cooking off the plastic/binder and you're left with a 3D printed metal part, albeit a stratified, low-quality, fairly low-resolution metal part.

If anyone in the dirty south picks up a MakerBot 2, let me know. I will pay you to let me come over to your house and press the start button for you. Bam...made my own AR receivers, no firearm transfer in the mix. Wink

Using laser can melt however there are a lot of issues to be settled, there is a form of sand 3d printing especially when using such metals.

I am aware you can MELT copper, however there is sensible process for additively manufacturing with copper. Some people have tried it with SLS but its just.... no.... It doesn't work out too well and you need a KW laser. SLS machines are also not very office friendly due to the dust/atm control and lasers.



Not being office friendly is really an understatement Smiley
There are a few SLS machines in our lab, and you *could* put one in an office in a side room. The only real problem is hacking in the ventilation system.

Wow, that's extremely expensive stuff, you seen ExOne demo on titanium?  Their 3D Printers are at least 5 figures pricing.  You can get the cheapest ones from China, sub $1000 but that's only ABS and PLA.

Exone successfully printed in titanium I think that is 1,668°C .  But this will be specialized for industrial applications

I have personally built a reprap and mendel, not bad for 3d printing but I need to calibrate it once in a while to get it to print well. Fans in your room will affect the plastic build too, so make sure you keep the room air condition/wind/temperature in a "stable state".

If they can print with metals (maybe lower melting point type) that would be fantastic.
Directed energy deposition can. Types of binder jetting can but cheatingly using an infiltrator.

If anyone wants advice on specifics, machines, materials, limitations etc then pm me. Just finished 2 semesters learning from one of the most advanced additive labs there are.

Are you into 3D printer design using copper?  If yes I guess we can form a virtual team Smiley
I can't think of any method that could use copper. Copper's melting point is ~1100 and at those temps creates massive problems with oxidation which destroys its properties.

I am on a replicator 2 from Makerbot. The tech is bleeding edge, so get ready to spend some time being frustrated. Also, you need to know how to 3D model, or you'll be somewhat limited on what you can make. When I finally taught myself to 3D model and worked out all the kinks on my replicator2, I made some pretty amazing things, though. Currently working how to copper plate my models to make interactive 3D circuit puzzles. You should email Makerbot and ask if they will take Bitcoin, it doesn't hurt to ask does it?

I should say, though, a replicator two will run you in excess of 20BTC

Best,

Exo

There's a penny auction site which has listed a Cube® 3D Printer. I have earned $15 amazon.com gift codes but have never had anything shipped to me. So I don't know if they would be legit or not.

I checked Amazon yesterday, Cube is out of stock, I purchased directly from Cubify.  But there are definitely cheaper ones, you can built one for less than $500 at reprap.org but it took me 3 months!
