The Peachy Printer.... 3D printing for $100

This is hilarious... but it shows you the power of crowd-source funding, if you have a good idea...

His goal was to raise $50k...
as of writing, he's already got >$500k (that's right, an extra zero)...

Overly complicated version of something that already exist. I cant say i support this.


They have 3D printers that can use metal powder cartridge , like aluminum and titanium.

Nice, but how much are those "pro" printers?
The Peachy is geared to people like you and me who want to tinker with prototypes (well... maybe that's not you )

Granted, this is only the beginning; the future is still wide-open with only innovation, impetus and capital standing in the way.

well the ones that print with metals are 10+ grand. They are used for prototyping and testing before spending millions on new machining equipment to produce a new product.


THe plastic printers you can get for less then 1 grand nowadays.

Also if you are good at programming you could pick up some servomotors and make one with a hot glue gun.


Hmm i think i just fond my new weekend project.

You're going to need a fine tip unless you are working with a 5mm tolerance. As for programming, I suck... I learned some rudimentary C# 20 years ago... and some assembly code for the HC11 MCU... I just got into the Arduino in the last few months, and trying to relearn basics...
Is there a particular language you'd recommend if I could only choose one?

Can't support it? No need. They are 10x over in fund raising. 3D printing. The breakthrough is the cost. You can pay $50K, $150K, or $500K.

Now you can pay $500. Such a deal but it won't print metal. The printing material gates the cost of the printer. This is not a laser. But, structual ABS works very well for many things.

OTH, college kids are printing orbit capable rocket motors. A Brave New World. Space is a killer.

C and C++ plus Java.

Yah... I found my old C++ Turbo textbook (Structured C for Technology by Tom Adamson --1990)... I assume the language is still similar to what it was 20 years ago, correct?
In fact, just scanning through it, it's very similar to the Arduino programming language.

I figured Java was important, too... thanks for the input...

You at the end of the era. The world is moving to the C-2011 standard, but, not a big change. And being in compiler science for a living, I can tell you the hot new thing is called the Lambda function. It allows a function to be stated on the fly. Like inside a loop, so all the variables are declared local by default. Mem alloc can be tight, etc.

But, yes, one language is the same as the other really, in that there is a finite number things that can be done, or need to be done. And that is based on usage. Many, many languages still exist in the corners but these are the clear winners. Remember, coding is a concept. Which language is the tool choice.

C11 for everything but tied to one processor type, only

C++ if you need objects, to keep big code organized, for native processor consumption

Java for everything, all processors, but not as swuuuft as native compiled code

I find Arduino ridiculously powerful. It is reduced instruction set C syntax. BTW, The problem with engineers is engineers...don't I know it. All languages are just stupid full of overlap and slight variations. Beyond UN-necessarily complex for very good reasons. Job Fair for PhDs.

If you can't figure it out with the few loop constructs, no INDEX and a minuimun of put and get actions, you are not thinking, keep it simple. You don't get a roomful of supercomputer in the palm of your hand. So, you don't have the luxury of bells and whistles. OTH, the simple frame work can lead to outstanding solutions, easy to code.

Go play with the IDE and code samples. I have one running a PID loop that reacts to room temp by changing the direction on a fan. Maybe 40 lines of code.
