Faster cheaper ($700) large 3D printer

[MitchJi]

Hi,

When a group of college students couldn’t get access to an affordable 3D printer at their schools, they didn’t let that get in their way, but instead built their own, and the resulting version ended up being faster, more efficient, and a fraction of the cost of other 3D printing options.

The 3D printing device developed by Shai Schechter, Andrey Kovalev, Yasick Nemenov, and Eugene Sokolov, dubbed Deltaprintr, could be a major gamechanger in prototyping and quick fabrication, and based the success of its current Kickstarter campaign, is well on its way to blockbuster status with makers of all stripes.

$685 assembled, vs about $2000 for a new MakerBot 3D printer, it has a number of other benefits:
Faster speeds
100 micron resolution
Automatic calibration – no more manual calibration
Ease of use and assembly
Large and easily expandable print volume
PLA plastic – biodegradable and food safe
LCD and SD card included
Compact power supply

The Deltaprintr frame is expandable to accommodate larger jobs, uses 65lb Spectra fishing line instead expensive belts (which can occasionally skip while printing), and is not only made of fewer parts than other 3D printers, but those parts are also more universally available, making it easy to customize.

We engineered the Deltaprintr to be simple, efficient, and affordable. We want as many people as possible to be able to get their hands on this exciting new technology without having to sacrifice quality or user-friendliness.

Why Deltaprintr?
Simple – Using a 3D Printer shouldn’t be a hassle. We designed our printer so that it requires minimal set-up, and so that there’s effectively no long-term maintenance. We’ll be shipping every printer with a construction manual (pictures!) to get you up and running in no time.

Efficient – The polar coordinate system allows for faster movements (than those of traditional Cartesians printers) while achieving a 100 micron resolution.

Affordable – Because a Deltaprintr design doesn’t need as many parts as other 3D printers, we can pass the savings on to you.

About the Deltaprintr
The Deltaprintr uses three stepper motors, located under the acrylic build platform, to control the carriages that move the hot-end. Both the drive reels and the bearings that the carriages ride on are manufactured via high-precision CNC machining.

The minimal carriage design allows you to simply slide the assembled carriage onto the extruded aluminum beams without having to make any adjustments. The Deltaprintr also uses 65lb Spectra fishing line instead of expensive belts to control the carriages. The Spectra line also makes it easy to expand the build volume - all you need to do is buy longer aluminum extrusions, which cost a few dollars.

Every printer will be fitted with an automatic calibration probe, ensuring that prints stick to the bed and don't warp when printing. In addition, every printer will also come with an LCD display and a compact 60 Watt laptop-style power supply.

THIS...is AWESOME!!

Totally cool!

I'm thinking that this is the beginning of price drops/wars, which is great for us!

these repraps are good,

But that kickstarter projects printer is awfully slow, my printer uses upto 7 amps at 15 volts... that's without the heated bed, "i have very smooth operation" but yeah cheaper to start off with, and pla is a great plastic to use to begin with as well.
these days i would be going for a printer that can easily do 200mm's infill speed with lots of acceleration, also ideally a heated bed and if possibly a heated build chamber, but none make them with heated build chambers because i believe its in direct violation of one of stratasys patents..

I still believe these are fairly simple machines and people with some spare time can build them for cheaper and better than most ones on the market.

This guy did not calibrate, he used cad calculations to punch into the firmware, pretty good.

Compare it to this speed 180mm's , Note that first layer is normally 30% speed, " watch 30 seconds and then skip to 1.40 in the youtube video to quickly see the layer change and the speed change

Can you buy the Rostock assembled?

I always wonder which one uses the best material for printing parts...

So could a heated build chamber be like placing one of these printers in an oven at ~50 degrees C?

yeah you can buy them, a fair few places sell them, but $700 is a good deal. The ones i have seen are a bit bigger i believe.

you dont need a build chamber until you start using nylon, or wanting to print big parts with tight tolerances.
