The TAZ 4 3D printer from LulzBot represents the latest evolution in high performance desktop 3D printing technology. This 3D printer provides you with a wide range of features that facilitate more consistent, higher quality prints than ever. The TAZ 4 features tetherless printing through an SD card with a versatile, multi-functional graphic LCD controller and boasts a spacious 11.7in x 10.8in x 9.8in print area with a controllable heat bed that can print large items, or many small items.
What can you print with? LulzBot users have many filaments options beyond common plastics like PLA, ABS, and HIPS. Exotic filament options like the rubber-like (NinjaFlex) materials can also be used with this 3D printer with the proper tool head.
All LulzBot products are Libre/Open Source Hardware, meaning you can adopt the latest and greatest technology being developed across the 3D printing market. From experimental filament materials and the modeling software of your choice, to new accessories like hot ends and print surfaces—experience the joy of user freedom! LulzBot's Libre/Open philosophy empowers you to download/print upgrades and replacement parts for your 3D printer, and make whatever modifications you want!
Note: Printing NinjaFlex, and other flexible filaments requires an optional print head found here.
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Well as the title says everything just works easy setup, I had my doubts on the bed leveling but leveled it once and haven't touch it since, just use their filament had a nozzle clog but it was my fault, used cheap filament and had a small artifact blocking the nozzle, the truth is that i highly recommend it. Excellent
Prints are impressively accurate, runs for long periods of time without slipping, and gives me the ability to print just about anything I can imagine/think of. I love this machine, it's a maker's wet dream!
That said, the design has some problems that the manufacturer is aware of and has taken some steps on. For one, the print nozzle is not good for PLA plastics - heat will flow up the PLA strand and melt it above the heat sink, causing a mess above the heating chamber. Lulzbot has fixed this with their newest all-metal print head (not yet available for purchase) with a fan across the heat sinks above the heating chamber, and you can make some minor adjustments to your own nozzle to fix this before you attempt to print PLA by printing a modified air funnel for the fan that blows both at the nozzle (where it does now) and across the heat sinks. Look for drawings on thingiverse and the lulzbot forums.
The other issue is that it has issues with large prints with ABS plastics and delamination. I've experienced this a lot myself, and it appears from my experiments that the hotter you run the ambient temperature, the better your print is going to be. Lulzbot has not yet addressed this issue, but the best suggestions I've seen thus far are to build an insulated structure around the printer and let the heat bed heat your print chamber. Print with this chamber closed, and you should have much better results with ABS. Personally, I'm leery about putting the electronics in the enclosure, so I'll attempt to re-mount as much as I can outside of the enclosure.
Also, be careful when printing with ABS - one of my early prints stuck to the heat bed so well it took a chunk of the PET tape (green surface of the heat bed) along with it. I still need to replace my tape , just haven't got around to it :(.
This thing is awesome. Taz has some basic config files for you to get going quickly and I really haven't had to change them much. It heats up pretty fast and once it's going I usually don't have to babysit it. You can also print right from SD but I had an extra laptop that I just leave plugged in to it. Plus having the laptop allows me to design on my desktop and then send the file to my laptop using DropBox. It's a pretty nice system. You get a tool kit with everything you need. I highly recommend the Taz 4 and LulzBot as a company. They stand behind their work.
