Prints with a variety of filament types. Accepts third-party filament spools.

Microsoft Visual Studio 2005 Pro Final Dvd Iso Torrent. Easy to remove finished objects from print bed. Supports open-source hardware and software.

• Cons Uneven print quality. Involved setup process. Does not include filament. Open frame increases risk of burns from a hot extruder. • Bottom Line The LulzBot TAZ 5 is an open-frame 3D printer capable of printing relatively large objects from a variety of filament types. The LulzBot TAZ 5 3D Printer ($2,200) is a large and versatile 3D printer that can print using a variety of filament types and several software packages. Aleph Objects, which makes the printer, describes it as reliable and low maintenance, and that proved to be the case in our testing, as it successfully printed out every object we tested it with, on the first try.

The only other 3D printer we've tested that achiever this feat is the, our Editors' Choice for makers and designers. Alas, the TAZ 5 couldn't match the Ultimaker's print quality in our testing, but it's still worth considering if you need to print larger items. The black, steel-framed LulzBot TAZ 5 is a large machine, measuring 26.8 by 20.5 by 20.3 inches (HWD). Its frame is unusually open, with no door, sides, or top. Its build area of 11.7 by 10.8 by 9.8 inches (HWD) is the largest of any 3D printer we've tested. It's wider than, but not quite as tall as, the, whose build area measures 12 by 9 by 8.9 inches (HWD), and larger than the Ultimaker 2, our Editors' Choice high-end 3D printer (8.1 by 8.8 by 8.8 inches, HWD). Resolution ranges from 500 microns down to 50 microns, where a micron is.001mm.

The print bed has a PEI (polyetherimide) thermoplastic surface, which requires no maintenance but can be heated before printing to prevent the base of the object being printed from curling. Both the print bed and the extruder assembly are positioned on moveable, motorized carriages. The print bed moves on the Y axis (in and out), while the extruder moves on the X (side to side) and X (vertical) axes.

The TAZ 5 can print from a computer over a USB connection. There's also a slot for an SD card, from which you can also print using the monochrome display and push-dial control. Setup In marked contrast to my experience with the LulzBot Mini, setting up the TAZ 5— between unboxing the printer, assembly, and calibration— was unusually onerous. Assembly includes attaching the printer bed and Y axis assembly to the printer frame, mounting the extruder tool head, plugging in the electrical connectors for the motors as well as four connectors that attach to the power supply, attaching the filament guide and loading the filament.

Calibration includes setting up the Cura software, aligning the X,Y, and Z axes by moving the extruder with the software and adjusting set-screws, and leveling the print bed. As detailed in the quick-start guide, setup is a 25-step process, including attaching and loading the filament. Although some steps include illustrations, there's no visual glossary of parts, and more than once I found myself puzzling over what exactly an idler bolt or some other part mentioned in the guide was. That said, after several hours I got the printer set up without any serious mishaps, performed a calibration test, and started the first print. The involved setup process makes the TAZ 5 poorly suited for 3D printing newbies, though.

Filament The LulzBot TAZ 5 takes 3mm filament, the thicker of the two common sizes (the other being 1.75mm). The printer works with a range of filaments that goes far beyond the acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) typically used in 3D printing. We printed with high-impact polystyrene (HIPS), the filament that Aleph Objects recommends for this printer. (The only filament normally included with the TAZ 5 is a 1-meter test length of HIPS, good enough for printing one object, but our test unit came with a full spool of HIPS as well.) It supports ABS, PLA, HIPS, polyvinyl alcohol (PVA), wood-filled filaments, Tritan polyester, polyethylene terephthalate (PETT), bronze- and copper-filled filaments, polycarbonate, nylon, conductive PLA and ABS, UV luminescent filaments, plasticized copolyamide thermoplastic elastomer (PCTPE), and PC-ABS. Although the menu lists just HIPS, ABS, and PLA, LulzBot lists extruder and print-bed temperatures for the more exotic filaments on its Web site, and provides downloadable software settings for them. Software The LulzBot Taz 5 as well as the LulzBot Mini are made by Colorado-based Aleph Objects, a company committed to Libre Innovation, which means the hardware and software it creates is free to be copied, modified, and converted by all users. From the Aleph Objects LulzBot site, you can download the Cura open-source software package for Windows, OS X, or Linux (Debian, Ubuntu, or Fedora).

You can also download two other 3D printing programs, Printrun (a printer host program for controlling the printer) and Slic3r (a slicing program that converts a file into layers based on the chosen resolution and saves it in G-code format in preparation for printing). I used the Cura package for our testing.

The Cura LulzBot Edition software package is very easy to use. When you open it, a representation of the print bed appears on the screen. At the left edge of the screen is the QuickPrint menu, which lets the user set a resolution: High Quality Print, Normal Quality Print, or Fast Low Quality Print. You can choose between ABS, HIPS, and PLA filaments. You can add print supports to hold overhanging parts of the object in place during printing, or a print brim, a thin extension of plastic around the base to help secure it. Along the top of the screen is a pull-down menu with items named File, Tools, Machine, Expert, and Help. The easiest way to get printing is to press Load Model, the leftmost of two buttons in the upper left corner of the screen.

It will call up Windows Explorer (aka File Explorer) to let you access any 3D-printable files on your system. Once you've chosen and opened one, it will be shown to scale on the virtual on-screen print bed. Then you press the second button, Control, which brings up a dialog box from the Pronterface 3D printer control interface, which is incorporated into Cura. When the computer is connected to the printer via USB cable, you can use the control panel to heat the extruder and build platform to the desired temperature for the plastic. Once it's hot enough, you press the Print button at the top of the dialog screen and, once the build platform is calibrated as described below, printing will commence.

When the job is done, the printer will cool down, and you can remove the object from the build platform. From the Expert tab, you can access Full Settings, which lets you set extrusion speed, layer height, and a wide range of other settings. Printing I printed close to a dozen test objects with the LulzBot TAZ 5, one at the Cura setting for High Quality Print resolution (180 microns), and the rest at Normal Quality Print resolution (250 microns). Neither is particularly high; in fact, the TAZ 5's High setting is lower resolution than the Ultimaker 2's default resolution (100 microns). That said, you can use a custom resolution value as high as 50 microns.

As resolution is a measure of layer height, the lower the value, the higher (or finer) the resolution. The LulzBot TAZ 5 printed out all our test objects without a single misprint. Print quality was a mixed bag. Although some objects printed well, others showed layering and had a slightly ropy look, especially on top. Some surfaces looked rough-hewn. It did worse than usual in resolving fine detail in one test.

Overall print quality wasn't as good as that of the Ultimaker 2 or Ultimaker 2 Extended. Many 3D printers eschew a door or hood to provide easy access to the extruder and print bed. The LulzBot TAZ 5 takes this a step further, lacking door, sides, or lid. You'd best use the printer in a well-ventilated area, as some people complain about the odor of burning plastic, most notably with ABS. Also, be careful to set the printer up in a place that's out of reach of kids and pets.

Conclusion The LulzBot TAZ 5 is a large, open-frame 3D printer geared for use primarily by professionals and hobbyists. It lacks the easy setup of the LulzBot Mini and Ultimaker 2 series that would make it a good fit for a general audience. It can print large objects, and proved reliable in our testing. Print quality was erratic, but even the high-resolution setting in Cura is relatively low compared with most other 3D printers we've tested.

You might be better off using a custom setting of 100 microns or higher, though this adds to the print time. Priced between the LulzBot Mini, our top midrange 3D printer, and the Ultimaker 2, our top high-priced model, the LulzBot TAZ 5 3D Printer is capable of printing larger objects than the latter and has a slightly larger build area than the Ultimaker 2 Extended. Setup is far more involved than either of these models, but it is a dependable and versatile printer, and although its print quality was a bit uneven in our testing, it would presumably fare better using the higher resolutions that custom settings afford, at the expense of longer print times.
