Tiretime 3D Printers in Nepal
The UP300 is superior ABS printing closed box design that contributes to the successful printing of ABS and other temperature-sensitive materials. It has better heat regulation from a closed box design as standard, HEPA and active carbon filtration for air purification and a removable bed for easy removal of the stubborn rafts. Tier time UP300 is sheet metal everywhere, resulting in a significant weight that helps root the machine to the desk. A necessity, given how aggressive the printer’s motion can be, especially in travel between extrusion paths. A monolithic box of a machine that as a functional office tool fits in, but by no means blends into the background.
Printer are provided with three material specific print heads. Designated “ABS” which comes installed on the printer, “PLA” and “TPU”, each head is broadly tailored to a group of materials. Respectively these are high-temp, low-temp, and flexible. Swapping the heads is a simple act of unplugging a ribbon cable from the installed head and unscrewing an M4 screw in the left-rear of the print head. Slot the new head into place with a satisfying snap thanks to a guide magnet, bolt in and ribbon cable up and that’s it. With each change of the print head and nozzle, some small configuration changes are required in Tier time’s UP Studio slicer.
A small selection of brass nozzles accompanies the UP300, giving greater choice in the possible applications using the different print heads. The standard 0.4mm for general high-quality printing in ABS and PLA is present as default on these respective heads. Nozzles of different sizes,0.5mm and 0.6mm can be used for flexibles and high-speed printing, plus a 0.2mm piece for high detail work. A modest build volume of 205 × 255 × 225mm is provided to work with on the UP 300. Underpinned this print volume is the UP300’s brace of removable double-sided print beds. One features a textured grip sticker backed with glass, tailored more toward lower temp materials like PLA and TPU. The other, with Tiertime’s signature perf board and, again, backed with glass, grips ABS like a briefcase full of cash. This latter board is a hallmark of machines designed for ABS, and on the UP300 it works exceptionally well. Amplifying the usefulness of these boards is their ease of removal from the machine, sliding out of their guiding clips.
Print preparation inside UP Studio is a straightforward, four print speed options are given as Normal, Fine, Fast, and Turbo. Specific parameters and adjusted settings are taken care of in the material profile manager. Printing using Fine the slowest and least likely to feature errors on the surface of the model. Turbo prints fast surprisingly, does not suffer from a drop in quality. Consequences for high speed is that belts skip on occasion, the fix transpired to be lubrication and lots of it on rods.
The act of printing in UP Studio gives you a relatively lean experience, choosing the layer height, print “quality”, infill density and whether to have supports and a raft. To make the minute adjustments needed for fine-tuning a new material profile requires you copy an existing material profile, define the profile’s baseline attributes such as temperature, filament density, shrinkage rate, and then add nozzle sub-profiles, each with their own sub-sub-profiles that correspond to the aforementioned print “quality” options. There currently aren’t any resources out there for downloading pre-tested material profiles. So in order to switch between materials often, be prepared to spend a lot of time honing profiles.
There are two options for correcting distortion in your prints on the UP300. The first is the XY/Z calibration, print out a baked-in STL which consisting of four “L” shaped towers. With a pair of calipers, measure various points of the print and input the findings into corresponding boxes in UP Studio that the UP300 then takes it as an offset for future prints. Alternatively, quick adjustment can be done by providing the expected dimensions of a print and the actual dimensions of the print which the UP300 can then also use to calculate an offset for subsequent prints.
