![]() Using a 3D modeling software on your computer or a 3D scanner, a digital file is where the three dimensional printing begins. In this way, 3D printing is a more efficient way of manufacturing while retaining the ability to create complex three-dimensional objects. On the other hand, subtractive manufacturing describes the process of creating an object by cutting out or hollowing out pieces from a block of material. The additive creation process describes the creation of an object through building an object upward with successive layers until the object is complete. I guess this is what people will buy this printer for, ABS and TPU.A 3D printer is a machine that is capable of additive manufacturing by way of creating three-dimensional objects from digital files. And quality is the same as with PLA, if it’s prints correctly. I just needed better bonding to glass, that’s it. ![]() With ABS, it is hard to stick, sometimes corners will be lifted, so I had a very bad learning curve, I was unable to print single model for few days, but after some time I got a hand of it. And I used one of the best TPU materials from Polymaker PolyFlex™ TPU95. TPU never looks perfect like PLA or ABS, and it also comes with 0.5mm nozzle diameter. With ABS and TPU is a bit more difficult. With sugar coating and 50C heated bead, it saves a lot of time on raft, and quality is just as good as Cetus3D MK2 or any other FDM printer. Just needs a little more pressure for touchscreen to work. Touch interface is very useful, after initialization you don’t need computer to change filaments, feed it into extruder, do nozzle calibrations and so on. With so much space they could include that, but I guess it has something to do with certification process, its easy to make it for 24V, it is harder to meat requirements when you have 220V mains inside. I am already designed board for this printer to take advantages on better stepper drivers.Īlso, power supply is external. You have space for improvements, if you want my help on this, just say so. Same goes for stepper drivers, it is nearly drop in replacement, just tiny modification in layout. In that case after initialisation, it will be dead quiet. As an engineer I can’t understand why whey cant make fan dependent on temperature (single if statement inside program) same goes for power reduction while it’s not doing a thing. It is adopted from other project, no question about it. Problem solved !Įlectronics for this it’s not great let’s say. Solution, I will cut Aluminum plate in the same shape, and bond glass to it. It takes ages to get up the temperature for ABS printing, while it‘s ok for PLA printing with sugar coating on glass. ![]() Turning to glass side makes things better, but thermal conductivity is not great. It uses thick PCB filled with holes, and i guess idea is that it will go into holes and grab very hard, but in reality it just fails for me. Removable glass plate for printing used good idea in theory but manifested ( at least to me) to a unreliable surface for printing. ![]() Debugging was unsuccessful, I can clearly see signal on main PCB that it’s shorted, but printer just keeps pushing Z up until calibration fail message. Mine was working, but after some time it started to fail. Nozzle calibration helps when you changing extruders, just change it, and press calibrate in touchscreen. Large build volume of 205×255×225mm, 50um smallest Z axis step coupled with 0.2mm diameter extruder, removable heated surface for ABS printing, touch probe for automatic build plate calibration, automatic height calibration, filament detection, limit switches on all axis, gates GT belts for low backlash and so on. It has everything: different extruders for different plastics, like ABS, PLA, and TPU. What is extremely cool about this printer ( and for 2099$ price I expect nothing more ) that it is pact with features that makes printing easy. This is mainly because they use very thick sheet metal for construction, around 1.5mm. (coupe problems) Shipping box was 61 x 56.5 x 60 cm, while printer itself is 500x523x460 mm and weights a ton (3.5>#span# right :D) with a total weight of 35kg Shipping box itself was 45kg and I was unable to take it home in my car, I had to take out printer out of shipping box and put it on passenger seat. Today I finally had some free time to take a closer look at UP300.
