The Tiertime UP mini 2 3D printer was delivered in a great looking box and nicely packed with foam supporting all parts that were delicate or were not allowed to move during shipping.
After unpacking comes the set-up. For this you follow the Quick Start Guide that is included in the package. You first need to remove all foam cushions and protections inside the 3D printer. Then you can assemble the print head and download the software. After doing that you are ready to go.

Design & Specifications
To be honest, the UP mini 2 looks great. In my opinion, the fila station (the weird casing where you put your filament) is a bit over the top. But, it works. The 3D printer is fully encloses with outer casing made from plastic (also the station). This might make the UP feel a bit cheap when you open or close a door or replace a filament in the station. The inner casing however is of metal making it a solid frame. The door is transparent so you can watch the printing process, lit by LED lighting on the inside. It comes with a solid aluminium handle that you can extract for carrying the UP. This makes the UP a very portable 3D printer.

Software & Printing
The first thing I noticed when turning on the 3D printer was the great looking touchscreen. It gives clear instructions and is easy to use. Via this touchscreen you can initialize and calibrate the 3D printer to ready it for printing. Also, you can select the filament that you will be using. The printer then automatically selects the right temperatures for you. Furthermore you can look up all sorts of information about your print and settings.
I do have to mention that starting with the UP mini 2 did come with a few setbacks. Probably due to shipping, the vertical end stop was not working properly. This made the 3D printer jam when I tried to initialize it for printing. After consulting with the Tiertime helpdesk to figure out what was causing this, it became clear that the end stop was causing the problem and needed a small adjustment I could do by hand. After bending it a bit in the right direction, it worked properly and kept on working like it should.
To prepare models for printing, you’ll need to download the Up mini 2 app. You can do this on their website. You can easily upload your STL files in the app and ready them for printing. Ones you are done with setting up your print (selecting the infill, layer thickness and desired print quality), you select the print option and the software begins with slices the model before sending it to the printer.
Here I ran into my second problem, WIFI connectivity. No problems connecting the 3D printer to my network but problems started to happen when sending files from the app to the 3D printer. I received connectivity errors and when I succeeded in sending a file, the print failed halfway indicating an error in the file or joggle error. I contacted Tiertime about this and they said that this was new problem for them, they are looking in to it to fix this problem.
A solution for me was to simply connect the 3D printer via the provided USB cable. Ones the printer was connected with the app via USB, it was very easy to send files successfully. After these few setbacks, the first printing results amazed me.
For my first successful print (after connecting with USB) I chose to print a benchy to see how well it does compared to other printers. I was positively surprised by the quality and detail this 3D printer was capable of producing. I set the layer thickness to 0.15mm (highest quality). In the UP Studio software you can choose the infill, support, layer thickness and you can do a lot more finetuning.
After the benchy print I did several other prints and also a torture test meant to push your printer to its limits. The UP did a pretty good job on that print. I even tested the stop and resume function of the UP in the middle of this print. [When you open the door the printer stops automatically, if you close the door you get the option to resume the print] If you look closely you can see the slightly burned plastic in the bow, that is the only mark that the printing pause left on the object.
The Tiertime UP mini 2 has a retail price of $599USD at the moment. If they fix the minor software problems and truly make this printer plug-and-play, $599USD is a more than fair price for the quality you get when buying the UP 2.
