3D Printing Plastic Not Sticking To Print Bed

My first 3D printer and I love it. The instructions are clear and it is easy to assemble out of the box. There are a ton of youtube videos on this printer so this has helped me a lot. What I found most valuable is to make sure you FIRST mechanically flatten the bed and then do the auto-leveling. I do an auto-leveling before each print because every time I remove a previous print I fear it moves the adjustment. Remember we are printing ~0.12-0.2mm layer heights so I think it is important to auto-level each time. It only takes a minute or two. Also do it with the bed and nozzle at the temperature you are going to print at.

The da Vinci Jr. 1.0 is a great bang for your buck with the decent build size of 6 x 6 x 6 inches and SD card compatibility. I printed out numerous projects so far and the print quality on this machine is fantastic. The only issues with printing is that it sometimes has trouble printing small details. However, this could be improved by changing the print settings in the XYZware, like making the extruder move at a slower rate, which decreases streaking. So, one of the most important features about this printer is its usability. Let me tell you right now, this machine will take you a while to set up properly. There isn't the three-knob calibration print bed that other 3D printers have,for this printer wants to be more approachable by maintaining a fixed, leveled print bed. The only thing you have to do is fix the Z Offset, which is the distance from the extruder nozzle to the print bed. This is the only calibration you have to do but it can be tricky getting it right the first few times. Unfortunately, not all of these printers were made the same, one printer could be printing excellent at .90mm offset, but mine functions the best around 1.65mm offset. This printer does 100 to 400 microns, and the infill and speed are all adjustable in the XYZware. I've printed out some quick decorations for my desk, but I've also spent a few hours printing out this model of the Statue of Liberty at excellent quality (100 microns) and slow speed at a 30% infill. The quality of the model was amazing. Overall, the 3D printer was hard, even frustrating at times to set up properly, but once it gets going it produces some of the best prints I've ever seen.

Love it. Easy to use; decent print quality. This is my first 3D printer and I am totally new to 3D printing. Glad I bought this as my first one as entry level.

Perfect for 3d printing filament.

NinjaFlex is a must try material for anyone serious about 3D printing, you will not be disappointed.

As a first time 3D Printer owner, I found this equipment to be very user friendly and intuitive. I especially like the automatic bed leveling and 7" display features.

A really good 3d printer! The removable bed is so much easier to remove prints than my old finder! Remember you must first calibrate the extruder and then level the bed. I would do this twice! Also set the auto bed leveling on. After that it prints great!

Solid brass reduces sticking like aluminum and plastic versions. Works perfectly. Thanks Heliopan!

Works as it should, lots of adjustments and the suckers are among the best I have used. Sticking to the plastic cover on roof top compartment of a Nissan Xterra

It was about 3 weeks without printing. I am so grateful to be able to print again!
