And here it is the long awaited new version of the Sunlu dryer, or the Sunly Dryer S2.
Will it be able to amaze us and surpass the quality already achieved by the old model?
You will find out by reading this review!
Sunlu presents this new dryer with an impressive campaign on the well-known crowdfunding site Kickstarter:

At first glance, what most catches the eye is the completely revised and redesigned new design: curved and futuristic lines, a large front touchscreen display surrounded by a futuristic “multicolored LED circle”, 4 non-slip feet at the bottom.
But it is inside that it shows perhaps one of the most important innovations from a functional point of view, namely the resistive “strips” that cross the entire internal circumference, dramatically increasing its efficiency: much appreciated because it leads to a uniform distribution of heat.
Let’s examine the display and its features:
It is possible to manually set the desired temperature as well as the “cooking” time and also the big news is the presence of some presets suggested for the various existing materials: PLA, ABS, PET, PC, etc …
Everything can be changed using the comfortable touch buttons at the bottom of the display.
There is also a humidity sensor that shows its value on the display, top right: in this way we will know the percentage of humidity of the filament in real time.
Trials
As with the “old” model, we made some tests starting from a filament full of moisture.
The first test is the print of the classic Temp Tower and the results are not good at all:
As you can see, the print has a lot of stringings, practically at any temperature: from 190 to 230 degrees.
Presumably the lower temperatures should have given a little more encouraging results: evidently the humidity level was so high that the temperature did not affect the final result in the least.
We take note of it.
At this point we inserted the filament into our Sunlu Dryer S2, following the specifications to be used for the PLA. And here is the result:
The photo speaks for itself: the difference compared to before is truly remarkable: now the only points where there are stringings are only those where the temperature is higher and it is still a predictable result.
What is truly disconcerting is that the filament appears to be totally reborn!
Compared to the old model, apparently the new Sunlu S2 Dryer really makes a difference!
We then changed filament, this time using a blue PLA, which was even worse than the previous one.
Here are the first prints:
Again, the stringing problems are evident on the 3DBenchy, as well as on the flow calibration cube, on the right.
Also in this case we have inserted the filament in the Sunlu Dryer S2, following the specifications of the presets. And here are the results:
What to say? Abyssal difference !!!
Conclusions
The Sunlu Dryer S2 really marks the turning point from the previous model.
But not only in the beautiful design and in the generous touch display, but above all in the final result, which is the most important thing in a product like this. How many reels have we thrown away? Well, with this product you will no longer need it!
