Uniz Slash Plush vs Formlabs Form 2 (2021)

Good day!

We decided to compare two popular UNIZ Slash Plus and Formlabs Form2 photopolymer printers .

Slash Plus uses LCD stereolithography technology, while Form2 uses classic SLA method for illumination. Both methods produce amazing accuracy at a fast enough print speed, and also promise a smooth, monolithic print surface.

Printers have found their way into areas that require maximum precision and detail, such as making dental aligners and models, medical demo models, jewelry making, design and master model printing.

Brand resin price 5200-13000 rub / 0.5l 14300-38000 rub / liter
Consumption of photopolymer cans (1l) Over 17,000 layers 1,000-3,000 layers

We print the same dental models with a resolution of 0.05 mm.

Slicer in Form2 calculates time 6 hours 21 minutes for 4 parts. Using simple arithmetic, we get 1 hour 35 minutes to print 1 model.

The Slash Plus printer slicer gives a more optimistic forecast: 6 models will be printed in 1 hour and 28 minutes, for a total of only 14 minutes per model.

Slash Plus also beats Form2 with a good timing advantage in printing masterbatch rings. The layer thickness here is 0.025mm.

The Form2 printer will take 11 hours 22 minutes to print 55 models, for a total of 12.4 minutes for one ring.

While Slash Plus will print 60 patterns in just 3 hours 51 minutes, and one ring in 3.8 minutes.

In total, while Form2 is printing one ring, Slash Plus will already finish 3 of the same.

Now consider printing a 10cm * 10cm * 10cm cube with a resolution of 0.1mm.

The Form2 printer takes 39 hours and 18 minutes to print, compared to the Slash Plus in 3 hours 51 minutes.

But the resin consumption of Form2 is significantly lower and amounts to 25.9 ml / h, in comparison with the Slash Plus, which has a consumption of 256 ml / h.

Outcome

The Slash Plus printer confidently surpassed Form2 in many respects. In particular, it has almost 1000 cm³ more volume of the construction area and almost 2 times more accuracy. In addition, the Slash Plus has a customizable Z-profile, i.e. different areas of the same model can be printed at different resolutions. Empirically, we found out that Form2 lags far behind in print speed, but at the same time it uses much less photopolymers. This is important, especially considering that Formlabs’ branded photopolymer is significantly more expensive than Uniz photopolymer.

Considering the capabilities of 3D printers, both of them are perfect for solving both business problems and for private use. Both have a fairly wide connection interface, the ability to work with cloud data storage and heavy files. However, if you have to print a lot and use several printers at the same time, then Slash Plus can provide more convenience, as it allows you to print with several 3D printers from one slicer.
