The Pro version of Uniz Slash is equipped with UDP technology which is specially developed by the manufacturer. It enables users to print parts and functional prototypes at a very fast speed. An adult’s shoe hole can be printed in less than 40 minutes.

The feature that is more advanced in this printer than its predecessor is the Z-axis build envelope.

There is a specialty of every Slash printer manufactured by Uniz. They can share all the five types of functional resins that can deliver high-resolution prints in the build volume.

Though there are some restrictions in printing with this printer in the UDP mode, like Uniz’s specially engineered resins only work during this more. These resins are formed for giving you the highest quality prints that showcase the finest details in your designs.

Resins of this printer create highly accurate and robust parts and functional prototypes that are ideal for industrial-grade rapid prototyping and product development.

Uniz Slash Pro 3D Printer

Uniz Slash Pro is an efficient solution for individuals who need the extended build envelop that the company has constructed in this desktop’s setup. Uniz released four other printers with Slash Pro in the same year that meant to target four different sectors of industry. They were, Slash+, Slash OL, zSLTV 15, and zSLTV 23.


As hinted in the introduction above, there are two modes that this printer can be operated on. Both of them work using the principle of LCD Stereo Lithography technology in which a photosensitive resin is cured by a light source.

In normal mode, Uniz Slash pro uses normal resins, whereas, in UDP mode, the printer uses special resins that are developed by the company. The light source, which in this case is LCD is contained in the tank and is cured against the build platform of the printer.

Although you have printers like Phrozen Shuffle XL which uses the same mechanism of moving only along the Z-axis, in Uniz Slash Pro, it’s the doubling of the movement that lets it achieve similar or high-quality prints in lesser time.

The machine comes with automatic level control and its software allows users to create smart supports for models. The result is better quality prints in no time. Let’s take a look at features one by one.

Uni-Directional Peel Technology

Uni-Directional Peeling is a result of attempts that have been made in the past to innovate the high quality of producing SLA technology. Consumers of 3D printing who did business on a small level worked only on FDM 3D printers until the invention of SLA.

After the invention, they started working with FDM as well as SLA, but SLA in a lesser amount. Though SLA gave them the quality that FDM never did, it did not produce a part of a prototype at the same time as FDM did.

This problem was noted by manufacturers of SLA printers and an urge to address this problem correctly was started. Uniz, being one of those manufacturers came up with this uni-directional peeling technology.

Here, by reducing the up-and-down peel to only one-directional peeling, it was able to free the SLA 3D printing market of the speed restrictions. With a printing speed of over 700mm/hr on the z-axis, UDP technology shook the market.

Automatic Level Control

When printing continuously, the level controlling of the print bed and the base, as well as the height adjustment of the distance of the light source from the resin has to be done faster. Doing this adjustment manually demands a lot of effort when continuous printing one after the other part.

The makers of this printer have kept this in mind and introduced this feature of automatic leveling. After every print, the print bed would be leveled according to the next print.

Carbon Fiber/Steel Reinforced Frame

Being an SLA desktop 3D printer, normal complaints about it is that the printer does not stay stable during the printing process. Especially while parts and geometries to be printed have a build volume in the range of the maximum build volume that can be printed in the printer.

If the frame of the printer is as strong as Unit Slash Pro’s is, the problem of vibration during the print process or the printer not remaining stable, vanishes.


Uniz Slash Pro works on LCD Stereo Lithography technology. The printer’s build volume is 192 mm * 120 mm * 400 mm. XY axis resolution of this printer is 75 micrometers and the layer resolution range provided by this printer is 10, 25, 50, 100, 150, 200, 300 micrometers.

The printer can be run on two printing speeds i.e. 600 mm per hour on the UDP mode and 200 mm per hour on the Normal mode. The printer’s dimension is 350 mm * 400 mm * 730 mm. The operating temperature range of this printer as suggested by the company is 18 degrees Celsius to 28 degrees Celsius.

The power requirements for this printer are 100 to 240 Volt, 6 Ampere, 50/60 Hertz, and 480 Watts.


$4499 is the market price of the printer. Now for all those who are wondering how come this can be the price of the desktop printer! Well, looking at the list of features and the amazing speed that the printer can deliver, Uniz Slash Pro would hardly be judged as unsatisfactory in terms of the quality work that it delivers.

So the price is not at all higher than printers which deliver the same amount of quality work, instead, it’s lower.

First Impression

Completely black in colored, the printer takes away your eye’s attention to the table on which it is kept. The right side of the printer has a bottle type structure for keeping the resin, and there is an opening that lets you see the mechanism of the printer from its front view.

Opening the lid and you will see the mechanism based on which the one-sided peeling happens in the printer. It’s the Z-axis build envelope and doubled in size than in its predecessor.

The LCD light source is at the bottom and it produces light rays in a much denser way than in other SLA printers. The outer body is made of carbon steel reinforced.

When you open the lid, you also get to see the resin tank which can be opened from the bottom left. Notice the company’s logo at the bottom when the printer is viewed from its front view, it is the start button.

The area is at the bottommost of the printer is the place from which air is allowed to tuck in. After the printing of parts is done, the cooling is done using this area. The adjustable leveling screws are present just beside this area.

There is a level sensor by which the print bed can be automatically leveled at the right bottom, when the lid of the printer is opened, at the inside body.


The printer comes fully assembled. All you have to do is read the manual that the manufacturer has accompanied with the printer in its packaging. After unboxing you’d have to place the printer on a platform and adjust the adjustable screws which are present on the right bottom of the printer.

These screws help you level the printer if it’s slightly tilted. You also have the level bubbling situated at the center of the build platform. Whenever the air bubble is centered; the printer is on its level.

After adjusting the screws, you’d have to tilt the resin tank which is present at the inside body of this printer. Tilting it to exactly 30 degrees would let you insert the rear fixed locating lugs into the holes present at the back end of the LED.

Then you’d have to push the resin tank downwards nearer to the LCD panel and push the lock catch to tighten the resin tank.

The build platform comes separate from the printer. Keeping the metal surface of the build platform downward you’d have to make sure that the locking arm of it is opened and then push. After pushing the platform you’d have to pull the locking arm clockwise and lock the build platform.

The next step is inserting the resin cartridge. You’d have to remove the bottle, clean it, insert the resin inside the bottle and the bottle inside the slot and ensure the needle punctures the rubber cap.

The last step of setting up the printer is installing the liquid level sensor at the right bottom of the inside body.

Printing Type/Cost

The infill percentage of parts and prototypes that are printed using Uniz Slash Pro is higher than its competitors. The cost of resin that can be printed using the UDP Mode of the printer is high. The Z-axis travel is double that its predecessor.

And the printer is known to consume more electricity. Most of the factors that contribute to the printing cost of the printer are at the higher end so the overall printing cost is something that you are going to find higher than other printer’s which give close competition to this one.

Print Quality

Uniz Slash Pro is an LCD 3D printer. These 3D printers are known to use an array of Ultra Violet LCD rays as a light source. These light rays come from the flat LCD panels shining directly, parallel to the build area.

Because these light rays aren’t expanded much, the pixel distortion is not an issue with Uniz Slash Pro. The print quality of this printer depends on the density of the LCD rays. The denser they stay, the more quality work they are known to produce.

Uniz Slash Pro has more pixels and in turn, a better print quality. And the fact that the printer can maintain this quality, yet produce parts and functional prototypes faster than others, is the add on benefit.

In Uniz Slash Pro, the entire layer is flashed at one, instead of single-pointed flashing. This enables it to produce print speed, never seen before.
