GK TWO Build Plate Levelling

Upon unpacking the box, I was pleasantly surprised to find that the build plate on the printer is already expertly levelled. The innovative build plate system is uniquely designed with eight screws for precise adjustments, but without any screws needed to fasten onto the z-rod mount, simply slide into place and it locks into position with a catch making it incredibly easy to use.

To level the plate, I simply need to loosen the eight screws on the top of the plate, adjust it to the desired level, and lock it back into place. I must say, this is a much more convenient system than what I have used in the past, and I appreciate the time and effort saved by having a pre-levelled build plate.

Another feature of the build plate that impressed me is the anti-drip lip design. When I turned it over to rest, I expected some resin to spill, but the lip was able to contain any drips, ensuring a neat and tidy workspace. This really speaks to the attention to detail and user experience that the creators of this printer have put into their design.

Overall, I must say that the build plate on this printer is a game-changer. Its simple and practical design, coupled with the pre-levelling and anti-drip features, make it a personal and professional choice for anyone looking for a hassle-free printing experience.

A Quick-release Vat System

One of the standout features of the GK TWO printer is its unique resin vat docking system. As someone who has worked with different printers in the past, I can confidently say that using the GK TWO was much more efficient and streamlined. Instead of fumbling with bolts on either side of the vat, simply slid it into place and it locked securely into position.

Another impressive aspect of the GK TWO’s resin vat is the use of high-quality NFEP film, which is available on Amazon in various sizes. This material not only produces better quality prints, but it also has a longer lifespan compared to other film types. As someone who values quality and durability in my work, this is definitely a feature that I appreciate.

When it comes to changing the NFEP film, it’s a straightforward process that is similar to what I’ve experienced with other SLA 3D printers. I just needed to undo the screws underneath and replace the old film with a new one. It is simple, quick, and effective.

Overall, I have to say that the resin vat system on the GK TWO is one of the most user-friendly and efficient that I’ve worked with. The use of high-quality NFEP film is also a major plus that ensures the longevity and quality of my prints. As a professional, I value equipment that is both effective and easy to use, and the GK TWO delivers on both counts.

UniFormation GKtwo 10.3-inch 8K Resolution Screen

The UniFormation GK TWO 8K 10.3 LCD screen! As a proud owner of this device, I can attest to the high-quality performance it delivers. The increase in size and resolution from the previous GK ONE model is a noticeable improvement, and the matrix parallel light source provides an impressive HD display with a resolution of 7680 X 4320 and a XY resolution of 29.6 microns. The addition of an upgraded anti-scratch film on the LCD screen further protects against any potential FEP and resin-related mishaps. Overall, I highly recommend this screen spec for anyone in need of a dependable and high-performing SLA printer.

As someone who has worked with various printers in the past, I can say that this front control panel is one of the best I have seen. The screen is incredibly user-friendly, featuring a wide variety of controls that provide easy access to all the printer’s features. I particularly appreciate the clear and responsive design, which makes navigating between different settings and options effortless. The touch screen is packed with an extensive range of controls, allowing you to adjust everything from heating and exposures to vat cleaning and printing. Whatever you need to do, this screen makes it simple and straightforward. I appreciate how well thought out the options are, which makes printing with the GK TWO a breeze.

Additionally, I must emphasize how well-designed the format is. It’s obvious that the developers put a great deal of time and effort into creating a screen that not only looks great but works well in the hands of professional users. The interface is clean and uncluttered, which makes it simple to find what you’re looking for and adjust settings as needed.

Automatic Heating System

As someone who has been 3D resin printing for quite some time, I’ve always wanted a resin printer with a built-in heater, especially living in a cooler climate. So, when I got my hands on The GK TWO, I was thrilled to see that it had a built-in PTC ceramic heating technology that can warm up the printer to (95℉) (35°C) in 8 minutes if the existing ambient temperature is at 50℉.

The printer has three temperature settings (77℉,86℉,95℉) (25°C,30°C,35°C) that start to heat up the printer before it allows you to print. Additionally, the temperature is displayed on the front screen, and you can adjust it to your desired temperature (25°C,30°C,35°C). With these features, I can continue printing even during the colder months.

Integrated Air Filter System

Let me start by saying that the integrated air filter system on the printer is a game-changer for me. As someone who has struggled with resin fumes during printing, this feature is an absolute lifesaver. The system itself is located at the rear of the printer and utilizes a fan-driven carbon filter. Even though the filter is a decent size, it does an excellent job of filtering out resin fumes during the printing process. I also love that there’s no need for charging since the internal case fan drives air through the filter.

Additionally, the filter locks into place, so you don’t need to worry about it falling out or being dislodged during use. While replaceable filters are available, they can be a bit costly. However, considering the benefits of having the filter system in place, I believe it’s totally worth the investment. The filters are effective at filtering out harmful particles, reducing the number of harmful substances created by the resin and printing procedure by more than 50%. As someone who values safety and health in my work environment, this is undoubtedly a feature that I appreciate.

One thing I noticed right away when using the integrated air filter system is that the printing smell was significantly lower than usual. This made my work environment more comfortable, and I felt reassured knowing that I wasn’t inhaling harmful fumes. In short, I would highly recommend the integrated air filter system to anyone who experiences problems with resin odours or is concerned about safety and health while 3D printing. It’s a feature that has made a significant difference in my work experience, and I’m sure it will do the same for you.
