The rear-mounted carbon air filter is a thoughtful addition that ensures filtered air. Despite the filtering of the air, we must stress that it is still generally recommended to keep the resin 3D printing process going in well-ventilated special rooms and follow all safety guidelines meticulously to minimize health risks.

Its exceptional print resolution of 29.6-micron XY resolution delivers prints of outstanding clarity and precision with the use of NFEP, an additional feature that boosts quality and durability. To help users hit the ground running, they included a complete toolkit comprising of hex keys, metal scrappers, silicone scrappers, a funnel, A USB stick, paper filters, gloves, and more.

 

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.

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.
