Today I’m looking at a company I had not heard from previously, Kings 3D Printing, who claim to market the largest SLA 3D printer in China.
The company, based in Shenzhen, began its 3D printing operations way back in 2008, then located in Shantou. Volume production of industrial 3D printers commenced in 2012. Since then the company has expanded greatly, now operating production centers in both Shanghai and Shenzhen.

The company now markets no less than eleven different industrial 3D printers. These are all large units with features suitable for factory floors; there are no desktop or even professional 3D printers in Kings 3D Printers’ lineup. None are tabletop devices.
Kings 3D Printing exclusively produces SLA-style 3D printers that use lasers to selectively cure liquid photopolymer resin, which are available in a variety of build volumes.
Kings 3035 Pro
The smallest volume SLA 3D printer in their lineup is the Kings 3035 Pro, which has a build volume of “only” 300 x 350 x 350 mm. The device can produce layers as small as 0.05mm with a laser spot diameter of 0.1mm, suggesting that the device can produce objects with high resolution.
355nm Laser
Curiously, the Kings 3035 and indeed all the other machines from Kings 3D Printers use a laser with a wavelength of 355nm, which is a bit different than the industry de facto standard of 405nm. This means you would have to be a bit more careful when selecting resin for use in the machine, as some resins on the market are designed for use specifically with 405nm lasers.
Kings 1700 Pro 3D Printer
But what I really want to talk about is the large machines from Kings 3D Printers. In fact, there are two models that have an identical and extremely large build volume of 1700 x 800 x 600 mm. These would be the Kings J-1700-H and the Kings 1700 Pro.
The machines present identical specifications, but the J-1700-H is targeted at automotive companies to produce large components in a single print job.
The massive 2400kg machines use lasers that appear identical to those used in the smallest machine, as they have the same specifications: 0.05mm layer size and 0.1mm laser spot diameter. Both machines heat from the bottom of the silicone-coated resin tank.
The differentiating feature is, of course, the huge build volume. For this, the Kings 1700 Pro includes a resin tank that can accomodate a whopping 1300kg of liquid photopolymer. Clearly this device can 3D print very large objects, but I suspect the print durations might be fairly lengthy.
How large an item can you 3D print? This image of a sample print from the Kings 1700 Pro tells all:
