SLA 3D printer, also known as stereolithography 3D printer, or laser 3D printer. SLA is an abbreviation of "Stereo Lithography Apparatus", which is an abbreviated form of stereolithography.

Technical principle:
Focusing on the surface of the photocurable material with a laser of a specific wavelength and intensity, from point to line, from line to surface solidification, complete a level of drawing operation, then move the lifting table vertically in the height of a layer, and then solidify Another level. This layer stacking constitutes a three-dimensional entity. SLA is the first practical rapid prototyping technology, using liquid photosensitive resin raw materials.

Technical advantages

1. The technology is mature. The photocuring molding method is the earliest rapid prototyping process with high maturity and time-testing.
2. Fast speed. The prototype made directly from CAD digital models, processing speed is fast, the product production cycle is short, no cutting tools and molds are needed.
3. Manufacture of complex structures. It can process prototypes and molds with complex structural shapes or difficult to shape using traditional methods.
4. Design changes are easy. Visualize CAD digital models and reduce the cost of bug fixes.
5. The design change cycle is short. Once the design problem is discovered, the design changes can be quickly implemented, samples can be provided for the experiment, and the results of the computer simulation calculation can be verified and verified.

This equipment is compatible with any photopolymer specifically designed for SL processing. Machine parameters can be adjusted to the degree decided by the equipment owner. Platform sizes vary from 300*350*350mm to approximately 1700*800*600mm (model dependent), facilitating the production of larges parts or multiple smaller parts. These freedoms in design create an open path for innovation and collaboration whether you are considering a prototype, indirect or direct manufacturing option.

FAQ

1. What are the main parts of KINGS SLA Printers?
Laser: Optowave (US brand)
Scanner: ScanLab (German brand)
Platform: Full marble structure: marble recoater frame (marble on four sides, in two-square shape), marble elevator holder, and marble scanning system base.
Recoater: High stiffness light recoater to ensure recoating accuracy and efficiency

2. May I ask what software do I need for the machine?
There's two software: one is machine control software, and the other is file preparation software.
Machine control software: We have been developing and innovating our own software since the very beginning, and the experience of the team can date back to the year 2003. The control software is one of the main core competencies, ensuring long term printing stability. Sure this is included in the price. And our team is continuously updating the software, and all future software updating will be free of charge.
File preparation software: Magics is needed for file preparation.

3. What is the major difference between different sizes?
Kings 3D has 12 models with printing sizes ranging from 300*350*350mm to 1700*800*600mm. Start from Kings 1200Pro, two lasers are adopted. The major difference is max printing size, so you can select the model according to your product size.
4. How are the warranty, maintenance, and after-sale issue?
Warranty: 2 years, including laser
Maintenance: Machine maintenance is simple: adding oil for recoater rail once a month, and cleaning the recoater once a week
Aftersale: Unlike some desktop machines, the industrial SLA 3D printer has a very high level of stability. In case there's an issue, if it's software, we have a quick responsive after-sale team, who can solve problems or update software with Team Viewer through remote control. If any replacement in hardware is needed, we'll send it soon by fastest express, and a video illustrating how to replace it. In worst cases, if on-site service is really needed, we'll send engineers from European partners or from China.

5.About working long hours?
The Kings machine can work 24hours a day and 7days a week, with no problem for working long hours. About 40% of the kings' customers are from prototyping companies or printing stores, and from the customer feedback, we know that their machines are working about 90% of the time.
The only thing you need to note is that the workshop should keep at the temperature (20~25sºC) and humidity rate (<40%) as suggested

6. What is the cost of 3d printing compared to CNC machining?
3D Printing has much better cost performance, by cutting greatly on labor cost. Below is labor fee saved compared to CNC (take Chinese salary level for instance):
1)  CNC needs an operator watching the machine, whereas the 3d printer needs no operator. One operator's salary is around 650usd per month, saving 650usd*12=78000usd
2)  CNC programming work needs at least 6-12 months' training and the salary of an experienced worker is 1500usd per month. But file preparation work for SLS 3d printing is very simple, which takes just one-week training. If you use the same workers for the programming worker, you only need half the time, saving half a labor: 750usd*12=9000usd
3)  post-processing is so much simple, saving one worker, maybe 500usd*12=6000usd
Labor cost saved in total per year: 78000+9000usd+6000usd =22800usd

7. Can I buy one machine and use it with two different kinds of resin, by changing resin from the tank? Or do you offer a replaceable tank machine?
A. The machine works well with all kinds of resin, and there's a faucet in the bottom of the tank for easy resin outflow. Therefore, theoretically, we can change resin from the tank to a new one. Yet practically it's not common to do so, mainly for two reasons:
One major reason is that for industrial SLA, with the top-down printing method, a full tank of resin needs to be invested. Take Kings 600Pro for instance, if you plan to print the second kind of resin, you have to invest in another 240kg new resin to fill in the tank first before printing.
The other reason is complicated labor work in changing resin and in cleaning work for the tank, recoater, plate, and etc.
B. As to replaceable tanks, we can offer it on a customization basis. Yet even with a replaceable tank, you will still need to clean the recoater and plate to avoid any contamination, esp. for clear resin. Therefore, the generally replaceable tank is not recommended for practical reasons, since the second tank is rarely used, and we can also help you print models with special resin before you get more regular orders for the new resin.

8. What makes KINGS different from the other SLA 3d printer suppliers?
Kings was established in 2007 as a prototyping company, end-user of 3d printer (called rapid prototyping machine at that time). We found issues with both the domestic and oversea machines as an end-user and we aimed to develop our own machines. By joint effort with a shanghai R&D team who started the R&D of SLA in 2003, we made the first Kings' machine in 2012. Initially, for Kings ourselves, the Kings machine has been very well received as soon as it was launched into the market.

Below are major advantages of Kings:

1. With in-depth and mature research on different applications, we provide customized control software and 12 machine sizes for different industries: prototyping, shoe, automotive, ceramic, and etc.
2. Fast Speed in printing. With the maturing SLA technology inaccuracy, Kings has furthered the R&D of printing speed, and become 20%-50% faster compared with peers.
3. Long term printing stability with large size machine. Kings stands out in peers for big size machine and enjoys the largest market share in big size machines. Kings is not only the first one who developed Kings 800Pro ( 800*800*500mm), but also the first who has developed Kings 1700Pro (max printing size 1700*800*600mm) with two lasers. The big machine is the touch-stone of technology capability.
4. Quick response in the after-sale issue. Kings has enjoyed a fame in being quick- responsive whenever the customer has any questions in using the machines.
5. Short lead time -- about 10 working days.
6. More choices in printing materials: ABS-like, PMMA like, rubber-like, PP like, high-temp resistant resin, and etc. With rich experience in machine using and testing, Kings 3D has developed stable parameters with different kinds of resin.

Application:
Kings 3D printers have been well received by many industries, including prototyping, shoe, automobile, architecture, art&craft, ceramics, medical application, etc. (We are the first 3D printer manufacturer to provide professional solutions for Shoe mould industry.)
