Kings SLA600 prints 600×600×400 mm resin parts fast, stable under UAE heat.
Short intro, no theatrics. 600 millimeters in X and Y, that is the headline. Shops in Sharjah that try to cast poly-urethane patterns, they look at the envelope first, not the logo. I have seen guys cram a bumper prototype in the vat, wipe sweat off the forehead, nod, good, it fits.
Kings has been building stereolithography rigs for about 12 years, roughly 3 000 units shipped worldwide, half of them in the last five because resin got cheaper. The SLA600 sits right in the middle of their line, not the biggest, definitely not the toy size. They released revision 4 last year with a stiffer granite bridge, that is the one we talk about.
Now, before I dive into numbers, a quick list of situations where the machine pays for itself faster than a coffee machine in the office.
Text first. Then the list.
Three lines, you get the picture. Everyone in the Gulf keeps talking about heat, so, yes, the chiller block inside the laser module is rated for ambient 45 °C, Kings publishes that in the datasheet.
The heart is a 355 nm diode-pumped laser, 3 W nominal. Galvos swing up to 10 meters per second, but real life jobs stay around 5 to hold surface finish. The vat is welded stainless, 250 litres, temperature held at 28 degrees by a dual loop. That is one of those small details, you set it once and forget.
Before moving on let me throw a markdown table, people love tables, I will too.
| Parameter | Kings SLA600 | Formlabs Form 3L | UnionTech RSPro 600 |
|---|---|---|---|
| Build volume | 600×600×400 mm | 335×200×300 mm | 600×600×500 mm |
| Laser power | 3 W | 2×250 mW | 3 W |
| Footprint | 1.5×1.4×2.0 m | 0.9×0.8×0.9 m | 2.2×1.9×2.3 m |
| Net weight | 1 800 kg | 54 kg | 2 500 kg |
| Stated accuracy | ±0.05 mm/100 mm | ±0.1 mm/100 mm | ±0.07 mm/100 mm |
So, bigger than the hobby Form 3L, a hair shorter in Z than RSPro yet easier to squeeze through a doorway. After the table I breathe, you breathe, we continue.
Typical shift, 9 am. Operator clicks Job 123 on the touch panel. STL comes in over Ethernet, not USB, nobody likes dangling sticks. Pre-heat resin to 28 °C, system does it in about 15 minutes, faster than loading powder into an SLS booth. The air in Ajman gets dusty, so Kings throws in a HEPA filter stage, nothing fancy, does the job, swap every 500 hours.
Another bullet list? Sure, but only after I talk a bit more. The following extras show up in most quotes I have seen for clients from Dubai Industrial City.
Notice how the list sits snug between lines of prose. Good.
Kings labels printers by X dimension. SLA500, SLA600, SLA800. Same controller board, same GUI, just rails get longer. SLA500 tops at 500×500×400 mm, prints a tad faster because the galvanometer covers less angle, about 12 percent throughput gain. SLA800 goes up to 800×800×550 mm, but you need a forklift and a doorway wider than 2.5 m, that alone knocks it off the plan for many urban workshops.
I hung out on a Telegram chat of Gulf service bureaus, grabbed two quotes, kept them anonymous.
“Surface comes out at 60 micron average Ra on grey resin, we skip primer for show models.”
“Chiller alarmed once at 44 °C ambient, quick nozzle clean, never repeated.”
They are not marketing slides, just chat logs, yet they say more than brochures.
Every machine lives or dies by upkeep. Filters every 500 hours, vat liner swap every 2 000 hours, laser realignment check every 1 000 hours, took our tech 40 minutes last time, two hex keys, a feeler gauge, done. Spare parts ship from Shenzhen to DXB in 5–6 days air freight, customs clearance adds another 2.
Total draw peaks at 2.5 kW during resin heating, settles at 1.6 kW under steady run. With DEWA tariffs that is small change. Cooling loop dumps into a closed glycol unit, 3.2 L/min flow, no external chill water needed.
UV shutter rated 1 million cycles. Door interlock IEC 60204 compliant. Resin fumes pulled through an activated carbon cassette, change yearly if you run one shift, twice if you never shut down, your nose will tell.
Simple payback table, numbers rounded, you do your own spreadsheet later.
| Metric | Value |
|---|---|
| Average part volume | 4 000 cm³ |
| Parts per build | 5 |
| Builds per week | 4 |
| Resin cost per kg | 90 USD |
| Annual gross margin | ~75 000 USD |
I keep it short, accountants can fight over decimals.
Not a fairy tale, just blunt facts.
I would be dishonest if I skipped drawbacks. Shutter motor is proprietary, local rewinds cannot help if it dies, order a spare. Touchscreen is resistive, not pretty, but gloves slide better on it. Software UI is plain, Windows 98 vibe, though post processing works.
The SLA600 is a work mule. Nothing flashy, no RGB lights, just a big tank of liquid photopolymer and a beam that does laps all day. Enterprises in UAE that cast aluminium impellers, build composite molds, or supply luxury interior parts, they gravitate to volume, reliability, and the fact that Kings keeps BOM common across models so spares stay cheap.
If you need bigger, go SLA800. Need smaller, the 500 does fine, just watch the Y envelope. As always, run a sample file before buying, measure warpage at 35 degree ambient, that is the real test.
Enough said, you already know whether the printer fits your plan.
