Orange 30

Longer3D’s first new printer, the Orange 30, is the most cost-effective professional-grade resin 3D printer in the Longer3D Orange range (which includes the Orange10/120/200/300). This resin printer is also a successfully crowd-funded Kickstarter project, and all orders have been fulfilled and shipped.

Longer3D previously released an entry-level SLA 3D printer Orange 10. With good print quality and competitive pricing, it has attracted many users who would convert from FDM to SLA printing. Compared to Orange 10, which has a build size of 98x55x140mm, Orange 30 has a larger print size of 120x68x170, making it slightly larger than most other SLA printers on the market. The Orange 30 has a resolution of 2560×1440 and 47.25 microns. From many of the models it prints, the details are incredibly clear enabling it to meet professional enthusiasts’ strict printing needs. Especially for very small models, high-resolution detail is a must. Although FDM has advantages in printing large objects, it can not meet the requirements of printing fine details. 

It is worth highlighting that all Orange series products use arrayed UV LEDs to provide a uniform surface source. Orange series printers use higher power, up to 72W, for faster printing. The Orange series of products all have a high-temperature warning function. When the LED temperature is high, the printing process will automatically pause and automatically resume printing after sufficient cooling.

Another useful feature of the Orange 30 is the intelligent one-click add support that automatically detects the floating portion of the print and adds mesh support to ensure the success rate of complex model printing.

See here, an example model printed by Orange 30:

The Orange 30 builds on the light source design technology of the Orange series. It has also been upgraded on spare parts. Now all Orange series printers use a powerful silent fan and improve the user experience of the software, such as adding the pop-up for the file saving, instead of being saved in the folder corresponding to the model by default. Another update is the Orange 30 is compatible with Chitubox, which allows for hollowing, making holes and other functions to save resin. The Orange 30 comes with a 250g bottle of resin and also offers many accessories such as gloves, plastic scraper and paper funnel with filter, and spare FEP film.

Overall, orange 30 has the following outstanding points:

1. Excellent print quality, affordable price, retail price is 339 US dollars.

2. Stable print quality, powerful slicing software.

3. Hardware configuration is high-end and ultra-quiet fan.

4. Simple operation.

LK4 Pro

Longer’s other new printer, the LK4 Pro, is the company’s first open source FDM printer, which was upgraded from the original LK4. The LK4 Pro uses the TMC2208 driver and a 4.3-inch display, making it an irresistible advantage. The 4.3-inch display is undoubtedly useful for many people, especially those with clumsy fingers, it allows you to see what you’re doing clearly. The glass building platform is an upgrade of its previous machine LK4, and once the cooling process is complete, the model can be removed more easily.

And its price is very affordable, only $245!

The main features of LK4 PRO:

1 .The latest open source Marlin firmware, expand more functions independently, e.g. automatic bed leveling.

2. Plug and Play TMC2208 driver with higher subdivision, higher running accuracy, and it is ultra-quiet.

3. 4.3 inch touch screen and new UI design engenders ease of use and intuitive response that is unparalleled

4.Glass build platform has better flatness, and the PC sticker ensures a decent print bed adhesion and the model does not warp
