Collaboration with renowned companies like Henkel Loctite underscores the printer's suitability for industrial applications and provides makers with access to high-quality materials specifically designed for 3D printing.
The print quality of the SL1S SPEED is ensured by its 15.14 cm (5.96'') monochrome LCD with a resolution of 2560×1620p. This high resolution allows for extremely sharp and detailed prints, which is especially advantageous in jewelry making and the dental industry, where precision is critical.
Another innovative feature is the tilting mechanism of the resin tank. After each layer is cured, the entire display tilts with the vat. This not only ensures a smoother release of the model from the FEP film but also allows for continuous resin mixing in the vat, significantly increasing print speed. For makers, this means shorter wait times and increased productivity as the overall printing process is accelerated.
The resin calibration function is another highlight that enables makers to efficiently test different resins and quickly find optimal printing settings. This is particularly useful for maximizing print quality and avoiding material waste, as the ideal settings for each resin can be quickly determined.
A practical feature is the resin sensor, which measures the resin level before each print. It provides indications of whether there is enough resin available or if a refill is needed, and prevents possible overflow through warnings. This ensures a smooth printing process and protects the printer from damage caused by overflowing resin.
Finally, the connectivity of the SL1S SPEED via Wi-Fi or Ethernet offers a range of benefits, including automatic firmware updates and the ability to monitor and control the printer remotely. This means more flexibility and control over your printing projects, as you can access the printer from anywhere. These comprehensive features make the SL1S SPEED a powerful tool for makers who are active in both hobby and professional fields.
Material Compatibility — What Can the Prusa SL1S SPEED Print?
The Original Prusa SL1S SPEED is an MSLA 3D printer that stands out for its ability to produce highly precise prints with impressive speed and detail accuracy. Unlike FDM printers that melt filaments, the SL1S uses the curing of liquid resin through a UV LED array and a monochrome LCD panel. This technology brings some advantages but also specific requirements for the materials used.In terms of material compatibility, the SL1S SPEED is compatible with a variety of photopolymer resins suitable for different applications. The MSLA technology does not require high nozzle temperatures or heated bed temperatures, as is the case with FDM printers. Instead, the critical factor is the wavelength and intensity of the UV light responsible for curing the resin. The SL1S is designed to work with standard 405 nm UV resins, which are widely available and offer a wide range of mechanical properties, from hard and impact-resistant to flexible and rubber-like materials.
This variety of materials allows the printer to be used for a wide range of applications, whether for prototyping, jewelry design, dentistry, or miniatures. A key advantage of MSLA technology is the high detail accuracy achieved through the fine layers formed by the curing of the resin. This is particularly important for applications where precision and fidelity to detail are crucial.
However, there are also limitations: resins can generally be more expensive than filaments, and handling requires caution, as they are liquid and potentially harmful to health before curing. Additionally, it is important to pay close attention to the curing parameters, as not all resins cure optimally under the same conditions. An additional step in the process is post-curing the prints to achieve their final mechanical properties, which often requires a specialized curing unit.
Overall, the Prusa SL1S SPEED offers an excellent platform for resin printing with a wide range of material options, as long as the specific handling and curing requirements are observed.
