Performance optimization: SLA in low-volume production

Technology Applied, the largest company offering 3D printing services in Poland, bases its activities largely on the selective laser sintering (SLS) technology, but for some time now it has been developing the stereolithography (SLA) technology in parallel thanks to the DWS Systems XPR S large-format 3D printer. The machine expands the scope services, and increases the possibilities of optimizing efficiency in the production of low-volume parts.

SLA – a 3D printing method that uses UV light to harden light-cured resins layer by layer, is known for its ability to create complex and highly detailed objects with excellent surface quality. Importantly, DWS Systems XPR S is distinguished by its working area, which is large enough to enable the production of larger parts or more small parts in one production process. This second thing is crucial in the production of large series of parts.

The main advantages of SLA in low-volume production are:

• High precision and quality of details: SLA enables the creation of products with an exceptionally high degree of detail and surface smoothness, which is irreplaceable in high-quality serial production.
• Increased efficiency: The DWS Systems XPR S working area of 30 x 30 cm in the XY axes allows for the simultaneous production of many parts, which significantly speeds up the production process.
• Material diversity: SLA allows the use of various resins, which allows the physical properties of products to be adjusted to specific requirements.

Types of applications that can be performed using SLA technology in additive manufacturing:

• Medical components: production of precision medical instruments and devices that require high accuracy and biocompatibility.
• Automotive and aerospace parts: complex components requiring high precision and durability.
• Architectural prototypes and models: SLA is ideal for creating detailed architectural models and prototypes characterized by high accuracy and transparency (e.g. elements imitating glass).
• Jewelry and luxury items: 3D printing using SLA technology enables the production of complex patterns and delicate details in jewelry.
• Electronics: SLA makes it possible to create housings and electronic components with a high degree of complexity.

Technology Applied’s integration of SLA technology is an excellent step in expanding its manufacturing offering, enabling the production of parts that would be difficult or impossible to produce using powder technologies. The use of SLA in series production opens up new opportunities for the company in terms of efficiency, precision and diversity of applications. DWS Systems XPR S with its large work area allows the company to implement larger projects and meet the specific needs of customers in various industries, from medicine to automotive.
