SLA, standing for Stereolithography Apparatus, represents the earliest and most precise industrial-grade 3D printing technology. Its operational principle involves:
--Utilizing ultraviolet laser (typically 355nm wavelength) to perform --micron-level scanning on photopolymer resin surfaces
--Layer-by-layer curing of liquid resin following digital model contours
--Cumulative material solidification to form complete 3D parts
Moreover, spray painting surface finishing can achieve any color and gloss level (matte/metallic/high gloss), and techniques such as shading and dry brushing can enhance the layering of details, transforming the model from a "plastic product" into a work with a sense of life.

01
Wide material compatibility and strong application adaptability
It can be applied to various 3D printing substrates such as ABS, resin, and metal, with customized spray painting solutions tailored to the characteristics of different materials-for example, applying high-adhesion primers for resin substrates and adding anti-corrosion coatings for metal substrates. Additionally, it offers a variety of finish effects, including matte, glossy, sandblasted, metallic, fluorescent, and luminescent options, meeting diverse needs for material appearance and performance across different scenarios. This approach breaks through the limitations of traditional spray painting on substrate materials.
02
The model excels at flexible small-batch customization and efficient delivery
Unlike traditional manufacturing, which involves lengthy mold development cycles and high-volume production thresholds, our customized services require no molds and support orders starting from a single unit. From design confirmation to finished product delivery, we offer expedited turnaround times as short as 48 hours. For small-batch and multi-batch customization needs, our digital production management system optimizes workflows, ensuring seamless coordination between printing, painting, and quality inspection. This approach not only reduces costs for small-batch orders but also ensures timely delivery, enabling personalized demands to be realized quickly.
03
Superior environmental performance and reliable, safe quality
The entire process utilizes water-based coatings and low-VOC solvent-based coatings that comply with national environmental standards, reducing pollutant emissions at the source and ensuring a safe production environment and final product quality. All coatings have passed authoritative certifications such as SGS and ROHS, offering excellent properties including scratch resistance, tolerance to high and low temperatures, aging resistance, and waterproofing. The finished products are suitable for use in various indoor and outdoor environments. For instance, outdoor cultural and creative products maintain vibrant colors even after prolonged exposure to sunlight and rain, while industrial components retain coating stability under complex working conditions-effectively balancing environmental sustainability and durability.
04
Whole process
Our industrial-grade SLA manufacturing process ensures precision and quality at every stage:
Step 1: Needs Communication and Design Optimization
Our professional team engages in in-depth discussions with clients to understand customization requirements, covering product usage, material selection, aesthetic effects, dimensional accuracy, delivery timelines, and more. For design files (such as STL, STEP, etc.) provided by clients, we conduct optimization reviews to identify potential printing defects, painting blind spots, and other issues. We also propose reasonable structural adjustment recommendations to ensure that the design aligns creativity with manufacturability.
Step 2: 3D Printing Production
Based on the optimized design files, appropriate base materials and printing processes (e.g., SLA, SLS) are selected, and industrial-grade high-precision 3D printing equipment is utilized to initiate production. Throughout the printing process, the equipment's operational status is monitored in real time to ensure printing accuracy and structural integrity. Upon completion, preliminary support removal and surface polishing are performed to prepare the printed objects for subsequent painting processes.
Step 3: Surface Pre-treatment Process
Refined pre-treatment is applied to the printed products, including secondary polishing (to remove surface burrs and defects), dust removal and cleaning (to eliminate surface dust and oil stains), and primer spraying (to enhance topcoat adhesion and fill minor imperfections). Specialized pre-treatments are implemented based on material types-such as derusting for metal materials and curing for resin materials-ensuring seamless bonding between the coating and the substrate.
Step 4: Customized Painting Phase
A painting plan is formulated based on client requirements, selecting corresponding coatings and painting techniques.
Step 5: Post-Treatment and Curing
After painting, the surface undergoes leveling to ensure a smooth and uniform paint film, followed by curing in professional equipment using methods such as UV curing or high-temperature curing, depending on the coating characteristics. Once cured, secondary polishing and finishing processes are applied to enhance the texture and quality of the painted surface. For products requiring special functional properties, additional protective coatings-such as wear-resistant or waterproof coatings-are applied to meet specific performance needs.
Step 6: Quality Control & Shipping
The final products must undergo quality inspections such as size and appearance, and only after being confirmed to be free of defects can they be packaged and shipped.
