SLA Resin 3D Printing

Whether you are a product designer, engineer, or model enthusiast, we can use high-quality and efficient SLA resin 3D printing to help you turn your ideas into reality!

As a rich experience prototype manufacturer, Alec uses advanced industrial-grade SLA 3D printing to provide customers with high-quality resin printing. Our SLA 3D printing has the following advantages:

1. Our SLA 3D printing equipment can achieve an accuracy of ±0.05mm, and the minimum layer thickness can reach 0.025mm, which can accurately present complex structures and tiny details. Whether it is small characters, complex textures or fine parts, they can be printed directly without additional finishing.
2. Our SLA prints have a smoother and more delicate surface, with almost no layer lines, and can be used directly for display or production. The surface roughness is as low as Ra 1-3μm, and it can have a high-end and exquisite appearance without too much polishing. With a little treatment, the transparent resin can also achieve an effect close to optical transparency, which is suitable for products such as optical lenses and transparent shells.
3. SLA 3D printing does not require molds, and can quickly print complex shapes and fine internal structures, such as hollow designs, fluid channels, fine grids, etc. It is particularly suitable for product development and prototype testing, making design verification faster and reducing costs.
4. Our SLA 3D printing can be completed in as fast as 24-48 hours, which is much faster than traditional processing methods. It can also support small-batch production, without molds, direct printing, which is both cost-effective and allows products to be launched faster.

In the product development process, time and precision determine market competitiveness. Alec uses industrial-grade SLA 3D printing technology to provide high-precision, high-efficiency, and customizable manufacturing services for multiple industries, helping engineers and buyers quickly complete prototype verification and functional testing.

1. Consumer electronics industry: Alec provides ultra-high-precision SLA printing (±0.05mm), supports surface treatments such as transparent processing, painting, and electroplating, ensuring that the sample is closer to the final product effect.

SLA 3D printing has become an indispensable prototype manufacturing tool in the consumer electronics industry, helping companies complete design verification, functional testing, and market research in a short period of time. 

• Shell design verification: Applicable to product shells such as mobile phones, smart watches, and smart speakers, helping designers optimize the structure and appearance before formal mass production. 
• Rapid iteration of structural parts: For example, for parts such as headphone components and brackets, SLA printing can quickly produce test samples and optimize assembly effects.
• SLA transparent resin can be used to print transparent optical parts, such as lampshades, light guides and other optical parts, to optimize optical design and make the light effect better.

2. Alec can also provide high-precision SLA printing for the medical device industry, with biocompatible resin, in line with medical industry standards, support customized small batch production, suitable for medical device prototypes and exclusive customized parts.

The medical industry has extremely high requirements for precision and materials. Alec provides SLA 3D printing solutions that meet biocompatibility and medical-grade requirements to help medical device innovation. 

• Surgical guides & dental models: Print accurate surgical guides and dental models to help precision medicine and personalized treatment. l
• Implant appearance verification: Use biocompatible resins to print ergonomic medical device shells for early product testing and doctor verification.

3. Automotive industry: Alec has extensive experience in 3D printing of automotive parts and supports material selection such as high-temperature resins and impact-resistant resins to meet the needs of different environments.

Widely used in the automotive industry for functional testing and appearance verification, helping engineers optimize designs faster and improve development efficiency.

• Instrument panel & handle prototypes: used for design verification to ensure that the final product is both ergonomic and visually appealing.
• Functional test parts: can quickly print functional parts such as air ducts and electronic connectors for assembly testing and performance evaluation.

1. What is the minimum accuracy of SLA 3D printing?

SLA 3D printing accuracy can reach ±0.05mm, layer thickness 25-100μm.

2. Can transparent parts be printed?

Yes, we provide polishable high-transparency SLA resin, suitable for transparent housings, lampshades and other needs.

3. Can SLA resin parts be used for functional testing?

Yes, but it depends on the type of resin. For example: high-toughness resin is suitable for mechanical strength testing.

4. How long does SLA 3D printing take?

Standard delivery time is 24-48 hours, and expedited service can be completed in as fast as 12 hours. It depends on the complexity of the part structure.
