SLA 3D printing service

How does SLA Plastic 3D printing work?

The principle of SLA rapid prototyping:

The computer-controlled laser beam scans the surface of the raw material point by point, and the resin thin layer (0.1mm) in the scanned area undergoes photopolymerization reaction to solidify, forming a thin layer of the part. Move the workbench down by a thickness of one layer, so that a new layer of liquid resin can be applied to the cured resin surface for the next layer of scanning processing. Repeat this process until the entire prototype is manufactured. 

• The SLA process generally requires cleaning, de supporting, polishing, and re curing to obtain products that meet the requirements.
• The SLA process requires support to be added to the suspended wall area, and the product and support are made of the same material.
• For color models, later color treatment is also required.

Advantages of SLA 3D printing:

The SLA process is very beneficial for those who need to produce high-precision, high surface quality, and multi detail plastic parts for prototype design and simulation, appearance verification, assembly verification, and functional testing as well as for those in low volume production.

(1) High precision, smooth surface, capable of producing large-sized products;

(2) Good rigidity, excellent sharp angles, and small shrinkage;

(3) Excellent surface details, extremely textured, and fast production speed;

(4) There are various types of resins (white, semi transparent, fully transparent, high toughness, etc.) to meet various performance requirements.

What materials can you choose for SLA 3D printing?

Parts Structure Requirements for SLA resin printing:

(1) Min wall thickness: 0.6mm (large area thin thickness should be greater than 2mm);

(2) Min independent column diameter: 1mm;

(3) Min stroke width for convex (concave) characters: 0.35;

(4) Min hole diameter: 1mm;

(5) Minigap: 0.4mm;

Surface treatment for SLA resin printing:

Products without polishing treatment may have layer patterns on the surface, which can be polished off. It is suitable for various surface treatment processes such as polishing, sandblasting, spraying, dyeing, screen printing, and electroplating.
