Creating with SLA 3D Printing

Stereolithography (SLA), commonly referred to as resin 3D printing, is a cutting-edge technology that excels in producing parts with exceptional resolution, precision, intricate details, and smooth surface finishes. As a form of vat photopolymerization printing, SLA utilizes photosensitive thermoset polymers to fabricate custom parts. Our facility leverages stable materials for rapid prototyping needs and utilizes 3D Systems qualified materials for large-scale production projects.

ARapidPrototype Providing High Quality Service for SLA 3D Printing

 
At ARapidPrototype facility, we meticulously craft your bespoke components adhering to rigorous manufacturing standards, ensuring strict compliance with The ARapidprotoype Network Standard. 
 
  • Each order undergoes a comprehensive verification process, detailed in our inspection report included with every shipment.
  • Prior to delivery, parts are fully cured according to material manufacturer specifications. 
  • Additionally, hollow sections are carefully drained of excess resin, and all support material is expertly removed with support nibs meticulously sanded smooth.

SLA Post-Processing Options

  • After printing, careful removal of supports is essential to prevent any damage to the parts during the initial processing phase.
  • Subsequent dimensional checks and assembly verifications are conducted before proceeding with any surface treatments. This ensures that the parts meet the exact engineering requirements of the client.
  • Using varying grades of sandpaper for polishing allows for customization based on specific client preferences, achieving different levels of surface smoothness. This is particularly crucial for parts requiring additional surface treatments such as painting, UV curing, or electroplating.

 Advantages

  • SLA can produce parts with very high dimensional accuracy and intricate details.
  • SLA parts have a very smooth surface finish, making them ideal for visual prototypes.
  • Speciality SLA materials are available, such as clear, flexible and castable resins.

 Drawbacks

  • SLA parts are generally brittle and not suitable for functional prototypes, though industrial SLA can produce more functional components for this stage. 
  • The mechanical properties and visual appearance of SLA parts will degrade over time when the parts are exposed to sunlight.
  • Support structures are always required and post-processing is necessary to remove the visual marks left on the SLA part.

What is Stereolithography?

Stereolithography (SLA) is a powerful 3D Printing method that produces extremely accurate and high-resolution SLA 3D printed parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping. The processing steps mainly include:
 
  • Design Preparation: Create or prepare a 3D CAD model, ensuring the design file meets printing requirements.
  • Material Preparation: Select and ensure the quality of the photopolymer resin.
  • Pre-Printing Setup: Prepare the printing platform and area, set printing parameters, and pour the resin into the printer’s vat.
  • Slicing: Convert the 3D model into G-code using slicing software, which controls the printer’s path and settings.
  • Printing Process: Use UV laser or DLP light source to cure the resin layer by layer, creating the solid part.
  • Cooling and Solidification: Allow the part to further cure and cool after printing.
  • Cleaning and Support Removal: Remove support structures and clean the part with a solvent to remove uncured resin.
  • Post-Processing and Surface Treatment: Perform necessary post-processing, such as sanding, polishing, or coating.

SLA 3D Printing Service FAQs

Stereolithography, also known as SLA, is a 3D printing technology that uses a laser to solidify liquid resin into precise and complex 3D objects layer by layer.

In stereolithography, a liquid resin is placed in a vat, and a laser selectively exposes the resin to solidify it. The laser traces the cross-section of the object on the surface of the resin, and the solidified layer is then lowered, allowing the next layer to be formed on top of it. This process is repeated until the entire object is printed.

Stereolithography offers several advantages, including high accuracy, excellent surface finish, and the ability to produce intricate and complex geometries. It is particularly suitable for creating prototypes, models, and small-scale production parts.

SLA 3D printed parts have a wide range of applications across industries. They are commonly used for product prototyping, design validation, functional testing, architectural models, jewelry design, and customized medical devices.

 

Stereolithography supports a variety of materials, including standard resins, engineering resins, and biocompatible resins. These materials offer different characteristics such as flexibility, strength, transparency, and heat resistance, allowing for a diverse range of applications.
