The pros of SLA 3D printing

There are many reasons to consider stereolithography, including these:

  • Detail: Stereolithography technology produces crisp, highly detailed results with a professional appearance due to the advanced performance of galvanometers
  • Speed: Products go from drawing board to manufacture in a day rather than much longer using traditional prototyping and production methods
  • Strength: The photopolymer resins bond chemically to produce stronger models, objects, and prototypes
  • Water-resistance: The objects produced are waterproof and can be used to produce water-tight pieces
  • Material options: A variety of resins can be used to manufacture to create objects with the physical properties of hardness, density, and flexibility that are desired for each project

Available Finishes for SLA Parts

Matte (Standard) Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper, then media blasted for a uniform matte finish.
Natural Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.
Strip and Ship Supported areas may show small grid-like dots or surface blemishes as a result of support removal.
Quick Clear Available for Accura ClearVue. Only supported surfaces are sanded. Parts will still have visible layering. High gloss clear coat is applied to enhance natural clarity.
Custom Elimold provides additional SLA finishing options, including but not limited to sanding, polishing, painting, post thermal processing, and plating to meet your needs.

Benefits Of SLA With Elimold

Our SLA services allow you to make 3D printed parts and prototypes in a wide range of plastics. Prototypes made using this service can be used for engineering testing or as master patterns for urethane casting molds. SLA allows the product designer to quickly create complex shapes that cannot be made with conventional subtractive methods. You can also have metal 3D printed parts made using our DMLS 3D printing service.

Why SLA 3d printing?

Smooth surface finish. Easy to paint or metal plate.
Ability to print complex and high-detailed parts.
No visible layer lines unlike FDM prints.
Large scale 3d printing is possible.
Material versatility. Different materials, different purposes.
High accuracy and precision.

SLA 3D Printing Technology Overview

Stereolithography (SLA) technology was the world’s first 3D printing technology, allowing engineers and designers to produce highly detailed prototypes that require tight tolerances and smooth surfaces. Today, SLA remains a great option for printing parts that will ultimately be painted or coated.

Designers usually use SLA-printed models when a quick built time is crucial to the product development cycle as time and resources can be invested into post-processing and finishing techniques. Great applications for SLA-printed parts include concept models, master patterns, large prototypes and investment casting patterns.

How it works - An overview of the SLA 3D printing process

Stereolithography (SLA) is an epoxy-based photopolymer system that utilizes lasers to cure the resin on the cross-sectional area of the part. It begins with a recoating bar that applies a thin layer of resin, then an ultraviolet laser creates an image of the part on that resin. After one layer, this process is repeated until the build is complete.

Once the build is complete, the parts are removed and put into a solvent to remove excess resin. The SLA process uses supports of the same material as the part itself, which have to be manually removed. From there, the parts go through a curing cycle in a UV curing machine.

Uses for SLA 3D Printing

As pricing comes down for the machines, the cost of each object printed falls as well. Here is how stereolithography is being used.

  • Prototyping: Also known as rapid prototyping, creating prototypes was the original purpose of this process. Manufacturing prototypes of parts in a wide range of fields continues to be a popular use for stereolithography. The advantage of this process is that the prototype can be made at far less expense than by using more traditional means. The prototypes are accurate and detailed, even when non-conventional shaping is required. They can be machined and used in the design of master patterns for injection molding, metal casting and thermoforming, among other production methods. The prototypes can then be used to assess the performance of the design, and they are often used in marketing campaigns for the object once production has begun.
  • Medical and dental modeling and prosthetic production: Accurate 3D models of anatomical parts such as bone structures and organs are created with this technology. The models are used in training. They can also be customized for individual patients using the data gained from testing such as an MRI or three-dimensional CT scan. Medical and dental models aid in planning for operative procedures and in the manufacturing of implants and prosthetics.
  • Manufacturing: While SLA 3D printing is not a cost-effective means of mass production, it is an inexpensive way to create one or a few customized products that are unique. For example, designs are used in branding, logo creation, publicity and custom gift making.
