SLA vs SLS
When you’re getting ready to get your design made into a prototype, choosing your method is an extremely important step in the process.
If you’re reading this article, you’ve probably already settled on 3D printing…or you’re at least leaning in that direction. Two of the 3D printing services we offer are SLA and SLS.
Before we talk about the advantages or disadvantages of each, let’s talk a little bit about what each process is and how it works.
SLA, or stereolithography, is the most common type of 3D printing. It was invented in 1986 by Chuck Hull, making it the oldest of the 3D printing methods.
Items printed in this way are created by shining an ultraviolet beam of light into a vat of liquid photopolymer (plastic resin that can be hardened by UV rays). Each time a layer is cured, the object is lowered slightly so that the next level can be built.
Creating a 3D print this way means that it needs a supporting structure, which is usually automatically generated within the 3D printer’s CAD software.
SLA can be pretty detailed, but usually doesn’t create functional parts. And since the plastic hardens under UV rays, objects that are printed using this method can’t be left out in the sun—they’ll become brittle and finally break.
SLS, our other option, is an acronym for selective laser sintering. This method, as you can probably guess, uses a laser to sinter (heat until it solidifies) powdered material.
This process was developed in the late 1980s by a pair of researchers at the University of Texas at Austin in a project sponsored by DARPA.
Although SLS creates a much stronger item than SLA and can be used to make functional prototypes, it won’t be very pretty. SLS has a rough surface finish that doesn’t make it aesthetically pleasing.
So if you want to decide between SLS vs SLA, here are a few key differences:
|– smooth looking finish||– rough finish|
|– not very durable, will crick over time if exposed to sunlight||– not for display prototypes|
|– great for display items, not for functional models||– very durable, good for testing the functionality of the design|
|– slightly cheaper than SLS||– if you think SLS might be the right 3D printing method for you, consider CNC machining—it will give your prototype a much nicer finish.|
What can we do?
We take the CNC machining as core technology, meanwhile, we integrate other upstream and downstream resources in our industrial chain to provide service for the customer.
We have 4 five-axis CNC, more than 30 high-speed CNC machining centers, CNC lathes, CNC carved machines, in total we have more than 50 machining equipment.
We are able to provide machining service of CNC milling, turning, engraving, cutting, tapping, drilling, etc.
Quality control & After-sale service
We will provide all documents as you need such as inspection report, material report, etc. To meet your quality requirements of products and parts.
If the parts have any quality problems when you got them, no matter it happened when we made them or caused by the delivery, we will try best to help you to solve the problems and take our part of responsibility, so you will be free from worries.
