The majority of curious users of 3D printing begin with Fused Deposition Modeling machines. FDM printers are affordable, simple to operate, and have a sizable and active user and expert community. Additionally, there is so much to learn about FDM printing that it may take years for you to master it.
Fundamentals of SLA printing
SLA uses photopolymer resin as its raw material as opposed to the filaments used in FDM printing. When exposed to UV light, this liquid solution virtually instantaneously solidifies. When compared to filament-based printing, this method is far faster and produces prints that are more intricately detailed. On the other hand, resin printing is a bit more costly and untidy.
Despite being a more established 3D printing process than FDM, SLA hasn’t yet attained the same degree of widespread acceptance. It’s not particularly user-friendly for beginners, and SLA printers were formerly mostly employed in industrial and commercial environments.
Considerations for design
Not all types of 3D printing models or projects are suitable for SLA. Without a doubt, SLA printing has advantages when done correctly, but this does not imply that it is always the best choice. Be aware of the limitations of SLA before switching.
An SLA printer would probably have a significantly lower build size than an FDM printer with a same footprint. SLA printers’ function in a similar manner; in addition to a build plate, they also include a containment vat for liquid resin.
SLA printers are generally utilized for tiny tasks like miniatures because of this. There are SLA printers that can produce greater build sizes, so yes. But they are pricey and often exclusively used in industrial environments.
Appropriate for specifics
Resolution is one of SLA printing’s strong points. The size of the UV laser limits the resolution of SLA printing rather than a nozzle. Because it is much smaller, this is ideal for intricate work. Due to its astounding accuracy, SLA printing has become a favorite in the small manufacturing business.
Limited options for resin
There are some top resin 3d printer is available. SLA printing is progressively gaining popularity, although it’s still not as common as FDM printing. FDM printer users have a wide range of options. You may get filaments that glow in the dark, mimic the look of wood, ceramics, or other metals, in addition to a variety of other hues.
There are fewer possibilities available for resins. In actuality, most resins used in 3D printing are either black or gray. If you intend to paint your SLA prints, this isn’t too much of an issue.
Poorly performing bridging and overhang
In additive manufacturing, bridges and overhang features are often troublesome. Due to the 45-degree overhang restriction, there is some tolerance in the case of FDM. SLA prints perform less admirably. Many people even claim that SLA printers have almost no tolerance for overhangs and bridging.
This can only indicate one thing: you will need to print with plenty of supports if your model has a lot of overhanging parts. This increases the already strenuous post-processing phase’s workload.
