Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries in as fast as 1 day. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.
What is SLA printing good for?
Stereolithography (SLA) 3D printing is the most common resin 3D printing process that has become vastly popular for its ability to produce high-accuracy, isotropic, and watertight prototypes and end-use parts in a range of advanced materials with fine features and smooth surface finish.
Should I get SLA or FDM?
Both FDM and SLA are mature, well-understood 3D printing methods with a variety of use cases. While FDM can be cheaper and easier to get started with, SLA printers have higher print quality and are the only choice for certain projects.
Is SLA easier than FDM?
In SLA printers, it can be difficult to remove the printed model from the print platform. Often, there is a lot of leftover resin left on the platform that you have to clean off and remove as well – this takes more effort than on an FDM printer.
What can you do with a resin printer?
The process allows for very fine detail to be achieved, which makes resin-based printing the go-to technology for figurines and miniatures. The majority of 3D models available online can be 3D printed by both FDM and resin printers, but resin can be superior when it comes to surface quality.
How strong is SLA?
Parts printed in tough resin have tensile strength (55.7 MPa) and modulus of elasticity (2.7 GPa) comparable to ABS. This material will produce sturdy, shatter-resistant parts and functional prototypes, such as enclosure with snap-fit joints, or rugged prototypes.
Are resin prints stronger than FDM?
FDM prints are generally stronger than 3D resin prints. Specifically, the tensile strength of FDM prints ranges from 38-64MPa, while those of resins are generally lower at 23-55Mpa. Also, FDM prints have higher flexural strengths at 2.1-7.6GPa, while resins only average at 60.6MPa.
What temperature can resin prints withstand?
Resin prints can’t melt since they are not thermoplastics. When they get heated to very high temperatures like 180°C, they will scorch and deteriorate. After resin prints have cured they cannot go back to their original liquid state. Resin prints start to soften or lose elasticity at temperatures between 40-70°C.
How can resin improve print quality?
A good rule of thumb to follow is to set the Bottom Layer Exposure Time to be 8-12 times longer than the Normal Layer Exposure Time. This is a good general rule but make sure to keep the bottom exposure time lower than ~30 seconds. Any higher and the printer will get too hot.
How fast is SLA printing?
DLP/SLA 3D printers support even faster 3D printing speeds than FDM printers. While FDM printers often max out at around 500 mm/hr, DLP/SLA printers can achieve speeds of up to 700 mm/hr.
What is the strongest filament for 3D printing?
Polycarbonate. According to multiple manufacturers and reviewers, polycarbonate (PC) is considered the strongest consumer filament out there. PC can yield extremely high-strength parts when printed correctly with an all-metal hot end and an enclosure.
Is SLA better than PLA?
PLA 3D printing is the most popular because it is the least expensive and most widely available. Polylactic acid has some advantages over SLA, but not in performance. If you’re just making your very first prototype or physical model of your project, PLA will work for that purpose.
Can you resin print nylon?

What is the toughest resin?
Liqcreate Strong-X. Liqcreate’s Strong-X is perhaps the toughest resin on this list. Boasting a 91 MPa tensile strength and 135 Mpa flexural strength, it can easily be applied for heavy-duty uses. Strong-X also provides a high-temperature resistance, enough even for injection molding applications.
What are the 3 types of 3D printing?
There are several types of 3D printing, which include: Stereolithography (SLA) Selective Laser Sintering (SLS) Fused Deposition Modeling (FDM)
How do you smooth 3d printed plastic?
Another way to achieve a smooth surface on a print is by adding an additional coating of material, whether sprayed, painted, or dipped. This can fill any defects in the surface texture, including layer lines, and leave a shiny, even finish. Two common examples for PLA are using a paint primer or an epoxy coating.
Where is SLA printing used?
Stereolithography is good for producing accurate prototypes and models. Stereolithography is well used for creating accurate 3D models of anatomical regions of a patient, used to aid in diagnosis and for pre-planning and implant design and manufacture. It is also good for use in concept models and scale models.
Do resin 3D printers smell?
One of the downsides many people experience with resin 3D-printing, is the bad odor of some of the resins and cleaning agents. In order to avoid this smell in their working area, many people get creative and build their own fume hood, just like the picture below.
How long do resin 3D prints take?
Larger models that take up most of the build volume of an SLA printer (around a 15 cm cube) take only around nine hours to print with Draft Resin. Printing the same part at 200-micron layers on an FDM printer can take 80-90 hours.
How does SLA 3D printing work?
It works by using a high-powered laser to harden liquid resin that is contained in a reservoir to create the desired 3D shape. In a nutshell, this process converts photosensitive liquid into 3D solid plastics in a layer-by-layer fashion using a low-power laser and photopolymerization.
What can I do with a 3D printer at home?

What are the advantages and disadvantages of stereolithography?
What are the advantages and disadvantages of stereolithography? Advantages:- Less material waste, Part with high precision as well as smooth finish can be produced. Disadvantages:- The Process requires more time, High initial investment.
What can stereolithography make?
Stereolithography is a 3D Printing process which uses a computer-controlled moving laser beam, pre-programmed using CAM/CAD software. Stereolithography (SL) is an industrial 3D printing process used to create concept models, cosmetic – rapid prototypes, and complex parts with intricate geometries in as fast as 1 day.
What is laser SLA?
Laser based SLA 3D printing uses a laser to trace out the cross-sections of the model. Similar to fused deposition modeling (FDM) 3D printing, where each layer is deposited in a continuous stream of filament, the laser essentially “draws” the layer to be cured.
What do I need to know about 3D resin printing?
Resin printers create 3D objects by curing liquid resin layer by layer. The build plate is dipped into a resin tray, creating the object upside down. After a given layer is cured, the build plate is raised slightly for the next object layer to begin curing.
What 3D printer uses resin?
Like SLA, DLP 3D printers use liquid plastic resin, but instead of a UV-laser beam, the resin is melted with arc lamps. This light source causes the impressive printing speeds because the amount of light allows the resin to quickly harden.
Which is better SLA or DLP?
Curing: Since the curing (hardening) of the resin is done from point to point, SLA 3D printing is more accurate and the quality of the print is also better in comparison to DLP 3D printing.
Which type of 3D printing is best?
Resin 3D printing a great option for highly detailed prototypes requiring tight tolerances and smooth surfaces, such as molds, patterns, and functional parts. SLA 3D printers are widely used in a range of industries from engineering and product design to manufacturing, dentistry, jewelry, model making, and education.
Is resin printing faster than filament?
A resin print (left) compared to a filament print (right). Resin printers are superior at capturing small details and producing a very smooth surface finish without visible layer lines, but make sure to consider all of the factors when making a decision on which technology you prefer.
Are resin 3d prints watertight?
Since the SLA lines are fully bonded to their neighbors, there are also no voids or microscopic cracks typical in FDM prints; these prints are watertight and fully dense.
Is 3D resin waterproof?
Although 3D printed parts have many benefits, they’re not often waterproof. Many people have misconceptions about what “waterproof” means, so let’s clear that up right away. There’s waterproof, and there’s watertight, and they’re very different.
