Fdm Vs Sla: The Differences Between Filament And Resin 3d Printers

Should you choose a filament or resin 3D printer? Which one is best for your project?

Few questions are as prominent as the one we seek to answer today. For many years, DIY-lovers, tech enthusiasts, and other creative people have strived to pick the perfect 3D printer for their projects. But how can you choose the right make and model for you if you don’t know the differences between the printing technologies they use?

Join us as we explore two of the most popular 3D printing methods on the market, fused deposition modeling and stereolithography , to provide you with the insight you need into this exciting hobby.

Stereolithography Vs Digital Light Processing 3d Printing

Stereolithography and Digital Light Processing, or DLP for short, are two popular resin-based 3D printing technologies. While they share similar characteristics, the main difference between the two lies in the light sources used for curing the resin.

The stereolithography process works by curing the liquid resin with an ultraviolet laser. DLP stereolithography instead uses a DLP projector to create stereolithography objects.

Sla Vs Fdm: Materials Material Costs And Colours

When we compare FDM vs SLA 3D printing we also have to take into account the materials and especially the costs. FDM technology is the most popular method and therefore many different materials have been developed for it. FDM printers can print on a variety of materials, including the most popular ones: ABS, PETG and PLA. Other filaments such as nylon, TPU and PVA, TPU, PEEK, Ultem and mixtures of wood, ceramics, metal, carbon or fibres can also be processed. There are many colors filament to choose from and they can also be custom made. A typical FDM printer uses filaments with a diameter between 1.75 mm and 2.85 mm.

With SLA printing, the materials are exclusive: they cannot be used in a SLA printer from another manufacturer. Each manufacturer designs its resin box so that it will only fit on its printer. The choice of material color is also very limited from yellow, black, white, magenta to cyan. There are different types of resin available and they are often very good presenting materials making them suitable for industrial use. The resin used in SLA printing is also quite expensive compared to equal amounts you get with filaments.

Cleaning Uncured Uv Printerresins


At some point, you will need to clean offuncured UV resins from the finished product and from the equipment. Thecuring process mentioned here involves coatings of resin drying onto theprint or finished product via a photochemical reaction.

UV-curable inks represent an alternative toconventional solvent-based products dried by heat and air, causing solvents tooxidize and evaporate.

These instructions will refer to the removal of uncured resins in anycubic photon systems, though the general procedures will remain much the same regardless of which specific resin printing system you are using.

    So What Are The Differences Between Sla Dlp And Lcd

    Regarding “light curing 3D printing”, its core is the solution around the light source problem.

    What is SLA?

    SLA is the abbreviation of “Stereo Lithography Apparatus”. The laser beam outlines the shape of the first layer of the object on the surface of the liquid photosensitive resin, and then the production platform descends a certain distance, and then the cured layer is immersed in the liquid resin. Finally, after taking the prototype out of the resin, it is finally cured and then polished, plated, painted or colored to obtain the desired product.

    What is DLP?

    DLP is the abbreviation of “Digital Light Processing”, which is digital light processing, that is, the image signal must be digitally processed before the light is projected out. The principle is to pass the cold light source emitted by the UHP bulb through the condenser lens, and use Rod to make the light uniform. The processed light passes through a color wheel to separate the light into RGB three colors Wait for more colors), and then project the color from the lens on the DMD chip, and finally the reflection is imaged on the projection screen through the projection lens.

    What is LCD?

    LCD is the abbreviation of Liquid Crystal Display. As the name implies, it is a liquid crystal projector. It is a red, green, and blue color liquid crystal panel, which is transmitted through a lens magnification and a mirror. The light source in the LCD projector is a metal halogen lamp or UHP .

    Advantages of SLA processing:

    How Does Sla 3d Printing Work

  • SLA 3D printing works by first positioning the build platform in the tank of liquid photopolymer, at a distance of one layer height for the surface of the liquid.

  • A UV laser creates the next layer by selectively curing and solidifying the photopolymer resin.

  • During the solidification part of the photopolymerization process, the monomer carbon chains that compose the liquid resin are activated by the light of the UV laser and become solid, creating strong unbreakable bonds between each other.

  • The laser beam is focused in a predetermined path using a set of mirrors, called galvos. The whole cross-sectional area of the model is scanned, so the produced part is fully solid.

  • After printing, the part is in a not-fully-cured state. It requires further post-processing under UV light if very high mechanical and thermal properties are required.

  • The photopolymerization process is irreversible and there is no way to convert the SLA parts back to their liquid form. Heating these SLA parts will cause them to burn instead of melt. This is because the materials that are produced with SLA are made of thermoset polymers, as opposed to the thermoplastics that fused deposition modeling uses.

    How The Sla 3d Printer Works

    Get $400 Off an SLA 3D Printer

    The SLA 3D printer acts much differently than an FDM 3D printer. Unlike FDM printers that use filaments like thermoplastics to print the product from the base to the top, SLA dips the product upside down into the thermoset resin. The printer uses a laser at the bottom of the dish of resin. This light source uses G-Code from the 3D file to coordinate the exact position to permanently cure the resin one layer at a time.

    Since it uses SLA to build layers, it takes a period of hours to turn 2D prints of a 3D CAD drawing into a three dimensional object. The 3D printer must dip over the same area of the resin bath in order to create all the necessary details for layering. SLA 3D printers have the highest resolution and accuracy, the sharpest details, and the smoothest surface finishes of all 3D printing technologies. Unlike thermoplastics, thermosets permanently mold after heating.

    According to, a thermoset monomer must have three or more reactive ends, with its molecular chains crosslinking in three dimensions. Post-molding, thermosets have virtually all molecules interconnected with strong, permanent, physical bonds which are not heat reversible. The SLA 3D printer uses laser UV light to meticulously hit every exact detail of the build.

    Stereolithography: Everything You Need To Know About Sla 3d Printing

    Stereolithography, or SLA, was the first 3D printing process invented, the first patent having been filed in 1984 by Charles Hull and granted in 1986. Since then, SLA has become a dominant technology, with SLA 3D printers taking over markets such as hearing aids and dental orthodontics.

    Stereolithography is the most widely known of the vat photo-polymerization processes, and has spawned similar 3D printing technologies such as DLP . But how does it work? And how will it change over the next few years?

    Stereolithography Materials / Resins

    Stereolithography 3D printers use resins, rather than the plastic filaments used in FDM. These resins are more expensive to 3D print with than filaments, and start at around $35 per liter.

    For high detail, castable resins, you may be out of pocket by as much as $400 per liter. Moreover, it is important to remember that resins do not last forever, they spoil eventually. Their shelf life is usually around a year.

    History Of Sla Printing

    Introduction to Stereolithography

    In 1981, a functional rapid-prototyping system using photopolymers was invented by Hideo Kodama, which made a solid, printed model from many layers, each of which corresponded to a sectional slice in the model. Three years later, in 1984, Charles Hull invented the solid imaging process known as stereolithography one of the earliest and most widely used forms of 3D printing along with the STL file format that is necessary for translating CAD files for 3D printers.

    Sla 3d Printing For Manufacturing

    The SLA, or Stereolithography, 3D printing method is the original process developed in the 80s. SLA uses a laser to cure liquid resin in hardened layers to build a 3D model or even product with moving parts. The SLA 3D printer offers durability, functionality, and flexibility to work within your desired parameters.

    In manufacturing, SLA 3D printing is usually used to create working prototypes before true manufacturing begins. This is because it is cheaper to 3D print the project and have a mistake than to build the product from expensive materials without a flawless product.

    Fine Features And Smooth Surface Finish

    Choosing the Right 3D Printer: FDM vs SLA

    SLA printers are considered the gold standard for smooth surface finish, with appearances comparable to traditional manufacturing methods like machining, injection molding, and extrusion.

    This surface quality is ideal for applications that require a flawless finish and also helps reduce post-processing time, since parts can easily be sanded, polished, and painted. For example, leading companies like Gillette use SLA 3D printing to create end-use consumer products, like 3D printed razor handles in their Razor Maker platform.

    Leading companies like Gillette use SLA 3D printing to create end-use consumer products, like the 3D printed razor handles in their Razor Maker platform.

    Z-axis layer height is commonly used to define the resolution of a 3D printer. This can be adjusted in between 25 and 300 microns on Formlabs SLA 3D printers, with a trade-off between speed and quality.

    In comparison, FDM and SLS printers typically print Z-axis layers at 100 to 300 microns. However, a part printed at 100 microns on an FDM or SLS printer looks different from a part printed at 100 microns on an SLA printer. SLA prints have a smoother surface finish right out of the printer, because the outermost perimeter walls are straight, and the newly printed layer interacts with the previous layer, smoothing out the staircase effect. FDM prints tend to have clearly visible layers, whereas SLS has a grainy surface from the sintered powder.
