In some cases, it’s this combination of versatility and functionality that leads to companies to initially bring SLA 3D printing in-house. One area where FDM printers traditionally reigned used to be build volume. Lets compare 3D Printed parts from a $200 FDM 3D Printer vs a $200 SLA Resin 3D Printer. Price: €4,595. Advantages. Support removal for SLA parts requires cutting away the support structures and lightly sanding the parts to remove support marks. There is also less heat emitted in the process. Varieties of resin (thermosetting plastics). More info in the description OC. With FDM printers, the precision of the machine is determined by the nozzle size and the accuracy of the extruder movements both vertically and horizontally (X/Y axis). report. The education industry has seen success in … Learn more about their meaning to better understand 3D print performance. WE talk more about these in our comprehensive 3D printing piece. Offers a heat deflection temperature (HDT) of 238 °C @ 0.45 MPa, the highest heat resistance of any material in desktop 3D printing. It creates small layers that bond together to ultimately create an object. and additive manufacturing market has undergone rapid change in recent years. For simple designs that require no supports to print, FDM requires almost no post-processing. SLA Considerations If details and surface smoothness are important for your part, SLA handily beats FDM. SLA resin materials have the benefit of a wide range of formulation configurations: they can be soft or hard, heavily filled with additives like glass and ceramic, or imbued with mechanical properties like high heat deflection temperature or impact resistance. Having trouble finding the best 3D printing technology for your needs? SLA machines are fast because they use lasers focused on specific target areas. FDM requires cooling to set the plastic, whereas SLA requires a laser to cure the resin. SLA printing works by shining a laser at precise points within a vat of resin, curing the resin in place and creating a model one “pixel” at a time. Standard, engineering (ABS-like, PP-like, flexible, heat-resistant), castable, dental, and medical (biocompatible). The inverted SLA process behind desktop SLA printers reduces footprint and cost, but heightened peel forces introduce limitations around materials and build volume, and larger parts require sturdy support structures to print successfully. When further post-processing is required, both FDM and SLA parts can be machined, primed, painted, and assembled for specific applications or finishes. SLA resin formulations offer a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics. With the file on the object layers sent to the printer, it has all the data it needs to get started. FDM 3D printers are well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts, such as parts that might typically be machined. The education industry has seen success in deploying both FDM and SLA machines. Each of these printers uses a unique process to create similar things. With the introduction of the Low Force Stereolithography (LFS) print process that powers the Form 3 and Form 3L, Formlabs has completely re-engineered our approach to resin-based 3D printing to drastically reduce the forces exerted on parts during the print process. If you watch a video of a 3D printer at work, you are likely to see a carefully programmed printing nozzle in a three-dimensional space, extruding a line of molten plastic to sketch out a clear shape. Both 3D printing technologies have been adapted and refined for the desktop, making them more affordable, easier to use, and more capable. Instead of a plastic filament, the production material in an SLA print is a vat of UV-curable photopolymer. FDM printers VS SLA printers. Our new interactive material wizard helps you make the right material decisions based on your application and the properties you care the most about from our growing library of resins. Note: There are other types of 3D printing as well, such as polyjet and SLS. 0:00. This is ideal for applications like rapid prototyping, where it allows users to quickly evaluate success and move on to another print or project. One of the main selling points for FDM 3D printers is the low machine cost. Advanced SLA 3D printers like the Form 3 offer a cartridge system, that refills the material automatically. SLA printers simply apply this process to 3D printing. The education industry has seen success in deploying both FDM and SLA machines. Professional desktop FDM printers are easier to use and more tailored to businesses, with prices ranging from $2,000-$8,000. Supported FDM prints and parts that require a high-quality finish, however, require lengthy manual post-processing. In comparison, most standard and engineering resins for SLA 3D printers cost $149-$200/L. As a project moves forward in the development, SLA 3D printing is ideal for detailed concept models or functional prototypes might require better quality and materials with different properties. FDM 3D printers form layers by depositing lines of molten material. By 3D printing parts at close to room temperature, they don't suffer from thermal expansion and contraction artifacts, which can happen during the FDM printing process. 3D Printing Costs: SLA 3D printed parts are at a higher price than FDM parts. There’s currently a struggle between two very different 3D printing technologies, known as FDM (Fused Deposition Modeling) and advanced SLA (Stereolithography). Let’s talk about how that works. To compare both types of printers, we will look for a common point between both types of technologies, in our case it will be the price of the equipment. When the printing is done, the completed part is drained, washed in solvent which removes excess resin and afterwards subjected to UV light to cure the component completely. are complex and often misunderstood terms. , a process which helps parts to reach their highest possible strength and stability. Many education institutions start with FDM printing as its low cost is ideal for students who need quick drafts and some hands-on experience with the technology. A 20% wax-filled material for direct investment casting and pressing for dental and jewelry applications. The two methods are very, very different, but they are both likely to stick around the 3D printing world. First, the printer has to be given the right information – essentially, a path to follow so that the deposited material will create the right object. SLA 3D printers are widely used in a range of industries from engineering and product design to manufacturing, dentistry, jewelry, model making, and education. Laser SLA vs. DLP 3D Printers Resin 3D printers like SLA, LFS and DLP technologies offer the highest resolutions of all 3D printing processes available on the desktop. After finding one application solved by a specific functional material, it’s usually not long before more possibilities are uncovered, and the printer becomes a tool for leveraging the diverse capabilities of various materials. Various experimental plastic filaments blends also exist to create parts with wood- or metal-like surface. As a result, SLA 3D printing is known for its fine features, smooth surface finish, ultimate part precision, and accuracy. While these machines are suitable for producing functional parts, competition at this price point is fierce, as SLA machines offer a wider range of applications and better quality prints. The use of light instead of heat for printing is another way SLA printers guarantee reliability. This is ideal for applications like rapid prototyping, where it allows users to quickly evaluate success and move on to another print or project. 764 comments. Achieving comparable quality with FDM parts will require lower layers height —thus two to four times longer printing time— or significant and time-consuming post-processing to improve surface finish. 0:00. Labor costs are the final—often forgotten—part of the equation. FDM vs SLA Materials FDM 3D printers use filaments, which are thermoplastics fed into the printer on a spool that are then melted and extruded. FDM parts, however, require additional sanding before priming or painting and need higher infill levels to be machined or bored. FDM printers struggle with particularly fine detail, or objects that need moving parts, etc. This results in much smoother surfaces, reaching layer sizes of 0.05 to 0.01 mm. They are less than one hundred microns thin, and form very quickly. Each 3D printing technology has its own strengths, weaknesses, and requirements, and is suitable for different applications and businesses. Minor training on build setup, maintenance, machine operation, and finishing. Resin vs Filament Printing Quality. Due to the price of the resin and the complexity of the printer, SLA printing is also more expensive than FDM, and more difficult to just mess around with. Various resin formulations offer a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics. Both FDM and SLA processes use support structures to facilitate 3D printing more complex geometries and their removal represents the last step in post-processing. In this process, the powdered material is heated to the temperature, which is above or below the material’s melting point. SLA 3D printers use liquid resins which are hardened by the UV light. Plastic extrusion 3D printers work with a range of standard thermoplastic filaments, such as ABS, PLA, and their various blends. Support removal for SLA parts requires cutting away the support structures and lightly sanding the parts to remove support marks. FDM printers emit much heat, and it usually demands that the user allows time for the material to cool down and harden. Is SLA printing faster than FDM? Desktop machines are suitable for an office environment. Ideal for getting visibility into complex assemblies, (micro)fluidics, mold making, optics, lighting, and any parts requiring translucency. The base moves through the tank of liquid as the object is built layer by layer, slowly raising it from the depths. The printer typically includes a base for the 3D object to built onto. Aside from cost, quality is a major consideration in comparing FDM vs SLA printers. 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. Pick from our list of applications and. Supported SLA prints only require a bit of sanding to remove support marks and achieve a high-quality finish. We dive into the science behind why SLA 3D prints are isotropic - unlike FDM prints. SLA is the preferred choice for many technical schools, universities, research institutes, and in dental and jewelry education due to the higher quality and wider range of applications. This example part was printed on the Formlabs Form 3 desktop SLA 3D printer. However, if you’re buying or learning how to use a 3D printer, it’s vital to understand the difference between FDM and SLA—so we’re going to talk about it! It can’t really create high-end prototypes. Thanks to the highly precise laser, SLA 3D printers are better for manufacturing complex parts (FDM part on the left, SLA part on the right). With the introduction of budget resin printers, SLA printing has surpassed filament printing. This makes SLA 3D printing especially ideal for engineering and manufacturing applications where material properties matter. Each layer is laid down one at a time until the part is complete. First, use any CAD software or 3D scan data to design a model, and export it in a 3D printable file format (STL or OBJ). 2. Low-cost FDM or SLA 3D printers are not really user friendly and often require many hours of tweaking and experimenting to dial-in the correct print settings. These 3D printers generally provide better reliability, higher print quality, and larger build volumes. While FDM printers produce a mechanical bond between layers, SLA 3D printers create chemical bonds by cross-linking photopolymers across layers, resulting in fully dense parts that are water and airtight. This can mean the best of both worlds: low-cost rapid prototyping coupled with high quality, functional parts for a wider range of applications.
