3D printing has come a long way since its invention in the 1980s. Today, there are two main types of 3D printing technology: resin-based and fused filament fabrication (FFF). Each has its own set of advantages and disadvantages, making them suitable for different types of projects. In this blog post, we will compare resin vs FFF 3D printing and discuss the pros and cons of each.
Resin-based 3D printing, also known as stereolithography (SLA), uses a liquid resin that is hardened by a laser to create the final object. The technology is known for its high precision and accuracy, making it suitable for creating detailed and complex objects. Resin-based 3D printing is also known for its smooth surface finish, which makes it suitable for creating objects that will be visible to the naked eye.
On the other hand, Fused Filament Fabrication (FFF) 3D printing, also known as Fused Deposition Modeling (FDM), uses a filament of plastic or other material that is extruded through a heated nozzle to create the final object. FFF 3D printing is known for its low cost, ease of use, and ability to print large objects. It is also known for its high durability, making it suitable for creating functional prototypes and end-use parts.
When it comes to cost, FFF 3D printing is generally less expensive than resin-based 3D printing. The cost of the printer itself is typically lower for FFF printers, and the filaments used in FFF printing are also less expensive than the resin used in SLA printing.
In terms of precision and accuracy, resin-based 3D printing has an edge over FFF 3D printing. The use of a laser in SLA printing allows for more precise and accurate control over the shape and size of the object being printed. Additionally, the smooth surface finish of SLA printed objects is superior to that of FFF printed objects, which can have visible layer lines.
In terms of speed, FFF 3D printing is generally faster than resin-based 3D printing. The extrusion process used in FFF printing allows for faster printing speeds, and the ability to print multiple objects at once. On the other hand, SLA printing typically involves a curing process, which can take longer.
When it comes to the materials that can be used, FFF 3D printing has an advantage over resin-based 3D printing. FFF printing can use a wide range of materials including plastics, metals, and ceramics, while SLA printing is typically limited to resins.
In conclusion, both resin-based and FFF 3D printing have their own set of advantages and disadvantages. Resin-based 3D printing is known for its high precision and accuracy, smooth surface finish, and ability to print detailed and complex objects. FFF 3D printing, on the other hand, is known for its low cost, ease of use, high durability, speed, and the ability to print large objects using a wide range of materials. Depending on the project, one or the other may be more suitable.
