From creating intricate jewelry to printing human organs for medical research, the applications of 3D printing are endless. Resin 3D printing specifically is ideal for producing complex parts and components with extraordinary detail.
This article will delve into the exciting possibilities of resin 3D printing and provide a review of the best resin 3D printers on the market.
What Is Resin 3D Printing?
Resin 3D printing is a vat photopolymerization form of additive manufacturing that uses liquid resins to create objects layer-by-layer. A light source cures liquid resin, solidifying it in layers until the entire product has been printed.
Due to the thin layers and precision of the light, resin 3D printers can produce models with higher detail, accuracy, and a smoother finish than other 3D printing technologies.
Since Charles Hull invented the first resin-based 3D printer in 1984, the technology has come a long way. Several generations of resin 3D printing technology have been developed, including Stereolithography (SLA), Digital Light Processing (DLP), and Masked Stereolithography (mSLA).
Each emerging technology significantly improves over its predecessor and broadens the range of objects for 3D printing. mSLA, the latest generation of SLA 3D printing, uses masks to control where light reaches the build plate. Masked light ensures that only specific areas are exposed to the light, allowing for highly detailed prints that can be printed faster than traditional SLA printers.
Since it projects pixels straight on, it creates more consistent parts from edge to edge. Plus, the LCD panels used in this process are much more readily available than DLP chips–and at resolutions of 8k and beyond. This leads to overall faster printing speed and reduces the cost of producing objects.
Resin 3D Printing vs. 3D Printing with Filaments
Fused Deposition Modeling (FDM) 3D printing uses heated plastic or metal filaments to produce objects layer by layer. The printer feeds a solid polymer filament into an extruder assembly where a motor drives it through a thermal core. The materials heat close to their melting point before they are extruded onto a build plate through a nozzle. The melted materials are deposited layer-by-layer until the entire object is formed.
Though it’s a popular 3D printing technique, there are some drawbacks to filament 3D printers. They can’t print with the same level of quality and detail as resin 3D printers, and they tend to print much more slowly than resin printers.
Resin 3D printing can also produce more accurate and detailed objects than filament 3D printing. The thinner layers and precision of the light result in smoother surfaces with higher resolutions. Due to the liquid nature of resins, they can create complex shapes or internal structures that are impossible to make with filaments.
