-Stereolithography, the innovation behind the majority of resin 3D prints, is usually referred to as 'the mother of all 3D printing modern technologies' as well as is thought about among the most widely made use of methods for generating top notch 3D prints. Below at Materialise, we have been making use of Stereolithography considering that 1990. Time to chat a bit more regarding this technology as well as our latest resins.
Uv Resin 3D Printer
The Modern technology: It's all about UV Lasers
The modern technology behind (most) resin 3D prints is known as Stereolithography. And here's the one-minute description of how Stereolithography works:
- In the initial instance, the roller of the printer spreads out a razor-thin layer of liquid polymer. Considering that this layer is liquid, it will certainly spread out over the entire system making certain that each layer has a regular thickness
- The fluid polymer we use is UV sensitive. When struck by a computer-controlled UV laser, the resin will transform from a liquid to strong state. Essentially, the laser "draws" the details of the print into the resin layer as well as hardens the components that it touches.
The parts that are not touched by the laser will certainly remain liquid
- These two steps are repeated over and over as well as over again. The version is lowered by a portion, and the roller spreads out a brand-new layer. The laser then solidifies specific areas of that layer, which will enter into your 3D print. This is duplicated till the design is completed
As soon as the printing process is completed and also the whole object has been printed, the print is raised from the resin tank. The excess liquid will merely move away and also can be recycled for various other prints. The prints after that have to be removed as well as completed manually (i.e. eliminate assistance structure, smoothen surfaces, spray-paint surfaces, etc.).
The Resins: From Tiny Information And Facts to Mammoth-Size
There is more than one material made use of with this technology. Actually, we provide four different Stereolithography-based resins that had their own attributes. However, these materials likewise share some qualities: they showcase smooth surface areas and also are wonderful for post-processing.
Mammoth resin: Mammoth resin is published on among the largest printers out there ... you guessed it, the Materialise Mammoth printers (that's additionally the printer you saw in the video clip above). Previously this resin was referred to as Paintable resin. These printers can print huge parts up to a dimension of 2100x700x800 mm, which can be spray-painted in a number of colors.
Transparent resin: Likewise published on our Monstrous printers, Transparent resin is (surprise, surprise) clear and can be purchased in a number of shades. Actually, it is the only transparent material that we currently provide at i.materialise.com. It can additionally be purchased for parts up to a dimension of 2100x700x800 mm.
Gray resin: Gray resin is the terrific all-rounder. It includes a fantastic degree of information, appropriates for tiny and mid-size models, and also includes a smooth, gray surface. This gray color makes it ideal for hand- or spray-painting tasks. That's why this resin is so preferred among the range modeling community.
Standard resin: Our most recent enhancement to the resin family. Typical resin comes at a low-budget price while supplying very detailed results. To save some even more money, you could also buy Basic resin with support framework, meaning much less time spent in post-processing.
