Any 3D printer system creates objects from 3D files layer by layer, but each system has its own unique approach. To avoid confusion, we’ve made an infographic of every printer system for easy comparison. They are organized into groups, systems, system names, materials used and brands that are available in the market.
A dlp 3d printer is a powerful tool to print and show complex designs, such as a façade or textured roof. These complex and intricate features which are normally a challenge or impossible to create accurately by hand are now easily achieved through 3D printing. This will enhance the visual experience and give customers a better understanding on how the features would look in real life. The model can be shown how shadows and sunlight appear at different periods of the day which makes it look more real.
To the question of how each technology works and what the resulting work looks like What advantages and disadvantages does each printing system have? In the following chapters, the different systems how it works in detail
Fused Filament Fabrication (FFF)
It is the most popular system for desktop printers. work fast and the lowest cost. FFF is a printing that starts with a long filament called a filament. It is drawn from the feed roll into the heated section to melt the material. Once it has melted, it will be injected from the print head, which will be dragged according to the programmed pattern. while the material is injected in layers it will cool down and hardened to support the material to be stacked in subsequent layers until the completion of the whole piece
In addition to being the lowest cost system, there are also many materials and colors to choose from, including ABS, PLA, Nylon or other exotic materials. such as carbon, bronze, or wood composites.
FDM is the best choice for prototyping applications with speed and low cost widely. Today’s printing is very advanced can be printed on the mechanical part And electronics as well, such as drones, but some designs and material restrictions. Therefore, the use of FDM is not recommended for granular work. and highly complex.
Stereolithography and Digital Light Processing
Light solidified liquid resin system It is mostly used in very detailed work, sculpture and jewelry work.
Both Stereolithography (SLA) and Digital Light Processing (DLP) create 3D parts out of liquid resin. (Photopolymer) uses light to shape the workpiece, causing it to harden in layers.
In the forming of the workpiece The printing press is immersed in a translucent tray filled with resin. When the printing plate is immersed into the bottom of the light generator tray It will project the workpiece layer by layer through the tray to harden the resin. Once the resin has hardened, the printing press will move as high as the next layer’s height. New resin water will flow in its place. Then the light generator will project the next layer. It’s like this, layer by layer until the job is finished There are currently two types of printers in this system. It differs with the light source in which the SLA uses a laser light while the DLP system uses the light from the projector.
This type of 3D printing technology is also available in desktop machines. The available materials are currently limited to resin only. But there is going to be a variety of materials being produced to increase strength and flexibility of the workpiece.
Both SLA and DLP 3D printers are high resolution systems. Get a smooth and smooth surface. It is often used for very detailed work such as sculpture Jewelry, prototyping, usually this type of printer has a small print area therefore cannot print large jobs.
This system printer is often used in large industrial plants. However, at present, desktop-level machines are already seen. and is being pushed into the mainstream of 3D printing. Available materials include polyamides (or nylon), polystyrenes and thermoplastic elastomers.
