FDM 3D printer Or Resin 3D printer? Which One is Better for Home Use?
With the development of science and technology, 3D printing technology is no longer limited to laboratory or professional use. 3D printing has entered our daily lives, and more and more people are starting to use 3D printers at home to print their favorite figures, decorations, or various toys.
Among the many 3D printing technologies, only two are suitable for home use: FDM technology (FDM 3D printer) and photopolymerization technology (resin 3D printer). Which one is more suitable for beginners? How to choose the first 3D printer? How should a beginner choose a printer? Which 3D printer is suitable for home use? Which printer is suitable for children? Today, ToAuto will introduce these two 3D printing technologies and their differences in detail, so that you will have the focus when choosing a 3D printer.
FDM 3D printer
FDM (Fused deposition modelling) is the most widely used and most commonly used printing technology for desktop 3D printers: the thermoplastic filament is heated and extruded through the nozzle, and the plastic melt is accumulated and solidified on the printing bed layer by layer until a complete model is printed.
FDM 3D printing technology has been widely used in automobile production, education, cultural and creative, art, design, medical and other fields. FDM 3D printers also provide a cost-effective method for product development and rapid prototyping of small businesses, and are also widely used teaching tools in schools.
If used for home use, FDM printers can quickly produce simple replacement parts, and many people use this printer to make exquisite decorations and even clothing.
FDM 3D printers have many advantages: various of filaments; simple to operate and use; larger printing area; high molding accuracy, good printing performance, and multiple colors.
Disadvantages: The surface of the printed object is rough.
Resin 3D printer
Resin 3D printer uses photopolymerization technology: the liquid photosensitive polymer is cured by ultraviolet light. Ultraviolet rays penetrate the transparent bottom of the resin barrel to selectively cure the resin, and the liquid photosensitive polymer is stacked layer by layer in the barrel to finally form the required model. Each time a layer is printed, the forming platform will be lowered to the initial position, and the prints fixed on the platform will appear to rise from the resin pool. SLA, MSLA, and DLP are all photopolymerization technologies, and the difference is that they use different light sources.
Resin 3D printers can print models with smooth surfaces and perform precise processing of details. Resin printing speed is usually faster than FDM, and the adhesion between the printed layers is stronger, so resin printer prints a stronger model.
The difference between FDM and resin printing
Although there are printers of various sizes on the market, there are generally few overflows. When the filament melts, odour will slightly affect the air quality, so please don't stay near the machine for too long. It is easier to clean up after printing.
Resin has a peculiar smell and is a chemical, so special cleaning tools are required. At the same time, ToAuto highluy recommends that you wear personal protective equipments when using resin printers. After printing, you need to clean the printer and printing with 95% isopropyl alcohol to dissolve the uncured resin on the surface.
The advantages of resin printing: amazing printing details, smooth surface of the finished product, fewer moving parts on machine, high success rate, cheap and reliable, low noise.
Disadvantages: Smaller print bed size, need lots of learing, and different resins perform differently. The materials are toxic, so be careful when handling them. The resin consumables are expensive and smell great.
