Wide range of applications: FDM printers are suitable for a wide range of applications such as making prototypes, toys, home furnishings, parts and small batch production.
However, there are some limitations to FDM printing for beginners. Chief among them is the relatively low printing accuracy and inferior surface quality to some other technologies. In addition, some complex geometries may require support structures that require subsequent manual processing.
II. Stereolithography (SLA) / Light Curing
SLA technology can also be suitable for beginners, but it is usually suited for those who have higher demands for high precision and excellent surface quality. Here are the reasons why SLA printers are suitable for beginners:
High precision and excellent surface quality: SLA printers are usually capable of very high precision, making them suitable for projects that require a high level of detail and smooth surfaces.
No need for support structures: Unlike FDM, SLA printers usually do not require support structures, so post-processing requirements are lower.
Material Versatility: SLA printers use liquid resin as the raw material, so a wide range of different resins can be selected, including clear, soft and high temperature resins.
Learning curve: Although SLA printing technology is superior in terms of accuracy, it may take more time to get used to its operation and post-processing techniques.
Areas of application: SLA is suitable for high precision applications such as jewelry, dentistry, engineering models, and medical devices.
However, SLA printers are usually expensive and resin materials are relatively expensive. In addition, special safety measures are required to protect eyes and skin due to the use of UV light sources.
III. Selective Laser Sintering (SLS) / Selective Laser Sintering
SLS technology is an advanced 3D printing technique that is usually less suitable for beginners. Here is some information about SLS printers:

Application areas: SLS is suitable for the manufacture of parts, tools, prototypes and medical implants and other fields.
Fourth, digital light processing (DLP) / Digital Light Processing
DLP technology, similar to SLA, is a light-curing technology that is usually used to manufacture high-precision models and parts. Here is some information about DLP printers:
High speed printing: DLP printers usually print faster because they can irradiate an entire layer at the same time.
High precision and surface quality: DLP technology typically enables high precision and excellent surface quality for applications that require high resolution.

For beginners, FDM technology is usually the best choice because of its low cost, ease of use and extensive community support. However, if you have a higher demand for high precision and excellent surface quality, then SLA and DLP technologies are also good choices, although they can be a bit more expensive and complex. Above all, whichever type of 3D printer you choose, be prepared to learn and explore, as 3D printing is a creative and fun field that can offer you endless possibilities.
The cheapest type of 3D printing is usually a printer based on Fused Deposition Modeling (FDM) or fused deposition modeling technology. Here are some reasons why FDM technology is usually more affordable:
Low-cost printers and materials: FDM printers are usually relatively inexpensive for individual users and beginners. In addition, the printing materials used in FDM, such as PLA (polylactide) and ABS (acrylonitrile butadiene styrene copolymer), are relatively inexpensive. This reduces initial investment and running costs.
Low energy consumption: FDM printers typically use thermal nozzles to melt plastic filaments and deposit them into layers. Compared to other 3D printing technologies, such as laser sintering or light curing, FDM consumes less energy and therefore saves on electricity costs.
Wide market: Due to the wide popularity of FDM technology, there are many different brands and models of FDM printers available in the market, which increases competition and helps to reduce prices.
Low Maintenance Costs: FDM printers are usually easy to maintain as they do not have complex laser systems or liquid photosensitive resins, parts that can require expensive repairs.
Open source community: there are many open source FDM printer designs and groups that share information and designs, allowing people to build their own 3D printers, further reducing costs.
It is important to note that while FDM technology is one of the cheapest types of 3D printing, it may not be as good as some of the other high-end technologies, such as light curing (SLA) or selective laser sintering (SLS), in terms of print accuracy and surface quality. Therefore, if you need higher precision and quality prints, you may want to consider other types of 3D printing technology, even though they are usually more expensive. However, for many home users, schools, and small businesses, FDM technology offers an affordable entry option for most basic 3D printing needs.
