The Pros and Cons of Fused Deposition Modeling (3D Printing)

Fused deposition modeling (3D printing) is a process that prints objects by melting and solidifying a filament. It does so without the need for supports and other structures. It is a good choice for prototyping, but it is not recommended for high-quality parts. Here are some cons of FDM. Read on for more information. But before you start a 3D printer, consider this information.

FDM is a popular process for making 3D printed objects. This process uses hot-melt thermoplastic materials to create a solid part. In a standard 3D printer, layers are around 16 microns. Some models are capable of printing colors. For example, the DaVinci Color by XYZPrinting prints in 10 million colors. The technology has since become commercially viable, and several manufacturers have sprung up in the industry, such as Makerbot. Here is a great post to read on quality 3D printing technology.

While FDM isn't the highest-quality 3D printing technology, it is the most affordable and accessible method of rapid prototyping. Moreover, the most popular FDM printers can print accurate models as small as 50 microns. If high-quality printing is the goal, SLA or Binder Jetting are better. FDM is a great choice for low-cost prototyping, because it can produce cheap copies of designs. It also has some use in the medical, art, and aerospace sectors.

Fused deposition modeling is the most common form of 3D printing. This technology uses melted plastic filament to build up objects layer-by-layer. This method is very flexible and inexpensive, and offers many benefits over Carbon DLS and HP MJF. It's also much more efficient than other forms of 3D printing, and its parts are generally more durable than many other types of plastics. The process is also highly automated. It doesn't require a lot of human effort to create a part, and it can be post-processed like any other plastic part.

One of the best features of FDM is that it is flexible and can be printed in any shape. Its high level of flexibility makes it a good option for making prototypes. The filaments that are used for FDM are made of polylactic acid, which has a low melting point. Using polylactic acid allows FDM to create more complex objects. These results are promising and will eventually help make FDM an efficient tool in engineering.

The disadvantage of FDM is void formation. These voids are a major drawback of 3D-printed parts, as they tend to be mediocre in terms of mechanical properties. Future research will need to investigate the interrelation between machine parameters and material properties to improve the pertinence of FDM. There are two major approaches to void formation: a method using polymer nanocomposites, and a method that uses biomaterials as fillers. See page linked here for more info on 3D printing.

The first is to remove the support material before printing the part. Support structures are usually made of HIPS or PVA. In order to remove these supports, one needs a dual printer with a dedicated support material. This results in higher costs per print and a smaller print area. Furthermore, the support material is not as flexible as non-dissolved support material. This process is not suitable for many applications, including small parts and prototypes.
