Are you ready to transform how you design and create objects? Take a look at Fused Deposition Modeling (FDM) The revolutionary 3D printing technology that’s making waves across the globe. With FDM it’s possible to make your ideas come to life, layer-by-layer by layer, using melt-in-the-dark plastic filament. The most appealing aspect?
FDM is cost-effective, flexible, and highly adaptable. In everything from aerospace and consumer goods, FDM is finding its way into every sector altering how we produce and develop. However, as with all technologies, FDM has its limitations like visible layer lines as well as limited power. Let’s explore this world called Fused Deposition Modeling (FDM) and find out how it is changing manufacturing’s future.
History of Fused Deposition Modeling
Fused Deposition Modeling (FDM) was created in the latter half of the 80s, through S. Scott Crump, co-founder of Stratasys. The concept of FDM was conceived by Crump when he was constructing a toy frog for his daughter with hot glue guns. He discovered that he could utilize the same technique to create 3D objects and the concept for FDM was developed. Crump along with his wife Lisa established Stratasys in 1989.
The company was founded in 1989. the company launched the initial FDM machine, called the 3D Modeler, in 1992. The initial FDM machine was made of ABS plastic filament and could produce objects that had resolutions that were 0.010 inches. Since that time, FDM has evolved and advanced, thanks to advances in software, materials, and even hardware. At the present, FDM is a widely utilized 3D printing technique that’s changing the way we make and design objects.
How FDM Works
FDM technology involves melting a plastic filament before extruding it out of a nozzle that moves in X, Y, and Z directions in order to form an object layer by layer. The process involves many steps:
Step 1: Designing the Model
The initial step in FDM is to create the 3D model with computer-aided designing (CAD) software. The software generates an electronic file that includes instructions for the printer to print the model. The model is created by hand or downloaded directly from the database of already-designed models.
Step 2: Slicing the Model
It is divided into thin layers with an application called the slicer. The slicer transforms a 3D representation into a sequence composed of 2D cross-sections. Each cross-section is a part of the final object.
Step 3: Preparing the Printer
Before printing for printing, the FDM printer must be ready. This includes placing the plastic filament in the printer, heating the printer bed, then checking the printer’s calibration so that the printing is precise.
Step 4: Printing
Once the printer is in place it begins creating the image. The filament of plastic is then melted and extruded out of the nozzle, and it can move in X and Z directions in order to produce layers of the item. The printer begins with the first layer and adds layers by layer.
Step 5: Post-Processing
After the printing has been completed after which the object is eliminated from printer. Certain post-processing steps may be necessary for example, removal of support material as well as sanding or painting, based on the specifications that the product.
Advantages of FDM
FDM has many benefits over the other 3D printing techniques:
» Cost-efficient: FDM printers are relatively inexpensive, and the plastic filaments that are used to print FDM are also more affordable in comparison to other materials that are used for 3D printing.
» Wide variety of materials: FDM can use a variety of materials, such as ABS, PLA PETG, Nylon, and many more.
» High accuracy: FDM can produce objects with high precision and resolution, dependent on the settings of the printer.
» Simple to use: FDM printers are relatively user-friendly and do not require any technical know-how.
» Customizatin: FDM is able to create customized objects that have unique sizes and shapes which makes it ideal for small-scale manufacturing and prototyping.
Disadvantages of FDM
FDM also has its own drawbacks:
» The layer lines: FDM produces objects through making layers. This may result in visible layer lines in your final item. It can be reduced by altering the settings of the printer but it’s an inherent limitation of the technology.
» Limited strength: FDM objects can be robust, but they are generally weaker than objects manufactured with other methods of production such as injection molding, or CNC cutting.
» Support structure: FDM objects with overhangs or complex shapes might require support structures. These are difficult to remove following printing.
» Speed of printing: FDM printing can be slow, especially when printing complicated or large objects.
Applications of FDM
FDM is extensively used in many industries, such as:
» Aerospace: FDM can be used to make lightweight components for aircrafts and spacecraft. FDM is also employed to develop prototypes to test and develop.
» Automotive: FDM can be used to develop custom parts and prototypes of vehicles which include racing cars as well as concept cars.
» Medical: FDM uses FDM to make custom-designed prosthetics implants, prosthetics, and surgical instruments. FDM is also used in surgical planning and for modeling.
» Consumer products: FDM can be used to make a range of consumer items, such as cellphone cases, toys, and household products.
» Educational: FDM is used in schools and universities to teach the art of 3D printing.
How FDM Transforming the Future of Manufacturing
The use of Deposition Modeling (FDM) has changed the way manufacturing is done in numerous ways. Here are some ways in which FDM has changed the game:
» Modification: FDM allows for highly customizable creation of objects. With the capability of creating layers of objects, FDM offers the flexibility to create objects customized to meet specific requirements and specifications.
» Cost-effective: FDM can be a low-cost method for production. It is a great alternative to costly molds and tooling which makes it a great option for small-scale production.
