FDM 3D printing - Fused Deposition Modeling
The way in which 3D printing has developed in recent years is nothing short of astounding with a wide range of 3D printing technologies available, one of them being FDM 3D printing.
This FDM technology is most common and is also known as Fused Deposition Modeling. This is a technology that has been patented by Stratasys and it is a technology that enables the creation of prototypes in a very short timeframe. This technology is also known as Fused Filament Fabrication or FFF 3D printing. All Tractus3D industrial printers make use of this technology. But what is it exactly and what are the things to consider to find the best FDM 3D printer that suits your needs.
What is FDM printing?
FDM 3D printing is a technology that works both horizontally and vertically, where an extrusion nozzle moves over a build platform. The process involves the use of thermoplastic material that reaches melting point and is then forced out, to create a 3D object layer by layer. As the design takes shape, it is clear to the see each layer as a horizontal cross section. Following the completion of one layer, the nozzle of the printer is lowered in order for the next layer of plastic to be added to the design. Once the object has been created, the materials that are used to support the object can then be removed.
Many businesses use FDM 3D printing technology as it allows the creation of detailed and intricate objects. Therefore, engineers are using it to allow them to test parts for fit and form. It is a technology that is now assisting the creation of small parts and specialised tools that would once take a lot longer to produce.
Every single 3D printer that we have uses FFF 3D printing with the most common 3D printed material being Polylactic Acid, also known as PLA. However, we do not stop there because our T650P can also use other materials such as polyetherimide (PEI) and Polyether ether ketone (PEEK).
The technology that drives FDM forward was invented in the 1980’s which was down to the evolution of technology that became commercially available. We have also adopted this FFF 3D printing technology and that enables us to deliver 3D printing systems that can provide a huge range of benefits.
How does FDM 3D printing work?
In the same way as other forms of 3D printing, FDM uses a digital design that is uploaded to the 3D printer. There are a lot of different polymers used, such as ABS, PETG, PEI and PEEK. These take the shape of plastic threads that are fed from a coil and through a nozzle. The filaments are melted and fed onto the base, known as a build platform or table with the base and the nozzle, both of which are controlled by a computer. The computer works by translating the object and its dimension into co-ordinates that make it possible for the nozzle and base to follow.
As the nozzle moves across the base, the plastic cools and becomes solid, forming a hard bond with the previous layer. At this point the printhead goes up in order for the next layer of plastic to be laid. As always, 3D printing is efficient and fast but the time it takes to create an object does depend on its size. Smaller objects that are around several cubic inches can be created quickly but larger, more complex object will take longer.
What is FDM 3D printing used for?
The use of 3D printing is highly publicised but what is FDM 3D Printing or FFF 3D printing used for? Many different industries choose to use FDM 3D printing including the automotive industry and a wide range of consumer goods manufacturers. They use FDM because it helps to aid their product development, their prototyping and their manufacturing process.
Manufacturers of certain products use FDM 3D printing because of the thermoplastic that is used during development is perfect for anything ranging from Children’s toys or even sports equipment.
Prior to a product being taken to the mass market, it is important that objects are tested vigorously. Therefore, the use of thermoplastics is ideal for creating prototypes because they can endure heat, chemicals and mechanical stress. Along with this, as FDM printing has the ability to create extremely detailed objects, it makes it the ideal choice for those industries that use need to create parts that need to be tested for fit and form.
However, it is not just about prototyping because FDM is also used to create end-use parts, especially small parts that have a lot of details. In fact, it is common for thermoplastics to be used for food packaging and drug packaging and so, it is a popular technology in the medical industry. Here you can find some case studies about the use of 3D printing.
For businesses looking for a viable option that can deliver results, FDM 3d printing offers the perfect solution. It is competitively priced and the best FDM 3D printers can deliver results efficiently and effectively.

How do you find the best FDM 3D printer?
As explained in the text above, the right FDM 3D printer will help you utilizing the benefits of the technique. You should pay special attention to a couple of things when you are searching for the best FDM 3D printer that suits your needs. Factors such as build volume, printing material, technical specs and service will influence the price of the FDM printer.
1. Build volume
One of the most important things to consider when searching for your best FDM 3D printer is the size of the designs you want to print in 3D. Also determine upfront if you are going to 3D print batches of multiple objects. The size of the design and the batch size affect the build volume you need.
2. Printable materials
There are many different print materials (filaments) available for FDM 3D printers. Each material has its pros and cons. What kind of material do you want to print? Be aware that not every FDM printer can handle all types of materials. For example high performance materials like PEEK need a higher extruder temperature, which the majority of FDM 3D printers do not offer.
Certain manufacturers have a closed filament system, meaning that you can only use the printing materials from a particular brand (often their own brand). On the other hand, there are also manufacturers with an open filament system, offering you freedom of choice. In that case you are free to choose your prefered filament brand, which is almost always less expensive.
3. Technical specifications
Finding your best FDM 3D printer also means looking into the, sometimes complicated, technical specifications of the machines. We already discussed the importance of the size of the print area (1. Build volume). Other important specifications are:
Extruder(s): Each 3D printing material has a different melting point, that is why the extruder (or nozzle) temperature of the FDM 3D printer is vital. Make sure that the extruder can handle the material you want to print.
Resolution: The thickness of the layers affect the quality of the output. A higher resolution means thinner layers, which are less visible. This is often measured in microns, a resolution of 10 microns is a layer thickness of 0,01 millimeters. Make sure its the best FDM 3D printer for the quality you need, check if the minimum and maximum resolution meet your requirements.
Speeds: There are two different speeds to consider, travel speed and printing speed. Printing speed is the actual speed each layer is 3D printed and travel speed is the speed at which the FDM printer moves from one point to the other while its not printing. Be aware that speed settings can also influence the quality of the output.
Other features which improve the 3D printing process are a automatic build plate calibration, out-of filament detection and a closed chamber.
As is possible with any machine, some parts of it can malfunction or get worn over time. Even with the best FDM 3D printer you can experience issues. Look up the warranty term at the manufacturer and in some cases signing a service level agreement could be interesting. Its also wise to check the support level by phone, email and/or live chat.
