Nylon Filament for 3D Printers
For the nylon filament you can use the filtering system according to the type of material, the color, the section and the brand.Read More
Properties, characteristics and uses of ABS filament for 3D printers
- it is a more technical polymer than other filaments.
- It is a thermoplastic available in powder form for SLS technologies and as a filament for FDM technologies.
- Nylon filaments are a good alternative to polycarbonate because they are easier to print on.
- This filament has a better shelf life.
- More suitable for printing parts that require resistance over time.
Why print in 3D with Nylon filament?
Each 3D printing filament has its own features and characteristics. When it comes to Nylon filament, the first thing to note is the quality of the finish (as long as it is dry): it leaves a smooth and silky finish, very pleasant. The coating adherence of Nylon is excellent producing prints without failure, once you get the point. Details are also reproduced well, so when it comes to small or detailed prints, Nylon usually gives good results.
Nylon is extremely resistant.
When printed on thicker pieces, with higher density of filling and wider wall thickness, it produces a very strong piece that can withstand significant impact. However, when printed on thin pieces it becomes very flexible, which also gives it strength and prevents it from breaking.
The friction coefficient of Nylon is very low.
What is this friction coefficient? It means that Nylon is ideal for moving parts. If, for example, you need to print a hub for an axle, or a gear that is going to turn at many revolutions, Nylon is an excellent choice since no lubrication is needed due to the low coefficient of friction.
High resistance to traction
A rope or yarn made of nylon will present a huge resistance to traction. That is why this filament is usually used in fishing line, ropes, cables etc.
Print in 3D with Nylon Filament
When printing in 3D with Nylon filament, remember that you must take into account these general guidelines, without prejudice to review the instructions of each brand:
The optimum printing temperature for nylon is usually around 240C-260C, according to the instructions of each brand.
The warm base should be at 80C or more, and watch out for sudden changes as Nylon is sensitive to cooling too quickly, and that causes deformation.
To facilitate adhesion it is recommended to use an adhesive such as dimafix.
The coating fans should be turned off, and you should be careful to be in a dry and draught-free environment.
Tips for conserving the Nylon Spools
Nylon is hygroscopic, which means it will absorb water. In fact, nylon can absorb 10% of its water density in just 24 hours! So make sure you keep it closed in an airtight bag or container with desiccant. If the nylon spool is badly preserved and has absorbed water before printing it will result in bad finishes with loss of detail on the piece. In the worst case, when printing, you will hear the popping, which will also give the print a very rough surface. Nylon delamination can also be caused by moisture, but it is usually a symptom of not being hot enough.
If for whatever reason you see that the Nylon filament coil has picked up moisture, you can dry it by putting it in the oven at 85°C for 5 or 6 hours, watching it from time to time. You can also put a few desiccant bags in the box or bag and wait for the next day.
