How to Print PPS-CF Filament Perfectly?
Table of Contents
QIDI PPS-CF is a carbon fiber reinforced polyphenylene sulfide (PPS) composite material. The combination of PPS and carbon fiber endows PPS-CF with excellent properties, including outstanding solvent resistance, corrosion resistance, heat resistance, flame retardancy, ultra-low moisture absorption, and exceptional mechanical performance. This article will provide a comprehensive overview of pre-print drying operations, recommended print settings, and annealing treatments to help you achieve near-industrial-grade printing results with ease.
1.How to dry Ultra PPS-CF?
The characteristic of the filament absorbing water after opening is recommended to be dried before printing with this PPS-CF filament.
Drying operation:
- Ensure that the surface of the PPS-CF filament is sufficiently clean and free of foreign objects.
- Place the PPS-CF filament into a blower dryer.
- Set the temperature of the dryer to 120 ° C and the drying time to 8 hours. The specific time is determined according to the humidity level of the filament.
- Start drying.
In addition, when storing PPS-CF filaments, it is important to place them in a sealed container with a desiccant and ensure that the relative humidity inside the container is less than 20% RH.
2.Recommended printing parameters and accessories for printing PPS-CF
When using PPS-CF filament printing, in order to ensure successful printing and printing quality, we recommend users to use the following accessories and printing parameters (using QIDI Plus 4 as an example):
Recommended accessories：
- Build Plate：QIDI PEI Plate、Smooth Plate
- Hotend：Hardened Steel Nozzle ( 0.4 / 0.6 / 0.8 mm) or Bimetal Nozzle ( 0.4 / 0.6 / 0.8 mm)
- Drying box：During printing, please put the filaments into the drying box to prevent the wet filaments from affecting the printing quality.
Recommended printing parameters：
- Nozzle temperature: 320-350°C
- Bed temperature: 100-110°C
- Printing speed: 30-100mm/s
- Printing Fan：0～30%
3.How to perform annealing treatment on PPS-CF printed parts?
Annealing is the process of heating and then cooling materials to alter their physical properties. In 3D printing, annealing is a key step in improving the performance of printed parts by eliminating thermal stress to enhance strength, heat resistance, and so on. However, the annealing effect is influenced by various factors such as material type, annealing temperature, and duration. Especially for complex models, improper operation may cause deformation or warping of the model.
For optimal results, it is recommended to use a blast drying oven.
Detailed annealing treatment of PPS-CF printed parts:
- Place the items on the tray to ensure even heating.
- Heat the box to 120 degrees Celsius.
- Put the printed copies into the box. Let it stand and dry for more than 6 hours.
- Turn off the drying oven and let the items sit until they cool down. Remove the tray and take out the printed copies.
4.What are the advantages of the QIDI PPS-CF?
a.Ultra-high resistance to heat and flames, provides reliable guarantee for use in key areas
QIDI PPS-CF has a heat deflection temperature of up to 264°C and can achieve a UL-94 V-0 flame retardant rating.
b.Excellent solvent and chemical resistance, ideal for use in the chemical industry
It is almost insoluble in any solvent at temperatures below 200°C and can resist acids, bases and salts well under normal conditions.
c.Ultra-low water absorption, the best choice for demanding moisture-proof requirements
With an extremely low moisture absorption rate of just 0.05%, QIDI PPS-CF is suitable for use in humid or underwater environments such as pump impellers, marine parts, and diving equipment components.
d.Excellent mechanical properties to meet high precision requirements
PPS-CF combines the stiffness of polyphenylene sulfide (PPS) with the reinforcing capabilities of carbon fiber to provide excellent stiffness, bending strength and tensile strength.
QIDI PPS-CF has excellent resistance to solvent, corrosion, heat and flames, ultra-low water absorption and excellent mechanical properties. Whether in aerospace, automobile manufacturing, or in the fields of electronic equipment and chemicals, QIDI PPS-CF has shown extraordinary application prospects.
