How to Print Ultra PA-CF25 Filament Perfectly?

In 3D printing, filament properties directly determine the strength and accuracy of the print.

QIDI UltraPA-CF25 is a professional filament designed specifically for high-performance applications, with a 25% carbon fiber composite structure in its core providing excellent mechanical strength, high temperature resistance, and dimensional stability. This article will comprehensively introduce its pre printing drying operation, recommended printing settings, and annealing treatment, helping you easily achieve quasi industrial printing effects.

1. How to dry Ultra PA-CF25?

The characteristic of the filament absorbing water after opening is recommended to be dried before printing with this UltraPA-CF25 filament.

Drying operation:

• Make sure the surface of Ultra PA-CF25 is clean enough and free of foreign matter.

• Place Ultra PA-CF25 in a blast drying oven.

• Set the temperature of the blast drying oven to 120°C and the drying time to 4-6 hours. The specific time is determined according to the moisture level of the filament.

• Start drying.

In addition, when storing Ultra PA-CF25, it is necessary to place it in a sealed container with a desiccant and ensure that the relative humidity in the container is less than 15%RH.

2.Recommended printing parameters and accessories for printing Ultra PA-CF25

The machine used is QIDI Plus4 as an example.

Recommended accessories:

• Build plate: Use QIDI PEI plate or smooth PEI plate.

• Nozzle: Use tungsten carbide nozzle (0.4/0.6/0.8 mm) or bimetal nozzle (0.4/0.6/0.8mm).

Recommended printing parameters:

• Nozzle temperature: 300-340°C

• Bed temperature: 70-100°C

• Printing speed: 30-150mm/s

3.How to anneal Ultra PA-CF25 prints

Annealing is the practice of heating and then cooling a material to change its physical properties. In 3D printing, annealing is a key step to improve the performance of prints by eliminating thermal stress to improve strength, heat resistance, etc. However, the annealing effect is affected by many factors, such as filaments type, annealing temperature and duration. Especially for complex prints, improper operation may cause the prints to deform or warp.

For best results, it is recommended to use a blast drying oven.

• Put the prints on the tray to ensure uniform heating.

• Heat the oven to 120℃.

• Put the tray in the oven. Let the prints dry for more than 6 hours.

• Turn off the drying oven and leave the prints to cool down. Take out the tray and the prints.

4.What are the advantages of Ultra PA-CF25?

QIDI UltraPA-CF25 is a professional grade 3D printed filament designed specifically for industrial applications that require high performance and precision. Exclusive features of this product

a. Super strong mechanical performance, suitable for high difficulty printing tasks

• The inner core is reinforced with 25% carbon fiber, effectively improving the tensile strength and rigidity of the printed parts, meeting the strict requirements for strength and durability in industrial applications, ensuring that the printed parts remain strong and not easily deformed in high stress environments.

• Excellent impact resistance ensures that printed materials remain stable and intact when subjected to external forces and collisions.

b. Industrial grade precision, reducing printing failure rate

• The carbon fiber reinforced structure effectively reduces warping and deformation issues during the printing process, achieving higher dimensional accuracy, easy assembly, and is commonly used in industrial production and high-end engineering applications.

c. Excellent interlayer adhesion enhances structural stability

• By using reinforced fiber coating technology, a layer of PPA base material is wrapped around the surface of the filament, significantly improving interlayer adhesion.

• Even for thin-walled structural components, the printed parts can maintain extremely high mechanical stability.

d. Excellent high temperature resistance, expanding application areas

• Capable of a thermal deformation temperature of 196.9°C, suitable for functional components in high-temperature environments such as automotive parts and industrial equipment.

It has excellent chemical corrosion resistance and wear resistance, and can maintain stable mechanical properties for a long time in harsh high-temperature environments.

Summary: QIDI UltraPA-CF25 is an industrial grade 3D printed filament that perfectly combines high strength, high temperature resistance, and dimensional stability.
