Yes, 3D printer filament quality matters a lot for the success and quality of your 3D prints. Filament quality can affect the extrusion, adhesion, durability, appearance, and performance of your 3D printed objects. Poor quality filament can cause clogging, jamming, warping, cracking, stringing, and other printing defects. Therefore, it is important to choose high-quality filament from reputable brands and suppliers, and to store and handle it properly.
3D printer filament is the material that is fed into a 3D printer to create 3D printed objects. It is usually made of thermoplastic polymers, such as PLA, ABS, PETG, Nylon, TPU, etc. Filament comes in different diameters, colors, and properties, depending on the type of 3D printer and the desired characteristics of the 3D print.
Filament is typically wound on a spool and fed into the 3D printer’s extruder, which heats up and melts the filament, and then deposits it layer by layer on the build plate, following the instructions from a 3D model file. The melted filament cools down and solidifies, forming the 3D printed object.
How does filament quality affect 3D printing?
Filament quality can have a significant impact on the 3D printing process and the final result. Some of the factors that determine filament quality are:
Diameter consistency: Filament diameter should be consistent throughout the spool, without any significant variations or fluctuations. This ensures that the extruder can feed the filament smoothly and accurately, without over- or under-extruding. Diameter inconsistency can cause uneven layers, poor surface quality, dimensional inaccuracy, and extruder problems.
Moisture content: Filament should be dry and free of moisture, as moisture can cause bubbles, pops, hisses, and steam during extrusion, affecting the quality and strength of the 3D print. Moisture can also degrade the filament over time, making it brittle and prone to breaking. Some filament materials, such as Nylon and PVA, are more hygroscopic than others, meaning they absorb moisture from the air more easily. Therefore, filament should be stored in a sealed bag or container with desiccants, and dried before use if necessary.
Impurities and additives: Filament should be pure and free of any contaminants, such as dust, dirt, metal particles, or other foreign materials. Impurities can cause clogs, jams, or nozzle damage, as well as affect the color and appearance of the 3D print. Some filament manufacturers add additives, such as pigments, stabilizers, or modifiers, to enhance the properties or aesthetics of the filament. However, these additives should be well-mixed and compatible with the base material, and not compromise the filament quality or performance.
Tensile strength and flexibility: Filament should have adequate tensile strength and flexibility, depending on the intended application and use of the 3D print. Tensile strength is the ability of the filament to withstand pulling forces without breaking, while flexibility is the ability of the filament to bend or stretch without snapping. Filament with low tensile strength or flexibility can break during feeding, extrusion, or post-processing, resulting in failed prints or damaged parts. Filament with high tensile strength or flexibility can produce more durable and resilient 3D prints, suitable for functional or mechanical purposes.
To ensure the best 3D printing results, it is advisable to choose and use high-quality filament from reliable and reputable brands and suppliers. Some of the tips and best practices for choosing and using high-quality filament are:
Check the specifications and reviews: Before buying filament, check the specifications and reviews of the filament, such as the diameter, tolerance, material, color, temperature, etc. Compare the specifications with the requirements of your 3D printer and the 3D model. Read the reviews from other users and experts, and look for any feedback or issues regarding the filament quality, performance, or compatibility.
Buy from authorized dealers: Buy filament from authorized dealers or distributors, who can guarantee the authenticity and quality of the filament. Avoid buying filament from unknown or untrusted sources, who may sell counterfeit, expired, or defective filament. Also, check the warranty and return policy of the filament, in case you encounter any problems or defects with the filament.
Store and handle filament properly: Store filament in a cool, dry, and dark place, away from heat, moisture, and sunlight. Use a sealed bag or container with desiccants, or a filament dryer box, to prevent moisture absorption. Handle filament with care, and avoid bending, twisting, or tangling the filament. Use a filament holder or guide to ensure smooth and consistent feeding of the filament into the 3D printer.
Calibrate and optimize your 3D printer settings: Calibrate and optimize your 3D printer settings, such as the nozzle temperature, bed temperature, print speed, retraction, cooling, etc., according to the type and characteristics of the filament. Use a temperature tower, a calibration cube, or a test print to find the optimal settings for your filament. Adjust the settings as needed, depending on the ambient temperature, humidity, and other factors that may affect the 3D printing process.
