¶ Interpretation of Common Material Performance Parameters
1. Heat Distortion Temperature
When testing a material (e.g., ABS plastic) under ISO 75 standards, the temperature at which the material begins to deform under different pressures (1.80 MPa and 0.45 MPa) is measured. 1.80 MPa is a higher pressure, typically causing the material to deform at a lower temperature, while 0.45 MPa is a lower pressure, requiring a higher temperature for deformation. This value is used to assess a material’s resistance to deformation under high temperatures and pressures.
2. Saturated Moisture Absorption Rate
This refers to how much water the material can absorb in a humid environment. It indicates the material’s ability to absorb moisture, usually expressed as a percentage. Materials that absorb more water may become soft, swollen, or deformed, and even affect their strength and durability. Knowing this value helps in choosing the appropriate material to avoid performance degradation due to moisture absorption.
3. Tensile Break Strength
This is the maximum tensile force the material can withstand before it breaks when stretched. In simple terms, it refers to “how much force the material can handle before it breaks when pulled.”
4. Elongation at Break
This refers to the percentage change in length of the material when stretched to the point of breaking. In other words, “how much the material can stretch before it breaks.” A higher value indicates that the material is more ductile and can stretch further without breaking.
5. Young’s Modulus
Young’s modulus measures the stiffness of a material and describes the degree to which the material deforms under stress. It can be understood as “material hardness.” The higher the value, the less the material deforms and the harder it is.
6. Flexural Strength
This is the maximum force the material can withstand when bent. In simple terms, it refers to “the maximum force the material can bear before it breaks when bent.” A higher value means the material is better able to withstand bending without breaking.
7. Flexural Modulus
This measures the stiffness of the material when subjected to bending forces. It describes the material’s resistance to deformation when bent. A higher value means the material is harder to bend and less likely to deform under bending.
8. Notched Impact Strength
This refers to the maximum force the material can withstand when subjected to an external impact, particularly at a notch or defect. Notches may make the material more prone to breaking, so a higher value indicates better impact resistance, especially at notched locations.
9. Tensile Modulus
This refers to the stiffness of the material when stretched, or its resistance to deformation when subjected to tensile forces. A higher value indicates that the material is harder and less likely to elongate, meaning it is stiffer and less prone to deformation.
¶ Health Tips — Caring for Your Health: FusRock Recommends You
1. For long-term and extensive use of 3D printing materials, it is recommended to operate in a dedicated room with proper ventilation.
2. If you have a history of allergies, make sure that the material you are using will not cause any allergic reactions upon contact.
3. For individuals with respiratory conditions or chronic illnesses, please wear a mask to protect your health. Even if you do not have any related conditions, it is strongly recommended to wear a mask during operation.
4. When sanding, cutting, or performing other actions on fiber-based printed products, which may release fibers, be sure to take protective measures to prevent injury or inhalation.
5. Lastly, we recommend keeping children and infants away from the printing area during operations to ensure a safe environment for the next generation.
