How many types of 3D printer filament ?



The 3D printers commonly used in the market are well-baked with ABS and PLA materials. So which material is better for ABS than PLA? This is a question that many 3D printing enthusiasts who are just getting started often ask, and the answer lies in understanding the differences in the characteristics of the two materials and understanding which products are more suitable for what kind of application.


ABS-3D printer consumables are the main core of household fused deposition (FDM) wire.

The printing temperature of this material is 210 to 240 ° C, and the temperature of the heating plate is 80 ° C or higher. The printing temperature of this material is 210 to 240 ° C, and the temperature of the heating plate is 80 ° C or higher. The glass transition temperature of ABS (the temperature at which this plastic begins to soften) is 105 °C. In terms of the nature of the material, ABS plastic is fairly easy to print from a hot end point of view. No matter what kind of extruder is used, the material will be smoothly extruded without fear of clogging or solidification. ABS is full of elasticity and is suitable for wearing products. As long as it is printed at an appropriate temperature and the layer material is firmly adhered, the strength of ABS will become quite high. ABS is soft and will only bend and will not break even under pressure. However, this material has the property of being cold-shrinked and will be partially detached from the heating plate and suspended, causing problems. In addition, if the printed object is very tall, sometimes the entire layer is peeled off. Therefore, ABS printing must not have fewer heating plates. In addition, it is recommended that you use a closed printer, at least not in a room where the room temperature is too low, causing the material to cool and cause shrinkage. Not applicable: The disadvantage of this material is that printers without a heater board cannot print. If you want to print large objects without the windshield and temperature-resistant equipment, you must be careful not to let the entire layer peel off and break. In addition, it is best not to use ABS when the room is poorly ventilated, because the smell will make people feel uncomfortable.

  

PLA-3D printer consumables, which are biodegradable plastics, smell like candy when printed.

This material has a printing temperature of 180 to 200 ° C. Although the heating plate is not a must, it is recommended that you use this device at 60 ° C. The real fun of the PLA is the time to put it on the printboard. This material hardly shrinks, and even an open printer can print huge objects without worrying that the finished product is suspended, skewed or broken from the board. This material is suitable for 3D printing in public places on the ground. This material also has a pleasant smell. In terms of printing performance, PLA is almost the opposite of ABS, which often blocks the hot end, especially for all-metal hot ends. This is because the PLA is easily attached and stretched after melting. But this does not mean that PLA is not suitable for printing. As long as the bearing is installed, a drop of oil is applied to the hot end, which can be smoothed and not blocked, and printed in a sweet aroma for a long time. PLA is a biodegradable plastic that can be recycled and decayed, making it suitable for making boxes, gifts, models and prototype parts. PLA is said to be biodegradable, but it will not decompose without heating and has water resistance.

  

The following are the characteristics of common 3D printer consumables.

HIPS features:

1. Excellent comprehensive performance: HIPS has excellent comprehensive performance, excellent dimensional stability and toughness, good forming and machining, and low shrinkage. It does not warp and crack large-scale parts, and the printing effect is smooth. It is also fine, and it can also be used as a supporting material for printing consumables such as ABS, PLA, PA, etc. in double nozzle printing, and it is soluble in limonene solution. The printing temperature is 220-260 °C.

2, chemical stability: impact resistance, oil resistance, water resistance, electrical insulation is good, can be painted later. Good electrical insulation, good toughness and impact resistance. Oil resistant, water resistant and tough, and impact resistant. Oil resistant, water resistant and tough, and impact resistant. Oil resistant, water resistant and tough, and impact resistant. Oil and water resistance 3. Appearance: It has high strength, low weight, smooth and delicate characteristics;

4, application areas: Widely used in handicrafts, architectural models, industrial machinery plastic parts, model machinery, electronic appliances, instrumentation and other industrial fields, is a very versatile thermoplastic engineering plastics.

  

PA features:

1. Excellent comprehensive performance: high mechanical strength, good toughness, smooth surface, small friction coefficient, excellent self-lubricating property, excellent electrical performance and electrical insulation performance, printing temperature 230-280 °C.

2. Chemically stable: good corrosion resistance and strong water absorption.

3. Appearance: high strength and good toughness;

4. Application: Widely used in industrial fields such as mechanical concave wheel, sliding mechanism and bearing
