How to choose an extruder for a 3D printer
3DPrintStory 3D printing process How to choose an extruder for a 3D printer
Hello friends.
Today we will talk about choosing an extruder.
In simple terms, an extruder is a mechanism whose task is to feed molten plastic into the printing zone. It consists of a feeding mechanism and a print head.
Two types of extruders
There are two main types of extruders: bowden (bowden) - in the picture on the left and direct (direct) extruder - in the picture on the right. With a direct extruder, the plastic feed mechanism is located in close proximity to the print head. In bowden - at some distance, connected by a Teflon tube. nine0003
The main advantages and disadvantages of the two types of extruders
Both have their advantages and disadvantages.
In direct extruders, the weight of the stepper motor with the plastic feed mechanism is added to the weight of the printhead. Excess weight will increase the inertial forces when stopping and accelerating the print heads, which can adversely affect the quality of 3D printing, especially at high speeds, and also causes increased wear of the kinematics of the shafts and bearings.
But the supply and rollback of plastic (the so-called retract) is more accurate, which makes tuning easier. nine0003
Bowden eliminates the disadvantages of direct extruders regarding extra weight, since only the print head runs along the carriage, which makes it possible to print at higher speeds. But in return, we get problems with the exact dosage of plastic, which will complicate tuning and calibration.
Extruder design
All extruders are similar in design and differ only in execution. Let's look at what the extruder consists of using the well-known e3dv6 model as an example.
These are three main nodes: cold end (cold part), hot end (hot part), which are connected by a thermal barrier. nine0003
Hot end consisting of:
- Heating element to melt plastic.
- Measuring element (thermistor) for maintaining the desired temperature.
- Aluminum heating block to house them.
- Nozzle with calibration hole from 0.1 to 0.8 millimeters.
Cold end is:
- Aluminum heatsink with fan, which serves to cool the plastic, preventing it from melting prematurely. nine0056
- Thermal barrier that serves to isolate these two elements from each other. Usually it is a stainless steel sleeve, and sometimes plain steel. Stainless steel is still preferable, since it is no worse than ordinary steel in thermal conductivity. By the way, when buying, pay attention to this! Easy to check with a magnet. With a relatively similar weight, stainless steel is not magnetic. The nozzle, on the contrary, should be made of a material that conducts heat well.
Detailed construction and features of the e3dv6 extruder
In our case, we will consider a bowden extruder based on a Chinese copy of e3dv6.
The Chinese copy works as well as the original, but costs several times cheaper. The difference is only in the quality of processing and the materials used. Please note that there is also an older version of e3dv5.
They are very similar in appearance, but still have significant differences. I do not recommend taking e3dv5, since e3 dv6 is an improved version of it. The e3dv5 has a larger heatsink and a slightly different heating block. In e3dv6, the thermistor is placed closer to the nozzle than to the heater relative to e3dv5, which provides more accurate control and maintenance of temperature in the area of \u200b\u200bthe plastic, and not the heater. nine0003
There are versions for different plastic diameters. 1.75 millimeters, which most print or 3 millimeters.
To avoid traffic jams, choose a thermal barrier with a Teflon tube insert for PLA printing. It is smoother and slipperier.
Solid metal is more suitable for printing with nylon, ABS or other plastics that require a higher printing temperature, since the Teflon tube in the middle is already destroyed at a temperature of about 200 degrees. On the Internet they write that the all-metal barrier in the original prints with all types of plastic, since the hole in the middle is well polished and smooth, unlike the Chinese counterpart, in which the hole was drilled with a conventional drill without additional post-processing.
