Testing the printer before 3D printing

To better enhance the finished 3D printed model, never print blindly and in a hurry. Be sure to do all aspects of checking before printing, including the 3D printer and filament materials, to ensure the print quality and proper operation of the setup.UJOYBIO3D has summarized the following for all 3D printing enthusiasts on the checking of the printer and filament respectively:

Inspection of the 3D printer

1. Hardware check of the printer

First, check whether the printer frame structure is stable, and see whether the screws and connectors of the printer structural parts are loose. Make sure the printer platform is level and firmly fixed. If the printer has a leveling function, the printer must be leveled first. Some printers come with special leveling tools or calibration cards that can help you level the platform more accurately.

For printers with extruders or nozzles, check that the nozzles are not clogged and look for residual consumables in the nozzles. Make sure the extruder gears are clean and running smoothly, and that the nozzles are not clogged.

For the printer's drive system, check for wear and tear or slack in belts, slides, bearings, etc., which must be adjusted and lubricated when it affects normal printing.

2. Printing software check

For the printer software, if the current printing software has been adequately matched to the printer, it is not necessary to update to the latest version, the most important thing between the printing software and the printer is compatibility.

And in the slicing software, you need to check whether the printing parameters are in line with the model and material requirements, such as layer height, printing speed, temperature, filling and support.

In general, the layer height is 0.2mm by default, but in order to have a better effect on the finished model, you can set the layer height to 0.12mm, so that the surface of the finished model printed will be more delicate and smooth.

Commonly used printer nozzle diameter of 0.4mm, but if the layer height of the print is less than 0.2mm, can not check the model to update the detailed information, this time you need to strong generator to select the “Archne” in order to preview the details of the model effect.

3. Printer environment

For closed printers, you need to pay attention to the internal temperature of the printer ventilation and heat dissipation, if the nozzle because of high temperature conditions, affecting the heat dissipation, it is easy to cause the printing process to produce pull or string phenomenon.

For open printers, to maintain a stable printing environment, to avoid excessive dust or airflow interference, affecting the quality of the model after cooling, resulting in the model surface is not smooth, as well as the adhesion between the layers and layers of the problem.

4. Power and Security

The stability of the power supply is a very important logistical support for 3D printing, check whether the line is damaged before printing. Avoid emergency interruptions during the printing process, you can first test the emergency stop button or power failure recovery function is normal.

Make sure there are no obstacles in the printer area to avoid unnecessary accidents during printing.

5. Preparation before printing

Do a preliminary preview of the model file to check if the slice file is correct and make sure there are no obvious defects or problems.

If the printer's platform adhesion is insufficient, it may be necessary to apply an appropriate amount of adhesive on the printing platform, such as using part of the glue or special film, which can prevent the model warping.

However, it should be noted that the vast majority of printers are currently set up in the first layer of printing, will do a widening process, and most of the current filament in the platform force has a certain degree of adsorption, so this situation needs to be for your make appropriate adjustments.

6. Calibration and testing

Most printers have automatic high level function, you can choose “automatic leveling” or “bed leveling” option in the printer menu to start the program. If it is manual, it is a little more complicated, manual leveling has the same effect.

In the case of a filament material recharge, a simple test model or temperature tower can be printed first to check the machine operation and printing results.

Inspection of the printed filament material

Before 3D printing, it is very important to check and handle the printing filament material, which can effectively avoid printing faults and thus improve the quality of the finished printed product.

1. Filament Material Appearance Inspection

When using brand new filament material, first check whether the filament material is sealed with a desiccant and the sealing of the package. After removing the filament, check whether the filament appearance is clean and check whether there is dust, oil or other pollutants on the filament surface, as dirty filament may clog the nozzle.

Ensure that the color of the filament material is uniform and free of color difference, especially in the printing requirements of higher quality models, the color unevenness is very affect the aesthetics, multi-color filament, you need to check the uniformity of color change of the filament.

The current market mainstream filament diameter is 1.75mm, the fluctuation range should be within ± 0.02mm, can be initially viewed through the appearance of the diameter and equipment settings to match the 1.75mm filament is more compatible with the vast majority of the current market FDM printers. Check whether the diameter of the filament is stable, will affect the stability of the filament in the nozzle extrusion.

If the filament material has not been used for a long period of time, the filament needs to be carefully checked for embrittlement or small cracks. Also check that the filament is tightly and neatly wound on the spool to avoid tangles, jams, or kinks during printing.

For used filament materials, make sure that the current filament length is sufficient to complete the entire print job to avoid failures due to intermediate replacement.

2. Filament preservation status

Currently the mainstream thermoplastic materials, such as PLA, ABS, PETG, Nylon and other filament materials are easy to absorb moisture. Printing with moisture may produce bubbles, rough lines or poor inter-layer adhesion.

Therefore, we can check the filament surface for white spots, brittleness or loss of luster. As well as in the printing process, whether there are heard “popping” sound or bubbles appear, there is such a situation of filament, it means that the moisture has been, need to be taken down in time to do the drying process. You can use consumable drying oven or oven, and use low temperature, such as 40-60 ° C for drying.

3. Filament material storage

UJOYBIO3D's filaments are stored in desiccant and sealed.

Filament material is recommended to be stored in a sealed bag, together with the drying box in a sealed storage, conditions permit, you can add a hygrometer, in order to more intuitive view of the filament storage situation.

Avoid humidity, high temperature and direct sunlight in the drying box to avoid oxidization of the filament. And make sure the ends of the filament are well fixed to avoid knots.

4. Pre-loading check

When loading the filament material into the printer, manually feed the filament into the extruder to make sure that the filament can pass through the inlet smoothly, and the whole process to make sure that there is no obstruction, so as not to cause the subsequent printing process out of the more poor feeding situation.

In order to have a better printing experience, you can print before the start of a small test model, UJOYBIO3D recommended here to print the temperature tower, which can reflect the effect of filament printing, but also to find the best filament printing temperature, but also can be observed out of the nozzle extrusion status is normal.

5. High-speed printing function

If you have a high-speed demand for the current printing, but also need to not affect the quality of the finished product of the printed model, you need to pick a corresponding high-speed filament material with the printer. The mainstream 3D printing filament material on the market is basically maintained at 150-250mm/s. If you need higher speed, do not hesitate to use UJOYBIO3D's Hyper PLA+ series of filament, which supports up to 500mm/s of ultra-fast printing, and the finished product's surface is still very smooth and delicate, with good toughness and impact resistance.

6. Special requirements for filament materials

If you use transparent filament material, you need to pay special attention to the drying situation, after being damp transparent filament, the finished model will appear in the print out of the fogging effect, greatly reducing the model of the printing experience.

If you use high-temperature printing filament, such as nylon, PC and other filaments, you need to ensure that the printer has a closed environment and high-temperature extrusion function, here you can check on the printer.

Summarize

In 3D printing, the quality and preparation of the printing filament, as well as the inspection of the 3D printer before printing, will directly affect the final product.
