Chinese factories to eliminate 3D printing problems

Search and elimination of 3D printing problems onChinese factories to eliminate 3D printing problemsIt can be a difficult task that requires a deep understanding of both the 3D printing process and the specifics of a particular equipment. An effective solution to problems includes a systematic approach, from the diagnosis of the main causes of defects to the use of corrective measures. This article discusses the common problems of 3D printing and methods for their solutions used in Chinese factories to ensure high quality products.

Common problems of 3D printing and their causes

3D printing, like any production process, is subject to various problems. Understanding these problems and their main reasons is the first step to an effective solution.

Problems with adhesion of the first layer

Poor adhesion of the first layer is one of the most common problems. If the first layer does not stick to the platform, the subsequent layers will also be printed incorrectly.

• Reasons:The improper height of the nozzle, an insufficiently heated platform, a contaminated platform, the inappropriate platform material.
• Solutions:Adjust the height of the nozzle, increase the temperature of the platform, clean the platform with alcohol or acetone, use the appropriate platform material (for example, blue tape, adhesive-pencil).

Deformation (Warpping)

Deformation occurs when the printing angles rise from the platform during printing.

• Reasons:The difference in temperature between the layers is not a heated platform, drafts in the room.
• Solutions:Increase the temperature of the platform, use the closed print chamber to maintain a constant temperature, apply glue to the platform to improve adhesion.

DELAMINATION (DELAMINATION)

Sliding is the separation of the layers of the imprint during printing.

• Reasons:Insufficient nozzle temperature, insufficient cooling, low print speed, weak adhesion between layers.
• Solutions:Increase the temperature of the nozzle, reduce the cooling rate, increase the print speed, make sure that the right material is used.

Support problems

Support is necessary for printing overhanging parts of the model, but they can cause problems if they are incorrectly designed or removed.

• Reasons:Incorrect geometry of support, too strong clutch with the model, fragile material of support.
• Solutions:Use the correct geometry of support (for example, tree support), reduce the density of supports, use material that is easily deleted.

Clotting of the nozzle

The clogging of the nozzle leads to uneven feeding of the material or a complete stop of printing.

• Reasons:Contaminated material, incorrect nozzle temperature, too slow print speed.
• Solutions:Use clean material, check and adjust the nozzle temperature, increase print speed, use special tool cleaning tools.

Displacement of layers

The displacement of the layers occurs when one or more layers move relative to others, which leads to defects in geometry.

• Reasons:Weak belts tension, improper calibration, printer vibration, problems with engines drivers.
• Solutions:Check and pull the belts, calibrate the printer correctly, install the printer on a stable surface, update or replace the engine drivers.

Methods for eliminating problems in Chinese factories

Chinese factories to eliminate 3D printing problems, as a rule, have well -organized processes of elimination of problems that include:

Diagnostics

The first step is the exact diagnosis of the problem. This includes a visual inspection of the print, checking the printer settings and analysis of the log files.

Using diagnostic tools

In factories, specialized tools are often used to identify problems, such as:

• Visual control cameras:To detect surface defects and internal defects.
• Temperature sensors:To check the temperature of the nozzle and platform.
• Vibration sensors:To identify vibration, which can cause displacement of layers.

Data analysis

The collected data is analyzed to determine the main reasons for the problem. This process can include:

• Comparison with reference prints:Comparison of a problem imprint with a print made under perfect conditions.
• Statistical analysis:Analysis of data on temperature, speed and other parameters for identifying anomalies.

Corrective actions

After determining the cause of the problem, corrective actions are used. This may include:

• Printer settings change:Optimization of temperature, speed and other print parameters.
• Replacing components:Replacing damaged or worn out printer components, such as nozzles, heaters and engines.
• Changing the material:The use of another material that is more suitable for a specific task.

Tips for preventing 3D printing problems

Prevention of problems is the best solution. The following tips will help reduce the likelihood of problems in 3D printing:

• Use quality materials:Cheap or low -quality materials may contain pollution that cause clogging of the nozzle and other problems.
• Serv the printer regularly:Clean and lubricate the moving parts of the printer, check the belt tension and calibrate the printer.
• Correctly store the materials:Keep the materials in a dry place to avoid moisture absorption.
• Check the print settings:Make sure that the print settings correspond to the material used and the desired quality of the print.
• Spend test prints:Before the seal of complex models, it is recommended to draw a test imprint to make sure that everything works correctly.
