Recently, the leading manufacturers presented special printers, printing parts, shapes and various elements in 3D. This type of equipment is very difficult to design, and the characteristics of its work correspond to the latest advances in high technology. In order to properly maintain the equipment, you need to understand the principle of its operation and internal design.
For normal printing, just read the instructions and manual for the device. It describes a detailed action plan for turning on and pairing with a computer. But sometimes when working, various malfunctions can occur, the solution of which may require serious repairs. Today we’ll talk about one of the common problems in printing 3D parts. We are talking about poor adhesion of material to the printer table. This problem prevents the creation of parts and disrupts the operation of the entire device.

In order to print, you need a special polymer material. To work on different models of printers, different materials are used. To understand what material you need to use for your equipment, check with specialists or a consultant in the store.
The most common polymers for printing are PLA and ABS, the features of which include the following characteristics:
- made of natural materials - ABS from oil, and PLA from crops and their processed products;
- well give in to processing and can take the most various forms and sizes set by the program;
- able to stain and change the degree of transparency of the product;
- strength, while maintaining the plasticity of the parts;
- solubility - allows you to glue parts and smooth the edges of the workpieces.
Also a distinctive feature is the good fusibility of the material. However, the low melting point is a minus and can ruin the quality of the printed part.
ATTENTION! If the first layer of the workpiece spreads or greatly extends beyond the table, in the future the design will also have a bad shape. It is better to immediately stop the work and start again.
What to do if PLA comes off the printer desk
If you encounter a similar problem: during operation, the part does not stick to the surface of the table, you should try to do the following:
- Adjust the temperature supplied from the nozzle. With strong heating, the lower layers can melt, which harms the entire structure.
- Set the minimum allowable distance from the table to the printing press. The height should not be less than the diameter of the nozzle.
- Calibrate and adjust the print head for the first layer. If the part does not attach to the table, change the pressure force and the amount of feed to the lower layers.
- Pick up and replace the table. It is better to choose a material with good adhesion (adhesion): cardboard, beer, plexiglass.
- Try to print the first levels solid to create a special substrate on which the future part will be mounted. At the end of the work, you can gently remove the lower layers and edges.
- Make sure that the workpiece does not go beyond the working field. Reduce the size of the shape or expand the field.
If there is no effect, you can change the system settings when printing. But, most likely, you will have to contact the master for the repair of equipment. Describe the problem, use the warranty for free diagnostics and troubleshooting.
