How to avoid deformations in your 3D prints?

In the manufacture of parts and 3D printed prototypes, part deformation is one of the major issues that can arise during the process.  

In this article, we tell you everything you need to know about the deformation of 3D printed parts. Additionally, you will also find effective strategies and techniques to prevent or correct this error in the 3D printing process.  

What is warping?

The term warping can be translated into Spanish as warping or bending, therefore, it is the term used when the first layer of a part deforms and detaches from the print surface.  

Deformation typically occurs in large or long parts, as it is in this type of parts where thermal stresses in the part become more intense and eventually cause the corners to detach.  

What are the causes of deformation in 3D printing?

Deformation of the 3D printed parts is a common problem in this technology, and it can be caused by several factors. Some of the most common causes are: 

• Base leveling: if the base is not level, the probability of the print deforming as the plastic cools is higher. 
• Bed temperature: if the bed is too cold, it can cause the plastic to cool too quickly and, therefore, deform. 
• Print geometry: parts with complex geometries are normally more prone to deforming, as they have more contact points with the bed, that is, more areas prone to cooling and shrinking. 
• Print material: it is important to keep in mind that there are some materials that are more prone to deforming than others (for example, ABS). 

Solutions for deformation in 3D prints

As we have mentioned, although deformation in the 3D printed parts can be a serious problem in the 3D printing process, there are ways to prevent it and solve it. Below, we present some examples: 

Temperature regulation 

One way to avoid deformation is to regulate the temperature of both the printer and its surroundings. For this, there are several methods: 

First, it is possible to adjust the cooling, as most 3D printers currently have a part cooling fan that helps cool the material while printing. It is essential to adjust both the speed and direction of the fan to help control the rate at which the material cools.  

Another simple way to regulate temperature is by using a heated build plate. This prevents the material from cooling and contracting too quickly. At this point, it is important to note that to use a heated build plate, you must have a printer with a base capable of heating.   

The cutter configuration 

Another optimal solution to prevent warping in 3D printed parts is to print more slowly, as this gives the material more time to cool and solidify before adding the next layer. This is a technique especially useful for materials prone to warping.  

For this, only the print speed settings in the 3D printer software need to be adjusted. 

Still, it is important to keep in mind that the optimal speed will depend on the material used and the complexity of the printed part.   

Bed adhesion 

Bed adhesion is a key aspect to prevent warping during the 3D printing process. Using an appropriate adhesive will help ensure the part remains adhered while cooling and, therefore, reduce potential warping issues. 

Edge addition 

If, after testing all the previous options, your parts continue to warp or deform, another possible solution is to add a border to your prints. This will help keep the part edges adhered, as they generally have only a few layers in height.
