Warping on 3D printing——Why&How | iSANMATE

Why is 3D printing warping?

Warping is a common problem for many 3D printing enthusiasts, but don’t worry! Here, I will reveal the reasons behind it and provide some practical ways to solve the warping problem. Let’s solve this mystery together!

Several factors can contribute to filament warping in 3D printing:

1. Material properties: Different materials have varying levels of shrinkage and adhesion to the build plate. Materials with high shrinkage rates, such as ABS, are more prone to warping compared to materials like PLA.
2. Printing temperature: If the printing temperature is too high, it can accelerate the cooling process and increase the likelihood of warping. It is essential to find the optimal temperature for the specific filament being used.
3. Build plate temperature: Insufficient build plate temperature or uneven heating can cause the printed object to cool down at different rates, leading to warping. Using a heated build plate and ensuring it is evenly heated can help minimize warping.
4. Printing speed: Printing too quickly can prevent each layer from fully cooling before the next layer is added, which can contribute to warping. Slowing down the print speed or increasing the cooling time between layers can help reduce warping.
5. Cooling and ventilation: Inadequate cooling or inadequate ventilation in the printing environment can lead to uneven cooling of the printed object, resulting in warping. Ensuring proper cooling fans and a well-ventilated printing area can help minimize warping.
6. Design and geometry: Certain geometries, such as overhangs or tall and thin structures, are more prone to warping due to the uneven distribution of forces during cooling. Consider adding support structures or adjusting the design to minimize warping.

How to prevent 3D printing from warping?

1. Bed leveling: Ensuring that the build plate is properly leveled helps to create an even and consistent first layer, reducing the chances of warping.
2. Build plate temperature: PLA generally adheres well to a heated build plate. Set the build plate temperature to around 60-70°C to improve adhesion and reduce the likelihood of warping.
3. Enclosed build chamber: An enclosed build chamber helps maintain a more constant temperature throughout the printing process, reducing temperature fluctuations that can lead to warping.
4. Raft or brim: Printing with a raft or brim can provide extra support and adhesion to the model, minimizing warping. These features create a wider base for the object, improving stability.
5. Slow cooling: Allow the printed object to cool gradually inside the printer before removing it. This can help minimize warping caused by sudden temperature changes.
6. Printing orientation: Adjusting the orientation of the model can have an impact on warping. Printing flat surfaces parallel to the build plate reduces the stress on the model and can help prevent warping.

By implementing these measures, you can minimize the chances of PLA warping during 3D printing and achieve more successful prints.Other filaments you can adjust according to its specific characteristics.
