How to Prevent Warping: Tips for Better Print Adhesion

Warping is a common issue in 3D printing, where the edges of a print curl up and detach from the build plate, leading to inconsistent prints and failed models. This happens because the material cools and contracts unevenly, causing layers to deform and lift. You can spot warping by looking for edges that peel up from the bed during printing.

But don’t worry, there are several effective ways to prevent warping and improve your print success rate. Let’s dive into the best solutions to keep your prints flat, strong, and securely adhered to the bed.

1️⃣  Use a Heated Bed

A heated bed keeps the lower layers of a print warm throughout the process, thereby reducing temperature fluctuations that cause shrinkage. Here are some standard bed temperature recommendations for different materials:

• ABS: 80°C – 100°C
• PLA: 50°C – 60°C
• PETG: 70°C – 80°C

For materials prone to warping, a consistently heated bed temperature can make all the difference!

2️⃣  Disable Cooling

Cooling fans can cause the first few layers to contract too quickly, increasing the risk of warping. If necessary, use an enclosed printer which helps maintain a stable warm environment to reduce cooling inconsistencies.

3️⃣  Apply an Adhesive

Using adhesives such as hairspray, glue sticks, or dedicated 3D printing adhesives on the build plate can create a strong first-layer adhesion, which helps prints stay firmly in place. Ensure the adhesive is evenly applied for best results and make sure to clean your bed before applying a new layer of adhesive!

4️⃣  Use a Brim or Raft

Adding a brim or raft in your print settings increases the surface area of the first layer, improving adhesion:

• Brim - Adds several single-layer rings around your object and creates a thin outline around the model for better grip.
• Raft - Lays down a thick grid base layer underneath the print for maximum stability.

These settings are especially useful for large, flat prints that are prone to lifting.

Warping can be frustrating, but with the right settings and preparation, you can significantly reduce print failures. Whether it’s adjusting the bed temperature, improving first-layer adhesion, or using a brim or raft, these small changes can lead to big improvements in print quality.
