Introduction

Copolyesters are formed by modifying polyesters. PETG is a popular copolyester used in 3D printing. On Filaments.directory PETG has its own section listed separately from copolyesters as there are such a wide variety of PETG filaments to choose from. Like PETG, many common copolyesters are based on Terephthalic acid.

The advantage of printing with copolyesters is that they retain many of the desirable properties of the original polyesters whilst being much easier to print. Copolyesters often display excellent chemical and solvent resistance in addition to their strong mechanical properties.

As well as being very durable, colpolyester is available in a wide variety of colours. This makes it an excellent option for use in final products. Colpolyesters also display excellent dimensional stability with very little warp or shrinkage, making them a great option for printing prototypes.

Copolyesters tend to have a much better temperature resistance than PLA, usually between 75°C and 110°C. They also have good melt strength, meaning they can bridge across parts quite well without breaking.

Copolyesters can be easily post-processed. They will stand up well to drilling, filing and cutting.

Copolyesters are great options for applications that need heat resistance, durability, chemical resistance and impact resistance. Here at Filaments.directory you can select the right copolyester filament using our constantly updated list of suppliers and our comprehensive search tool!
