Choosing the right print bed surface can dramatically improve your 3D printing success. FR4 and G10 are popular contenders, both being fiberglass epoxy laminates, but with key differences.
FR4 is generally more affordable and offers good adhesion for many materials like PLA and PETG when heated. However, it can be more prone to warping, especially with larger prints or materials requiring higher bed temperatures.
G10, on the other hand, boasts superior strength and temperature resistance. This makes it less susceptible to warping and a better choice for demanding materials like ABS or nylon. Its enhanced durability also translates to a longer lifespan.
Ultimately, the best choice depends on your printing needs and budget. If you're primarily printing with PLA or PETG and looking for a cost-effective option, FR4 is a solid choice. But if you frequently print with temperature-sensitive materials or prioritize durability, G10 is worth the investment for its enhanced performance and longevity.
