Frequently Asked Questions

Q: What is GD900 thermal paste and what is it used for in 3D printing?

A: GD900 is a silicone-based thermal compound with a thermal conductivity of 4.8 W/M-K. It is applied to 3D printer hotend assemblies — particularly throat tubes and heat sink interfaces — to improve heat transfer, maintain stable operating temperatures, and prevent heat creep during extended print sessions.

Q: How do I apply GD900 thermal paste to my 3D printer hotend?

A: Clean the contact surfaces of the hotend throat tube and heat sink. Apply a small, even amount of GD900 paste directly to the surface using a fingertip, plastic card, or spatula. Reassemble the hotend and allow the printer to run a short warm-up cycle to help the compound settle. No special tools are required.

Q: Is GD900 thermal paste compatible with all 3D printer brands?

A: Yes. GD900 is a universal thermal compound that works across a wide range of FDM 3D printer brands and hotend models. Its broad operating temperature range (-50°C to 200°C) means it is suitable for standard PLA setups as well as high-temperature engineering material printers.

Q: How long does the GD900 thermal compound last before needing reapplication?

A: Thanks to its silicone-based, non-drying formula, GD900 is designed for long-term use without hardening or degrading. Under normal 3D printing conditions, a single application can last for an extended period, even in continuous-use workshop environments.
