We have replaced aluminum with high-density graphite in our build plate design, addressing common material issues and
enhancing long-term usability. The key advantage of graphite is its low thermal expansion, allowing it to maintaining low
deformation rates at high temperature. Additionally, its high thermal conductivity reduces resistance between the heater
and steel sheet, leading to faster and more stable heating. These features improve both performance and durability, making
graphite a superior choice for FDM 3D printers.
The thermal expansion coefficient is much lower than aluminum build plate.
The heating speed is faster than aluminum
build plate.
The uniqueness of the graphite build plate lies in the thermal expansion characteristics of graphite. When a materialor substance is heated, it expands and deforms. However, graphite has a very low thermal expansion coefficient and not easily deformed even heating up to 100 degrees for a long time.
Benefit from the high thermal conductivity of the graphite. This effectively reduces the thermal resistance between the silicone heater and the spring steel sheet, making the heating process faster and more stable.
Our team has encountered significant hurdles in manufacturing high quality graphite plates for 3D printiers.
The graphite particles generated during grinding cause rapid wear on cutting tools, necessitating frequent replacements. Meeting our strict standards for product flatness requires changing to a new set of tools for each plate.
Flat build plate essential for uniform adhesion. Uneven plate leads to thickness variations, poor adhesion. Risk of warping or detachment, affecting accuracy. we have established a minimum flatness requirement of +/- 0.05mm.
Reliable high-density graphite build plates: Guaranteed unbreakable under normal usage conditions!
High-density graphite excels in thermal stability, with a low expansion rate that ensures minimal size changes in fluctuating temperatures. It withstands significant thermal expansion without deforming, even when exposed to 100°C, maintaining low deformation rates despite the use of magnetic tiles and PEI sheets.
High-density graphite's layered structure provides excellent thermal conductivity in all directions, allowing efficient heat dissipation. In contrast, aluminum alloys may exhibit suboptimal conductivity due to their crystal structure. Graphite’s superior thermal performance and high-temperature resistance make it advantageous for thermal applications.
