Introduction
Background
Desktop 3D printers are getting big and bigger. 3D prints follow up. But big usually comes with slow. While there is a rush to find new ways to print faster, there are also many limitations imposed by mechanics, data processing and thermodynamics. Better kinematics, faster mainboards, and higher melt capacity hotends have been at the core of latest improvements.
An acknowledgement of Carl Beck and his 2016’s 3DSolex’s Core Heating nozzles impact on melt capacity led to an improvement and optimization of this technology and the development of the Bondtech CHT® Core Heating Technology that is a main subject of this study in what regards to an alternative inlet geometry of the nozzles.
Problem Description
How to raise the limits imposed by thermodynamics on the hotend’s melt capacity?
This study turns to a specific element of the equation, the nozzle, to find out what is the amount of its influence on the melt capacity of a hotend, and focus especially on the size, the temperature and the inlet geometry of the nozzle.
Purpose
To find out how much the orifice diameter, the temperature and the optimized inlet geometry of the nozzle impact the limits imposed by thermodynamics on the melt capacity of a hotend.
