Embodiment Construction

[0032] figure 1 Extruder 100 is shown including extruder cover 104 , filament guide 108 , filament inlet 112 and blower 120 . Filament 116 is shown secured within filament guide 108 and enters extruder 100 through filament inlet 112 . The filament guide 108 is integrated or molded into part of the extruder cover 104 and guides the filament 116 into the filament inlet 112 . The blower 120 is installed on one side of the extruder 100 .

[0033] Figure 2A show figure 1 A cross-sectional view of the extruder 100, wherein the filament 116 is shown secured in the filament guide 108 and enters the extruder 100 through the filament inlet 112. exist Figure 2A100, extruder 100 is shown without the extruder cover, showing circuitry connected to ribbon cable 128, feed tube 132, heat sink 136, outlet 140, thermal guard 144, and multiple servo motors 148, 152 System 124. In contrast to temperature control systems that use more than one blower, the illustrated embodiment uses only o...

Abstract

A temperature control system for an extruder (100) of a 3‑D printer comprises a blower (120) and a baffle system, using the same blower by directing the air flow of the blower to the air flow arranged at the outlet of the blower Two channels (172, 180) to cool the different parts of the extruder.

Description

technical field [0001] The present invention relates generally to temperature control systems for extruders of three-dimensional ("3-D") printers, and more particularly, to temperature control capable of controlling the temperature of multiple components of an extruder using a single cooling fan or blower System configuration. Background technique [0002] 3-D printing, or additive manufacturing, is the process of making three-dimensional solid objects based on blueprints provided by digital files. Composition of the desired 3-D solid object is achieved by strategically generating successive layers of added material in a pattern on the platform of the 3-D printer until the entire object is created. The composition of 3-D objects is driven by digital files that provide specifications describing how the layers are created and the materials used to generate the objects. Digital files specifying designs are provided by the user, and examples of digital files read by a 3-D prin...
