초록 ▼

An apparatus to receive a filament material and to move the filament while guiding a direction of movement of the filament comprising: a metal block that defines a first guide passage sized to receive the filament;wherein the block includes a first plate that includes a first surface that defines a first groove and includes a second plate that includes a second surface that defines a second groove; andwherein the first and second faces of the first and second plates are in abutting contact with the first and second grooves aligned to define the first guide passage;a drive mechanism configured to move the filament into the first guide passage.

대표청구항 ▼

1. An extrusion head to receive a solid state material in filament form and to move the filament while guiding a direction of movement of the filament and to output the material in molten form comprising: a high thermal conductivity metal block that defines a first guide passage sized to receive the filament and that includes a first opening and a second opening and that defines a recessed region adjacent to the second opening;wherein the block includes a first plate that includes a first surface that defines a first groove and includes a second plate that includes a second surface that defines a second groove and a first portion of the recessed region; andwherein the first and second surfaces of the first and second plates are in abutting contact with the first and second grooves aligned to define the first guide passage and a second portion of the recessed region;a drive mechanism configured to move the filament into the first guide passage through the first opening and out from the first guide passage through the second opening;a low thermal conductivity housing defining an inner tube section providing a passage through the housing between a first end portion of the housing and a second end portion of the housing, wherein an outer surface of the first end portion of the housing is configured to snugly interfit with the recessed region of the block, and wherein the inner tube is aligned with the second opening of the first guide passage;a high thermal conductivity pipe disposed within the inner tube section of the housing and defining at least a portion of a second guide passage that is aligned with the second opening of the first guide passage and that includes a first end portion and a second end portion, wherein the first end portion of the pipe is closer to the second opening of the first passage and to the first end portion of the housing than is the second end portion of the pipe, and wherein the first end portion of the pipe is sized to receive the filament; anda heating element configured to heat the second end portion of the pipe to convert the filament received at the first end portion of the pipe to molten form at the second end portion of the pipe. 2. The extrusion head of claim 1 further including: a releasable fastener configured to secure the first and second plates with the housing between them. 3. The extrusion head of claim 1 further including: a screw securing the first and second plates with the housing between them. 4. The extrusion head of claim 1, wherein the first opening is tapered to be wider closer to where the filament enters the first opening. 5. The extrusion head of claim 1, wherein the drive mechanism includes a driver roller and an idler roller disposed to move the filament received them though the first and second passages. 6. The extrusion head of claim 5 further including: a fulcrum block;a lever rotatable mounted to the fulcrum block;wherein the idler roller is rotatably mounted to the lever; anda spring disposed to provide forces to the fulcrum block and the lever that urge the idler roller towards the drive roller. 7. The extrusion head of claim 6, wherein the spring includes a lever spring coil. 8. The extrusion head of claim 6 further including: a platform;wherein the block is mounted to the platform;wherein the drive mechanism is mounted to the platform; and further including:a motor mounted to the platform and disposed to actuate the drive mechanism. 9. The extrusion head of claim 1, a heat insulating material disposed within the inner tube section of the housing between the first end portion of the pipe and the second opening of the first passage. 10. The extrusion head of claim 1 further including: a motor disposed to actuate the drive mechanism.
