Abstract:
A hand-held three-dimensional drawing device can include an anti-rotation mechanism that can restrict rotation of a filament moving through the device. The anti-rotation mechanism can have a filament-engaging component in a passage of the anti-rotation mechanism and positioned to engage and restrict rotation a filament extending through the passage. The drawing device can also include a moveable member to control an operation of the drawing device. The moveable member can include a rotatable control mechanism including a portion of an outer profile of a housing of the device. Finally, the drawing device can also include a cover member comprising a portion of an outer profile of housing of the device and positioned adjacent to an actuator to control an operation of the device.
Abstract:
An extrusion device includes a filament-engaging mechanism that urges a filament, received by the device, through a heater and a nozzle. A moveable control member can be manipulated by a user during operation of the device to alter a rate of extrusion. The extrusion device can have a continuous flow mode of operation. The extrusion device can be configured to operate with low electrical power consumption.
Abstract:
A candle conversion device is provided that can allow for complete melting and conversion of candle wax to produce a new wax object or candle. The device can include a thermal sleeve couplable with a candle support having a candle engagement member and a drainage passage, which can direct melted wax toward a wax mold having an inner wax cavity with a shape profile to which the melted wax conforms, the thermal sleeve and the candle support configured to conduct and/or radiate thermal energy received from the candle flame between portions of the device and candle.
Abstract:
An extrusion device can include a driver operatively coupled with a motor such that the driver is rotated about an axis by operation of the motor. The driver can have a passage positioned such that the axis extends through the passage. The driver can have a filament-engaging member positioned in the passage and configured to engage a filament extending through the passage such that rotation of the driver moves the filament relative to the driver. The driver can be positioned such that a first direction of rotation of the driver urges the filament along the axis toward an outlet. A heater can be configured to melt the filament and can be disposed between the driver and the outlet to receive the filament from the driver.
