Description
Technical field
The present invention relates to 3D printer apparatus fields, relate in particular to a kind of 3D foldings printer.
Background technology
There are many similar 3D printers currently on the market.The feature of these printers is nearly identical, and market
On the printer arrangement form sold be broadly divided into three categories：1.makerbot types；2. cross XYZ types；3. flame.These set
Standby is all by carrying out slicing treatment in the Z-axis direction to threedimensional model, obtaining the cutter track track of every layer cross section profile.Then
Gcode language is decoded by printing mainboard, the principle of three-shaft linkage is all based on using structure, by tri- axis of X, Y, Z
Gearing command be transferred to the motor of each axis, to control the movement of motor.The rotary motion of motor is transmitted further to the whole of printer
A transmission system.
Traditional 3D printer transmission is driven by rubber synchronous belt and synchronizing wheel and stepper motor.Such transmission
Precision it is poor, therefore be mainly used for printer model, and be not used to industry, mainly by following several reasons：
1. the time-write interval is longer, synchronous belt generates friction meeting expanded by heating with synchronizing wheel, causes tooth form to deform, synchronous belt becomes
Long, tooth gaps become larger, and step, wrong step phenomenon are lost in generation, so that driving error increases；
2. synchronous belt material is mostly rubber, elasticity is larger, and carrying out tooth form with synchronizing wheel engages, and tooth gaps are big, and tooth is more
For zigzag, when transmission, is vibrated larger；
3. most printers manufacturer uses low-power stepper motor on the market.Low-power stepper motor is with printing speed
The increase of degree, torque reduce, and almost 0, can not accurately driving force be provided for transmission system.And such stepper motor is mostly to open
Ring controls, and can not adapt in print procedure quickly to accelerate and the case where quick deceleration, it is easy to which generation loses step, wrong walks phenomenon；
4. the existing big multi-in-line of printer is relatively rough, mostly bareing winding displacement, interference is susceptible in print procedure
Workbench, or even directly broken by movable parts such as workbench.In addition, exposed winding displacement be easy to cause the oxidation of winding displacement for a long time,
Electrostatic interference etc., and exposed winding displacement reduces the aesthetic feeling of the design of equipment.
5. the low space utilization of most of printers, entire fuselage is mostly one big machine box composition, very heavy, no
It is easy to remove.
