Abstract: A 3-axis parallel linear robot has three drivers disposed around a central axis and a movement mechanism. The movement mechanism has three linkage assemblies connected to an end effector in parallel. The three assemblies are respectively driven by the three drivers in a linear or rotary manner for enabling the end effector to linearly move in a three-dimensional space. Each linkage assembly has three linkage rods and three rotating joints. An inner angle defined between each rotating joint and an imaginary plane being perpendicular to the central axis is an acute angle. A first center distance between the first rotating joint and the second rotating joint is equal to a second center distance between the second rotating joint and the third rotating joint. The overall height of the movement mechanism is reduced for increasing the working stroke and for improving the movement stability of the 3-axis parallel linear robot.

Abstract: An additive manufacturing (AM) method is provided. The method includes performing a laser powder bed fusion (L-PBF) process on the powder layer. Then, a first surface roughness value of the powder layer after the L-PBF process is obtained to generate a first surface profile. An absorptivity and a set of re-melting process parameters data are used to perform a heat transfer simulation. A second surface profile of the powder layer after laser re-melting is obtained by using the first surface profile and a low-pass filter. Then, the set of re-melting process parameters data is adjusted iteratively to perform the heat transfer simulation until a second surface roughness value predicted from the second surface profile is smaller than or equal to a surface roughness threshold, thereby obtaining optimal values of re-melting process parameters for performing a re-melting process to reduce a surface roughness of a powder layer after the L-PBF process.
