Purpose

A three-dimensional (3D) printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy. The purpose of this study is to analyze the influence of such errors on printing accuracy and printing quality for delta-robot 3D printer.

Design/methodology/approach

First, the kinematic model of a delta-robot 3D printer with an ideal geometric structure is proposed by using vector analysis. Then, the normal kinematic model of a nonideal delta-robot 3D robot with tilted vertical beams is derived based on the above ideal kinematic model. Finally, a 3D printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy.

Findings

The results show that tilted vertical beams can indeed cause 3D printing errors and further influence the 3D printing quality of the final products and that the 3D printing errors of tilted vertical beams are related to the rotation angles of the tilted vertical beams. The larger the rotation angles of the tilted vertical beams are, the greater the geometric deformations of the printed structures.

Originality/value

Three vertical beams and six horizontal beams constitute the supporting parts of the frame of a delta-robot 3D printer. In this paper, the orientations of tilted vertical beams are shown to have a significant influence on 3D printing accuracy. However, the effect of tilted vertical beams on 3D printing accuracy is difficult to capture by instruments. To reveal the 3D printing error mechanisms under the condition of tilted vertical beams, the error generation mechanism and the quantitative influence of tilted vertical beams on 3D printing accuracy are studied by simulating the parallel motion mechanism of a delta-robot 3D printer with tilted vertical beams.

delta-robot 3D打印机倾斜垂直梁打印误差研究

目的

提出了一种三维（3D）打印误差模拟方法来分析倾斜的垂直梁对3D打印精度的影响。本研究的目的是分析此类误差对delta-robot 3D打印机打印精度和打印质量的影响。

设计/方法/方法

首先，通过矢量分析，提出了具有理想几何结构的delta-robot 3D打印机的运动学模型。然后，基于上述理想运动学模型推导出具有倾斜垂直梁的非理想三角形机器人3D机器人的法向运动学模型。最后，提出了一种3D打印误差模拟方法来分析倾斜垂直梁对3D打印精度的影响。

发现

结果表明，倾斜的垂直梁确实会导致3D打印误差，并进一步影响最终产品的3D打印质量，倾斜的垂直梁的3D打印误差与倾斜的垂直梁的旋转角度有关。倾斜的垂直梁的旋转角度越大，印刷结构的几何变形越大。

原创性/价值

三根竖梁和六根横梁构成了delta-robot 3D打印机框架的支撑部分。在本文中，倾斜的垂直梁的方向被证明对 3D 打印精度有显着影响。然而，倾斜的垂直光束对 3D 打印精度的影响很难被仪器捕捉到。为揭示垂直梁倾斜条件下的3D打印误差机制，通过模拟具有倾斜垂直梁的delta-robot 3D打印机的平行运动机制，研究了倾斜垂直梁的误差产生机制和对3D打印精度的定量影响.
