Parameter value, the relative size requirements of the forming platform size and the motion axis stroke are added (see Chapter 4, GB/T 20318-2006
Table 1);
---Added general requirements such as "machine tool leveling", "diagrams", "software compensation" and "machining accuracy inspection" (see 5:3, 5:7, 5:8, 5:11);
---Changed the X and Y coordinate directions of the X-axis motion straightness check (see G1 item of 6:1, 5:1 of GB/T 20317-2006
G1 item);
---Changed the inspection steps in geometric accuracy inspection and positioning accuracy inspection (see Chapter 6 and Chapter 7, GB/T 20317-2006
of Chapters 5 and 6);
---Changed the structure of the chapter "Machining Accuracy Inspection" and deleted Appendix A; added test piece processing conditions and detection methods, changed
Results statistical analysis methods and confidence indicators (see Chapter 8, Chapter 7 and Appendix A of GB/T 20317-2006):

Introduction
GB/T 20317-2006 "Accuracy Inspection of Fused Deposition Rapid Prototyping Machine Tools" and GB/T 20318-2006 "Fused Deposition Rapid Prototyping Machine Tools"
"Shape Machine Tool Parameters" is my country's earliest national standard for machine tool accuracy inspection in the additive manufacturing industry: After more than ten years of technological development, Melt
The precision inspection and parameters of fused deposition rapid prototyping machine tools have gradually become clearer with the promotion of product applications and the improvement of technology maturity:
and specifications: This document combines the current design, production, use and other needs of melt extrusion deposition forming machine tools, in terms of machine tool structure, parameters, accuracy, etc:
In terms of aspects, the:2006 version of the standards has been integrated and revised:
Melt extrusion deposition forming machine tool accuracy inspection
1 Scope
This document specifies the structure and parameters, general principles, geometric accuracy inspection, positioning accuracy inspection and machining precision of melt extrusion deposition forming machine tools:
degree inspection: This document also gives tolerance values corresponding to the above inspections:
This document is suitable for inspection of the accuracy of melt extrusion deposition forming machine tools:

3 Terms and definitions
The terms and definitions defined in GB/T 14896:7 apply to this document:
4 Structure and parameters
4:1 The structure of the melt extrusion deposition forming machine tool (hereinafter referred to as the "machine tool") is shown in Figure 1:
4:2 When designing the travel in the X-axis, Y-axis and Z-axis directions, it is preferred to use the R'10 number system in GB/T 19764-2005 (the common ratio is
1:25):
4:3 The length (or diameter) of each side of the forming platform should not be less than 20mm of the corresponding X-axis and Y-axis travel:
4:4 When designing the nozzle diameter, the R'20 number system in GB/T 19764-2005 (common ratio is 1:12) is preferred:
