Problems solved by technology
[0016] At present, due to the fact that 3D printing technology has not yet formed a scale effect in practical applications, there are few evaluation methods for the quality of 3D printer prints, most of which are based on visual inspection, comparison, and descriptive content. The evaluation process is highly subjective, and the content Insufficient, the results are not objective and accurate enough, and lack the support of rational analysis and measurement data, which are mostly seen in the evaluation articles of IT websites and 3D printing websites
[0017] The performance indicators of 3D printer prints include: printing accuracy, minimum printing gap, resolution, bridging performance, drape performance, bonding strength, surface waviness, minimum printing layer thickness, verticality, etc., one or more of which are not It is impossible to better evaluate the quality of printed products, and there is no comprehensive and comprehensive evaluation method at present

Embodiment Construction
[0070] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0071] like Figure 1-23 Shown, a kind of fused deposition (FDM) formula 3D printer printing product evaluation method comprises the following steps:
[0072] Step 1: Use the fused deposition (FDM) 3D printer to be tested to print the specified test model under the factory default standard setting conditions to obtain the corresponding printed products;
[0073] Step 2: Use detection tools, calculation formulas or visual inspection to measure the value and appearance of the printed product respectively: analyze and obtain the printing accuracy, resolution, bridging performance, drape performance, bonding strength, Surface waviness, minimum print layer thickness and perpendicularity;
[0074] Step 3: Print the specified test model under the condition of the optimal setting of the fused deposition (FDM) 3D printer to be tested, and the printed test...

The invention relates to a fused deposition modeling (FDM) type 3D printer printed product evaluation method. The method includes the following steps that: an FDM type 3D printer to be tested prints aprescribed test model under a factory default standard setting condition or optimal setting condition, so that a corresponding print product can be obtained; and the numerical value and appearance ofthe print product are measured by using a detection tool, a calculation formula, or visual inspection: the printing accuracy, minimum print gap, resolution, bridging performance, suspension performance, bonding strength, surface waviness, minimum print layer thickness and verticality of the FDM type 3D printer to be tested are obtained through analysis. According to the method of the invention, the reasonable evaluation items, detection method, detection tool, calculation formula and the like for the printed product are stipulated according to the formation process of the 3D printer and the characteristics of consumables, and the quality of the printed product can be objectively and accurately analyzed.
Description
technical field [0001] The invention relates to the technical field of 3D printers, in particular to a method for evaluating printed products of a fused deposition (FDM) 3D printer. Background technique [0002] Explanation of terms about 3D printing: [0003] Fused deposition (FDM) fused deposition modeling, extruding a filament of filamentary material from a heated nozzle, deposits at a fixed rate according to the predetermined trajectory of each layer of the part. [0004] Standard setting standard setting, the standard configuration of various parameters when the product's slicing software slices the model file (the software should give this configuration and it is the default). [0005] The best setting is best setting, the best configuration of various parameters when the product's slicing software slices the model file (the software should provide this configuration). [0006] Printing accuracy print precision, the error between the actual size of the printed produc...
