Accuracy and precession of 3d printed cast produced by two printing techniques

[摘要] 0.05, proving normality. ANOVA was used to compare printers' accuracy. Results. Table 1 shows the means and SDs. Wilk's Lambda of p.05 (F = 95.533 and partial eta squared = 0.841) reveals an initial and six-month accuracy difference. A P 0.05 within-subject’s tolerance effect was found. P=.503 demonstrates printer type doesn't affect participation. The study's mean was.995, with a standard error of.066 and CI of.856 to 1.134. Conclusion. The accuracy measurement decreased significantly between the initial and six-month measurements. There was no difference in accuracy between the two measurements for either printer. There was a statistically significant difference between each cast and each printer's first STL file information. However, the distinction was within the accepted tolerance of -/+ 42 µm (Envision TEC reported an accepted tolerance level).
