1. Experimental Sample,Equipment,sukaranan

sample:Bloomden Products 3D-pro-ml-A1,3D-pro-ml-A2,3D-pro-ml-A3

Equipment:Bloomden Sintering Furnace Model#:B1700


Experiment comparison of sintering sistema:

a. Bloomnden 3D series products recommended sintering temperature curve

Conclusion:As experiment result, 1480℃ is more recommend sintering temperature than 1530.At the sintering temperature of 1530℃ ,all color of 3D-pro-ml-A1,3D-pro-ml-A2 and 3D-pro-ml-A3 are lighter than 1480.After sintered at 1530,the color of 3D-pro-ml-A3 tooth is more like A2, and 3D-pro-ml-A1 and 3D-pro-ml-A2 is lighter than A1 on color sheet.

3. Analysis and Suggestion

analysis:As result of the material of 3D series products is a multi-powder mixture and it`s contain many high permeability UT powder.Considering the suggested sintering temperature range of UT powder is 1430℃——1480,which is much lower than 1530.Therefore,when sintered products at 1530℃ will cause abnormal growth of zirconia crystals in the product and affect the color of the product.


Sugesstion :We recommend 3D products are sintered at temperature of 1480,and the temperature range should not exceed 1450℃ - 1500.
