Abstract: A system including a printability analyzer, executed by at least one hardware processor, that ascertains, from an electronic three-dimensional printing file for a three dimensional part to be printed, three-dimensional printing constraints that include a design constraint, a material constraint, and a dimension constraint, ascertains a plurality of attributes for each three-dimensional printer of a plurality of three-dimensional printers, compares the three-dimensional printing constraints from the electronic three-dimensional printing file for the three-dimensional part to be printed to each attribute of the plurality of attributes for each three-dimensional printer of the plurality of three-dimensional printers, and determines, based on the comparison, whether the three-dimensional part is printable by at least one three-dimensional printer of the plurality of three-dimensional printers or not printable by any three-dimensional printer of the plurality of three-dimensional printers, a print evaluator, executed by the at least one hardware processor, that either a) ascertains, based on a determination that the three-dimensional part is printable by the at least one three-dimensional printer of the plurality of three-dimensional printers, costs associated with three-dimensional printing of the three-dimensional part and non-three-dimensional printing based manufacturing of the three-dimensional part, and determines, based on an analysis of the costs associated with the three-dimensional printing of the three dimensional part and the non-three-dimensional printing based manufacturing of the three dimensional part, whether the three-dimensional part is to be printed by the at least one three-dimensional printer of the plurality of three-dimensional printers, or b) determines, based on a determination that the three-dimensional part is not printable by any three dimensional printer of the plurality of three-dimensional printers, whether the design constraint or the material constraint of the three-dimensional part to be printed is not respectively met by a design attribute or a material attribute of any three-dimensional printer of the plurality of three-dimensional printers, and i. based on a determination that the design constraint of the three-dimensional part to be printed is not met by the design attribute of any three-dimensional printer of the plurality of three-dimensional printers, specifies a redesign for the three-dimensional part to be printed to meet the design attribute of at least one three-dimensional printer of the plurality of three-dimensional printers, or ii. based on a determination that the material constraint of the three dimensional part to be printed is not met by the material attribute of any three-dimensional printers, specifies an alternate material for the three-dimensional part to be printed to meet the material attribute of at least one three-dimensional printer of the plurality of three dimensional printers, and determines, based on the redesign for the three-dimensional part to be printed meeting the design attribute of at least one three dimensional printer of the plurality of three-dimensional printers or based on the alternate material for the three dimensional part to be printed meeting the material attribute of at least one three dimensional printer of the plurality of three-dimensional printers, whether the three dimensional part is to be printed by the at least one three-dimensional printer of the plurality of three-dimensional printers, and a digital integrator, executed by the at least one hardware processor, that ascertains, based on a determination that the three-dimensional part is to be printed by the at least one three-dimensional printer of the plurality of three dimensional printers, the electronic three-dimensional printing file for the three-dimensional part to be printed, controls, by a distributed electronic ledger including a blockchain network, execution of the electronic three-dimensional printing file for the three-dimensional part to be printed, and controls, by the distributed electronic ledger and based on the execution of the electronic three-dimensional printing file for the three-dimensional part to be printed, printing of the three-dimensional part. zO z ( O0c 0c LU 0z w 0z~ U)~c J) (NJ 7 Z Z <J Z Z < < << LL 0 U < (W D DO NC)H (Z HH - 0= Zn < 0 0WV FI0 N____<_0_w -j -j z QCJ) -: H U)m0 zz 0L LL= E3Z C)O 0C) I LWLJo~H o Z wu 00 0 z 0 . z _W0U <5 i : 0 jF --I
