Abstract

A computer-implemented method, a computer system and a computer program product split a virtual printing model according to a probability of multidimensional printing failure. The method includes obtaining a virtual printing model of a multidimensional object, where the virtual printing model comprises print layers. The method also includes determining that a printing risk score for a location on the multidimensional object is above a printing risk threshold. The method further includes mapping a set of print layers of the virtual printing model to the location on the multidimensional object. Lastly, the method includes sending the print layers of the virtual printing model to a multidimensional printer, wherein a mapped set of print layers is sent first.

Dependent claims

A computer-implemented method for splitting multidimensional print jobs according to a probability of multidimensional printing failure, the computer-implemented method comprising:

receiving a virtual printing model of a multidimensional object, wherein the virtual printing model comprises print layers for a multidimensional printer;
splitting the virtual printing model into sets of print layers, wherein each set of print layers corresponds to a location of the multidimensional object that are sized according to requirements of the multidimensional printer;
determining a printing risk score for each location on the multidimensional object;
determining at least one of the printing risk score being above a printing threshold,
identifying a set of print layers of the virtual printing model as a vulnerable location on the multidimensional object based on the at least one of the printing risk score being above a printing threshold;
sending the set of print layers associated with the vulnerable location of the virtual printing model to a first printer in decreasing order of printing risk score;
sending remaining print layers of the virtual printing model to a second printer;
and
detecting a print failure at the first printer;
in response to detecting the print failure at the first printer, blocking the second printer from printing the remaining print layers of the virtual printing model.
