A forming control apparatus comprising: a forming control means arranged to control a forming process performed by a forming unit for forming a three-dimensional object in a first three-dimensional space where one or more objects is formable; a forming management means arranged to manage information on a first object to be formed by the forming unit and specify a second three-dimensional space required to form the first object in the first three-dimensional space; a reception means arranged to receive, during the forming process for the first object performed by the forming unit, an instruction to form a second object, which is different from the first object, and forming data corresponding to the second object; and a notification means arranged to issue a completion notification, wherein the forming management means is further arranged to: specify a third three-dimensional space where an object is additionally formable by the forming unit, based on the first three-dimensional space and the second three-dimensional space; predict (i) a forming time period to be taken until the forming process for the first object is completed and (ii) after the forming time period is predicted and in a response to the reception of the instruction to form the second object during the forming process for the first object, a total time period to be taken until both a forming process for the first object currently being formed and a forming process for the second object subsequently to be formed are completed; and determine whether or not the second object is formable in the third three-dimensional space, wherein the forming control means is further arranged to, in a case where the forming management means determines that the second object is formable in the third three-dimensional space, issue a forming control command based on the forming data corresponding to the second object in the third three-dimensional space, in addition to a forming control command for forming the first object, wherein the notification means issues the completion notification in a case where both the forming process for the first object and the forming process for the second object are completed. a forming control means arranged to control a forming process performed by a forming unit for forming a three-dimensional object in a first three-dimensional space where one or more objects is formable;
