The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby a spreader device is used to deposit particulate material in layers on a build platform and the particulate material flow, which occurs perpendicular to the spreading direction, is transferred into containers that are actively cleaned by sliders or brushes at the spreader device. It exploits the fact that particulate material that is moves dynamically can only bridge small height differences. The arrangement can be implemented in a space-saving manner beneath the spreading plane.

1. A 3D printing process for manufacture of objects comprising steps of: depositing a layer of a particulate material on a build platform including spreading the particulate material with a spreader device, wherein overflow material flows into a first container and a second container on opposing sides of the build platform, each extending from a front of the build platform to a rear of the build platform, wherein each container ends at a same front and/or rear discharge recess;selectively printing a second material;repeating the depositing and printing steps until a desired object is achieved;wherein the build platform has a front end, a rear end, and opposing sides;wherein the process includes a step of transporting the overflow material along the first and second containers in a same direction to the front and/or rear discharge recess; and wherein the step of transporting the overflow material along the first and second containers is controlled by a movement of the spreader device. 2. The process of claim 1, wherein the step of spreading incudes moving the spreading device in a first direction from the back of the build platform to the front of the build platform; and the first and second containers includes a channel running parallel to the first direction and extends to the front of the discharge recess. 3. The process of claim 2, wherein the overflow material flows at least partially in a direction perpendicular to the first direction. 4. The process of claim 3, wherein the channel includes a front end having an opening for flow of the overflow material into a front discharge recess and a rear end having an opening for flow of the overflow material into a rear discharge recess, wherein the process includes transporting the overflow material along the channel and into the front discharge recess when the spreading device travels from the back of the build platform to the front of the build platform and/or transporting the overflow material along the channel and into the rear discharge recess when the spreading device travels from the front of the build platform to the back of the build platform. 5. The process of claim 1, wherein the first and second containers include a channel, wherein the channel includes a front end having an opening for flow of the overflow material into a front discharge recess and a rear end having an opening for flow of the overflow material into a rear discharge recess, wherein the process includes transporting the overflow material along the channel and into the front discharge recess when the spreading device travels from the back of the build platform to the front of the build platform and/or transporting the overflow material along the channel and into the rear discharge recess when the spreading device travels from the front of the build platform to the back of the build platform. 6. The process of claim 1, wherein the first container is parallel to the second container. 7. The process of claim 1, wherein each container is a channel having opposing side walls running a length of the build platform in a spreading direction. 8. The process of claim 1, wherein each container is entirely located beneath a spreading plane of the particulate material. 9. The process of claim 1, wherein each container is connected with the discharge recesses; the front discharge recess is located alongside a front edge of the build platform, and the rear discharge recess is located alongside a rear edge of the build platform, and the containers extend parallel to a first direction, so that particulate material can flow from the containers into the recesses; and wherein the first direction is a direction in which the spreading device moves during the spreading step. 10. The process of claim 1, wherein each of the containers have a horizontal floor running a length of the build platform in a spreading direction, wherein the floor is a solid floor, wherein the spreading direction is the first direction. 11. A 3D printing process for manufacture of objects comprising steps of: depositing a layer of a particulate material on a build platform including spreading the particulate material with a spreader device, wherein overflow material flows into one or more containers;selectively printing a second material;repeating the depositing and printing steps until a desired object is achieved;wherein the build platform has a front end, a rear end, and opposing sides;wherein the process includes a step of transporting the overflow material from the one or more containers to a front and/or rear discharge recess;wherein the step of spreading incudes moving the spreading device in a first direction from the back of the build platform to the front of the build platform; and the one or more containers includes a channel running parallel to the first direction and extends to the front of the discharge recess;wherein the overflow material flows at least partially in a direction perpendicular to the first direction;wherein the channel includes a front end having an opening for flow of the overflow material into a front discharge recess and a rear end having an opening for flow of the overflow material into a rear discharge recess, wherein the process includes transporting the overflow material along the channel and into the front discharge recess when the spreading device travels from the back of the build platform to the front of the build platform and/or transporting the overflow material along the channel and into the rear discharge recess when the spreading device travels from the front of the build platform to the back of the build platform;wherein a slider or a brush is mounted on the spreading device to act upon the one or more containers and move the overflow material therein towards a front and/or rear discharge recess. 12. The process of claim 11, wherein the one or more containers consists of a first container and a parallel second container, wherein the first and second containers are located along opposing sides of the build platform. 13. The process of claim 12, wherein each container is a channel having opposing side walls running a length of the build platform in the first direction. 14. The process of claim 13, wherein each container is entirely located beneath a spreading plane of the particulate material. 15. The process of claim 14, wherein each container is connected with the discharge recesses; the front discharge recess is located alongside a front edge of the build platform, and the rear discharge recess is located alongside a rear edge of the build platform, and the containers extend parallel to the first direction, so that particulate material can flow from the containers into the recesses. 16. The process of claim 15, wherein the containers are open containers, without a cover. 17. The method of claim 15, wherein each of the containers have a horizontal floor running a length of the build platform in a spreading direction, wherein the floor is a solid floor, wherein the spreading direction is the first direction. 18. The process of claim 11, wherein the brush is mounted on the spreader device and the process includes a step of the brush acting upon one of the containers to move the overflow material. 19. The process of claim 16, wherein the one or more containers are open containers, without a cover. 20. A 3D printing process for manufacture of objects comprising steps of: depositing a layer of a particulate material on a build platform including spreading the particulate material with a spreader device, wherein overflow material flows into one or more containers;selectively printing a second material;repeating the depositing and printing steps until a desired object is achieved;wherein the build platform has a front end, a rear end, and opposing sides;wherein the process includes a step of transporting the overflow material from the one or more containers to a front or rear discharge recess;wherein a slider or a brush is mounted on the spreading device to act upon the one or more containers and move the overflow material therein towards a front or rear discharge recess.
