Abstract
Example systems relate to reflective barriers. In some examples, devices utilizing reflective barriers can include a carriage device, comprising an enclosure to encase a plurality of energy sources directed in a particular direction, and a reflective barrier positioned within the enclosure, wherein the reflective barrier comprises a reflective insulation material.
Claims15
A carriage device, comprising:
- an enclosure to encase a plurality of energy sources directed in a particular direction;
- and
- a reflective barrier positioned within the enclosure, wherein the reflective barrier comprises a reflective insulation material.
A system, comprising:
- a build area comprising build material, wherein a first portion of the build area has a three dimensional (3D) printing agent deposited on the build material and a second portion of the build area that is free of the 3D printing agent;
- a carriage comprising a plurality of energy sources directed toward the build area;
- a reflective barrier positioned between the plurality of energy sources to receive reflected energy from the second portion of the build area and direct reflected energy to the first portion of the build area.
A three dimensional (3D) printing device, comprising:
- a build area comprising build material, wherein a first portion of the build area has a fusing agent deposited on the build material and a second portion of the build area has less fusing agent compared to the first portion;
- a carriage comprising a plurality of heat lamps directed toward the build area;
- a plurality of reflective barriers that correspond to each of the plurality of heat lamps to receive reflected energy from the second portion of the build area and direct reflected energy to the first portion of the build area, wherein the plurality of reflective barriers surround an area within the carriage to separate each of the plurality of heat lamps.
