然而，已知该方法比立体光刻方法具有优势，这意味着需要在树脂上仅有浅槽以促进工艺，这主要导致产生更少的浪费和更低的成本运行。再往前看，光聚合物的树脂已知被置于具有可在其内部移动的平台的槽内（Bump 2013），这是事实。此外，已经进一步确定了最基本和容易识别的过程被称为沉积。而且，这个特定的过程已经被许多3D入门级打印机所采用。

激光的熔化或烧结

已知激光的熔化和烧结是可互换的术语，被称为基于激光的3D打印过程，似乎与粉末材料一起工作。激光跟踪是通过一层粉末状的粉末材料完成的，根据三维数据在X轴和Y轴（Fitzgerald 2013）内的轴向数据进行紧密压缩。由于激光与粉末材料表面相互作用，最终烧结或熔化，彼此的粒子形成固体。随着每一层的完成，粉末床层以递增的方式最终落下，并且在下一个激光束通过以形成随后的层之前，辊子有助于使粉末在床上平滑化，并且这种融合与前一层一致（Cronin 2012）。

However, this process is known to be having an advantage over the processes of stereo lithography that means that there is a need for having only a shallow vat over resin for the facilitation of process that mostly leads towards the generation of less waste and lower costs of running. Further ahead, there is no denial in the fact that the resin of photopolymer is known to be held within a vat having a platform that can move inside (Bump 2013). Also, it has further been identified that the most basic and easily identified process is referred to as deposition. And, this particular process has been employed by a number of printers of 3D at the entry level.

Melting or Sintering of Laser

Melting and sintering of laser are known to be interchangeable terms that are referred to as a 3D printing process based on laser that seems to be working with materials of powder. The tracing of laser is done across a bed of powder over powdered material that is tightly compacted as per the data of 3D being fed to the machines within the axes of X and Y(Fitzgerald 2013). As there is interaction of laser with surface over the material of powder it ends up sintering or fusing, the particles of each other for the formation of solid. As there is completion of each and every layer, the bed of powder ends up dropping in an incremental manner and a roller helps in smoothening the powder on the bed before the next beam of laser passes for the formation of subsequent layers and the fusion of this is done in alignment with the previous layer (Cronin 2012).
