Current Status and Prospects of Polymer Powder 3D Printing Technologies
Open accessAbstract
3D printing technology, which greatly simplifies the manufacturing of complex parts by a two-dimensional layer-upon-layer process, has flourished in recent years. As one of the most advanced technology, polymer powder 3D printing has many advantages such as high materials utilization rate, free of support structure, great design freedom, and large available materials, which has shown great potential and prospects in various industry applications. With the launch of the Multi jet Fusion system from HP, polymer powder 3D printing has been attracting more attention from industries and researchers. In this work, a comprehensive review of the main polymer powder-based 3D printing methods including binder jetting, selective laser sintering, high-speed sintering were carried out. Their forming mechanism, advantages and drawbacks, materials, and developments were presented, compared, and discussed respectively. In addition, this paper also gives suggestions on the process selection by comparing typical equipment parameters and features of each technology.

SLS is suitable for the fabrication of scaffolds with complex geometric shapes and is especially suitable for bone tissue scaffolds because of its high mechanical strength and porosity.
“This method is suitable for the fabrication of scaffolds with complex geometric shapes, and is especially suitable for the construction of bone tissue scaffolds because of its high mechanical strength and porosity [105, 106].”
From Application of PLCL as a biodegradable polymer in biomedical engineering (2026) · cites this paper as [106]
Section 3.3.3 (page unavailable) says SLS has prospects in tissue engineering and describes a scaffold made by SLS with stable mechanical properties. Section 3.1 describes accurate, customizable parts. The paper does not establish that SLS is especially suitable for bone scaffolds because they combine high strength and porosity; Section 3.3.1 instead describes porous parts made at low energy density as weak.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
