Recent progress of 3D printed continuous fiber reinforced polymer composites based on fused deposition modeling: a review

3D Printing, utilizing a layer-by-layer deposition of materials, is advantageous to manufacture parts as it involves fewer process steps, provides great flexibility for prototyping, especially of complex parts, and has low material waste. Yet, the mechanical properties of 3D printed parts have always been a concern due to the weak inter-layer bonding and rough surface. 3D printed continuous fiber reinforced polymer composites (CFRPCs) use...
