By taking advantage of the warpage that is commonly considered as a defect of desktop fused deposition modeling (FDM) 3D printers, we demonstrated that with an FDM printer, off-the-shelf printing filaments and a design editor, we can print flat thermoplastic composites and trigger them to self-fold into 3D.
