Part strength improvement in polymer shape deposition manufacturing

John Kietzman, Byong‐Ho Park, Friedrich Prinz

Shape deposition manufacturing (SDM) is a layered manufacturing process which iteratively combines material addition and removal to create artifacts in a variety of materials…

Computer aided decision support for fused deposition modeling

C.W. Ziemian, P.M. Crawn

Parts formed using fused deposition modeling (FDM) can vary significantly in quality depending on the manufacturing process plan. Altering the plan profoundly affects the…

Mechanical behavior of acrylonitrile butadiene styrene (ABS) fused deposition materials. Experimental investigation

José F. Rodríguez, James P. Thomas, John E. Renaud

An experimental study of the mechanical behavior of fused‐deposition (FD) ABS plastic materials is described. Elastic moduli and strength values are determined for the ABS…

Experimental investigation of nanosecond pulsed Nd:YAG laser re‐melted pre‐placed powder beds

R. Morgan, C.J. Sutcliffe, W. O’Neill

Describes the effects of the major process variables (Q‐switch pulse frequency, laser power, scan speed, scan spacing and scan length) on the production of single layer coupons…

Production tooling for polymer moulding using the RapidSteel process

Kenny Dalgarno, Todd Stewart

Presents procedures which were developed for the manufacture of production tooling using the DTM RapidSteel process, and on the methodology adopted in the generation of the…

Density prediction of crystalline polymer sintered parts at various powder bed temperatures

Alva E. Tontowi, T.H.C. Childs

The effect of powder bed temperature setting on the prediction of density of sintered parts produced by the selective laser sintering (SLS) process is reported. A crystalline…
