Fused deposition modeling (FDM®) and PolyJet® are two of the most advanced and effective additive manufacturing (AM) or 3D printing technologies available. They span the range from budget-friendly, desktop modeling devices to large-format, factory-floor equipment that draw from the capital expenditure budget, and can produce a range of output from precise, finely detailed models to durable production goods. While there is crossover in applications and advantages, these two technology platforms remain distinct and bring different benefits. Understanding the differences is the baseline for selecting the right technology for your application, demands and constraints.
