Hızlı Prototip Oluşturma (HPO, Rapid Prototyping - RP), Bilgisayar Destekli Tasarım (CAD) verisinden ince tabakalar şeklinde fiziki nesneler üretmeyi amaçlar. Böylece oluşan gerçek modeller çeşitli iş ve işlemlerde kullanılabilir (çeşitli testler, boyut kontrolü, döküm model, müşteriye teklif/sunu, prototip ve hatta gerçek parça vb.). Son yıllarda bu alanda birçok teknoloji ve yöntem geliştirilmiştir. Bunlar arasında: Stereolitografi (optik üretim, foto katılaştırma vb. de denebilir), Seçici lazer sinterleme, Ergiyik birikimli modelleme, 3B baskı (3 Boyutlu baskı), Katmanlı nesne imalatı, Çok püskürtmeli modelleme, Lazerle yapılan net biçimlendirme vb. gösterilebilir. Bu teknoloji ve yöntemler ile kolay, hızlı, ucuz ve otomatik modeller geliştirilebilir. Ancak, uygulama esnasında ise bazı özel ve genel problemlerle karşılaşılabilir. Bu tür problemler arasında; karmaşık ve büyük parçaları modelleme, demontaj, ölçü tamlığı, yüzey hassasiyeti, işlem hızı vb. gibileri gösterilebilir. Bu makalede hızlı prototip oluşturma esnasında karşılaşılan özel ve genel problemler ele alınacak ve çözüm yolları tanıtılacaktır.
