Hızlı Prototip Oluşturmada Karşılaşılan Problemler Ve Çözüm Önerileri

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 İmalatı, 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

Problems Encountered During The Rapid Prototyping And Their Solution Proposals

Rapid Prototyping (RP) is intended to produce physical objects as thin layers from Computer Aided Design (CAD) data. Real models produced this way can be used in a variety of business and operations (various tests, dimensional control, casting models, customer offers / presentations, prototypes and even real parts and so on.). Many technologies and methods have been developed in this area in recent years. These include: Stereolithography (can be termed as optical production, photo-solidification and so on), Selective Laser Sintering, Fused Deposition Modelling, 3D printing, Laminated Object Manufacturing, Multi-jet Modelling, Laser Net Shaping and so on. With this technology and methods, easy, fast, inexpensive and automatic models can be developed. However, some specific and general problems may be encountered during the application. Such problems are; complex and large parts modelling, disassembly, dimensional accuracy, surface accuracy, processing speed, and so on. In this paper, general and specific problems encountered during the rapid prototyping will be discussed and solutions will be introduced
