PREFABRİK BETON ELEMAN ÜRETİMİNDE ABS MALZEMEDEN EKLEMELİ İMALATLA ÜRETİLMİŞ KALIPLARIN GELENEKSEL YÖNTEMLERLE KONTRPLAK MALZEME İLE ÜRETİLMİŞ KALIPLARLA KARŞILAŞTIRILMASI: YÜZEY KALİTESİ VE TEKRAR KULLANIM PERFORMANSINA YÖNELİK DENEYSEL BİR DEĞERLENDİRME

Abstract

Bu çalışma, prefabrik beton elemanların üretim sürecinde kullanılan kalıpların malzeme türü ve üretim yöntemi bağlamında yüzey kalitesine etkisini incelemektedir. Araştırma kapsamında, ABS termoplastikten eklemeli imalat yöntemiyle üretilmiş kalıplar ile geleneksel kontrplak malzeme kullanılarak elde edilen kalıplar karşılaştırmalı olarak değerlendirilmiştir. Her iki kalıpla üretilen beton numuneler; yüzey pürüzlülüğü, detay aktarım hassasiyeti, üretim süreci verimliliği ve kalıp tekrar kullanımı bakımından analiz edilmiştir. Deneysel bulgular, eklemeli imalatla elde edilen ABS kalıpların daha düşük yüzey pürüzlülüğü ve yüksek geometrik hassasiyet sunduğunu; buna karşılık geleneksel kontrplak kalıpların üretim süresi ve dayanıklılık bakımından daha avantajlı olduğunu ortaya koymaktadır. Söz konusu sonuçlar doğrultusunda, ABS bazlı kalıpların prototip üretimi ve özel tasarım odaklı uygulamalar için uygunluk taşıdığı; ancak uzun vadeli kullanım ve seri üretim süreçlerinde iyileştirilmesi gereken yönleri bulunduğu değerlendirilmektedir. Araştırma bulguları, yapı endüstrisinde alternatif kalıp teknolojilerine yönelik farkındalık oluşturmaya katkı sağlamaktadır. Ayrıca sürdürülebilir üretim ve geri dönüştürülebilir malzeme kullanımı çerçevesinde yapılacak ileri düzey çalışmalar için literatüre yönlendirici öneriler sunmaktadır.

COMPARISON OF MOLDS PRODUCED USING ADDITIVE MANUFACTURING WITH ABS MATERIAL IN PRECAST CONCRETE ELEMENT PRODUCTION WITH MOLDS PRODUCED USING TRADITIONAL METHODS WITH PLYWOOD MATERIAL: AN EXPERIMENTAL EVALUATION FOCUSING ON SURFACE QUALITY AND REUSABILITY PERFORMANCE

Abstract

This study investigates the impact of formwork material type and production method on the surface quality of precast concrete components. Within the scope of the research, formworks fabricated from ABS thermoplastic using additive manufacturing technologies are comparatively evaluated against conventionally produced plywood formworks. Concrete samples cast with each formwork type were analyzed in terms of surface roughness, detail transfer accuracy, process efficiency, and reusability. Experimental findings reveal that ABS-based formworks produced through Fused Deposition Modeling offer superior geometric fidelity and lower surface roughness compared to their plywood counterparts. However, conventional plywood formworks displayed greater advantages in terms of production time and material endurance during prolonged use. These results suggest that ABS formworks are particularly well-suited for prototyping and design-oriented applications requiring high surface precision. Conversely, further development is needed for their integration into long-term industrial production processes due to mechanical durability and cost implications. The insights gained through this study contribute to the growing awareness surrounding alternative formwork technologies in the construction industry. Furthermore, the findings offer valuable recommendations for future research initiatives aimed at improving sustainable production practices and enhancing the use of recyclable materials in concrete formwork systems.
