  Title Mechanical characterisation of anisotropic silica sand/furan resin compound induced by binder jet 3D additive manufacturing technology Type Journal Article
  Year 2020 Publication Ceramics international Abbreviated Journal  
  Volume 46 Issue 11 Pages 17867-17880  
  Keywords 3D sand print process ; Compression test ; Mechanical characterisation ; Microstructural ; Printing parameter  
  Abstract Binder jet 3D printing of ceramic materials is an additive manufacturing technology that enables the production of complex and multi-functional parts through the selective jet binding of precursor powder beds. The present study makes use of the 3D Sand Printing (3DSP) process to create moulds and cores in the casting industry. The use of the 3DSP components as functional parts in industrial production is limited due to the uncertainty associated with their mechanical properties, such as their permeability and thermal stability. Moreover, because of the porous nature of their printed structures, their mechanical properties are dispersed and rather difficult to reproduce. This study aims to characterise the impact of different printing parameters on the mechanical performance of printed parts. For this purpose, a specific device was made in order to assess the mechanical characteristics of samples printed via this technique. The effects of processing parameters such as the printing orientation and building direction on the compressive properties of the printed specimens have also been carefully studied. Microstructural analyses were performed to better understand the relationship between the 3DSP process and the mechanical properties of the components produced from it. The results show that the mechanical tests carried out significantly improve the property reproducibility of the samples made using this technique.

  Title Effect of Curing Methods on Shrinkage Development in 3D-Printed Concrete Type Journal Article
  Year 2020 Publication Materials Abbreviated Journal  
  Volume 13 Issue 11 Pages 2590  
  Keywords 3D Concrete Printing ; additive manufacturing ; curing conditions ; digital construction ; shrinkage  
  Abstract Technological developments in construction have led to an increase in the use of 3D modelling using CAD environments. The popularity of this approach has increased in tandem with developments in industry branches which use 3D printers to print concrete based printing materials in construction, as these allow freedom in shaping the dimensions of supporting elements. One of the biggest challenges for researchers working on this highly innovative technology is that of cement material shrinkage. This article presents the findings of research on an original method of measuring deformations caused by shrinkage in 3D-printed concrete elements. It also discusses the results of tests on base mixes, as well as comparisons between the influence of internal and external curing methods on the development of deformations and their final outcomes. Furthermore, the article discusses differences between deformations formed after seven days of hardening without curing, with those which occur when two common, traditional concrete curing methods are used: foil insulation and shrinkage reducing admixtures. In addition, the article examines the effects of internal curing on the 1, 7, 14, 21 and 28 day mechanical properties of concrete, in accordance with EN 196-1 and EN 12390-2. Studies have shown that the optimal amount of shrinkage reducing admixtures is 4% (in relation to the mass of cement), resulting in a reduction in total shrinkage of 23%. The use of a shrinkage reducing admixture in 3D-printed concrete does not affect their strength after 28 days, but slows the strength development during the first 7 days.

  Title Large-scale 3D printers for additive manufacturing: design considerations and challenges Type Journal Article
  Year 2019 Publication International journal of advanced manufacturing technology Abbreviated Journal  
  Volume 104 Issue 9-12 Pages 3679-3693  
  Keywords CAE) and Design ; Computer-Aided Engineering (CAD ; Engineering ; Industrial and Production Engineering ; Mechanical Engineering ; Media Management ; Original Article  
  Abstract Since the advent of 3D printing in the mid-1980s, additive manufacturing has grown steadily and found numerous applications across all types of industries. More recently, the industry has seen a spur of growth as the terms of the original patents expired and new companies entered the market. While there exist several different methods of additive manufacturing, polymer-based material extrusion 3D printing (also known as fused filament fabrication) has become one of the most widely used ones due to its lower cost, ease of use, and versatility. While development has greatly expanded the material availability and improved the quality of prints, material extrusion 3D printers have often faced a challenge in physical scaling. There are inherent design hurdles to the extrusion process when the print starts to grow larger. This paper aims to study the market landscape of extrusion-based 3D printing technology for polymer-based material as well as challenges faced in upscaling this technology for industrial applications. A prototype large-scale material extrusion 3D printer has been designed, constructed, and then tested to gain experimental data on large-scale 3D printing using thermoplastic polymers as a printing material. Results of testing and experimentation verified certain key design elements and how they can improve large-scale 3D printing. Testing also revealed how large diameter nozzles for the hot end introduce challenges not seen in small-scale 3D printers. This paper also seeks to consolidate available information pertaining to large-scale 3D printing into one comprehensive document.

  Title Development of Communication Protocols between BIM Elements and 3D Concrete Printing Type Journal Article
  Year 2021 Publication Applied sciences Abbreviated Journal  
  Volume 11 Issue 16 Pages 7226  
  Keywords 3D concrete printing ; additive manufacturing ; building information modeling ; communication protocols  
  Abstract Historically, the construction industry has exhibited slow technological development when compared to other industries. However, during the last several years, investigations related to automation in construction have been conducted, such as additive manufacturing in concrete. This study aims to delve into this topic, providing effective communication between BIM-designed elements and its additive concrete manufacturing, with the help of an articulated robotic arm. Therefore, the paper addresses the preparation of computer code that allows such BIM-robot communication, checking the parameters utilized, and analyzing the results of tests with the equipment involved.
