The digitisation of cultural heritage, particularly within national collections such as those of Heritage Malta, presents a blend of opportunities and challenges. The establishment of the Digitisation Unit has been pivotal in adopting 3D digitisation technology, which enhances the preservation and accessibility of the National Collection. However, the lack of common international standardised methodologies and procedures has led to inconsistencies in the quality and interoperability of 3D models. This paper explores the critical differences between 2D and 3D digitisation, highlighting the advanced equipment and methodological complexities involved in 3D processes. It discusses the experiences faced during the digitisation of the National Collection, with a focus on item prioritisation and the need for robust strategies and standards. The importance of metadata and paradata, along with equipment and methodological challenges, are examined to illustrate the multifaceted nature of 3D digitisation. Despite these challenges, strategic actions such as developing internal guidelines, investing in storage solutions, and participating in initiatives like TwinIt! are identified as crucial for overcoming current barriers. The paper concludes that while the field of 3D digitisation is still evolving, the concerted efforts of institutions like Heritage Malta, coupled with ongoing innovations and standardisation efforts, hold promise for preserving and sharing cultural heritage with future generations, ensuring its accessibility and integrity in the digital age.
