The 3D printer that helps us recreate vintage film equipment
Obsolete technologies pose a challenge for archivists working to preserve vintage film and TV, but this state-of-the-art 3D printer has been a game changer in allowing us to recreate accurate new parts.
Tucked away in the BFI National Archive is a machine that looks like it belongs in a sci-fi lab – but it’s quietly revolutionising how our film heritage is preserved. Meet the Formlabs Form 3L, a large-format 3D printer that’s helping our archive technology team tackle the tricky problem of obsolete equipment and prototype new solutions.
Purchased in 2022, the Form 3L is a versatile printer that allows us to produce a wide range of parts essential for maintaining equipment. Its large build volume and precision enable the creation of accurate parts, from film reels and cores to spacers and guides. This printer breathes new life into ageing film technology.
The workflow begins with the EinScan Pro HD 3D scanner, which captures detailed 3D models of existing parts. The team refines the model using SolidWorks, a powerful computer-aided design software, before printing with the Form 3L. The printer uses photopolymer resin and Formlabs’ advanced Low Force Stereolithography (LFS) technology for superior surface finish and accuracy.
After printing, parts undergo post-processing with the Form Cure L, ensuring optimal mechanical properties and stability. This step is critical for components that may be subjected to mechanical stress or environmental factors when used in vintage equipment.
The Form 3L’s capabilities extend beyond replicating obsolete parts. The team also uses it for prototyping new components, such as guide rollers for a 2-inch video tape cleaner. These prototypes were perfected in resin before being sent for metal manufacturing, showcasing the printer’s role in the product development cycle.
The adoption of the Formlabs Form 3L represents a perfect fusion of preservation and innovation. By harnessing 3D printing, we ensure that priceless film artefacts remain accessible for future generations while pushing the boundaries of archival technology forward.
