- Number of hours to print (including failures and troubleshooting this crappy consumer 3D printer : ~48hours
- Cost of filament : Quite Affordable
- DIY Satisfaction and the film scanned : Priceless
This project was motivated by a friend of mine who has more than 10 rolls of films that she wanted to scan but with no accessible or affordable scanners. Instead of the closest thing you can get which is the Lomography Film Scanner (and many DIY methods out there), I decided to make my own version with 3D printer.
You can download the STL to modify or print on your own here. (zip is not supported by wordpress, so just rename the .doc to .zip).
Here is how it works:
The print consists of 3 modules (left to right):
- adapter_phone – Height adjusted for most smartphone, iphone, android to have enough focusing distance. A simple blue-tack to use as a universal phone sticker. The adapter was also designed keeping in mind if I can design a different module, example to mount to a DSLR.
- base – The main light preventing cover.
- film_holder – For elevating the film (will explain later).
Other components you would need:
- Scanner (a smartphone camera or any digital camera)
- Light box (a genuine light box or any smartphone that can load an app to display white screen)
Why do you need to elevate the film if you are using another phone as the light box? It is because if the film rest right on top on the LCD screen, you are likely to get this:
Thanks to the high definition nature of modern digital camera… you are likely to capture all the pixels from the LCD! iPhone’s poor interpolation algorithm will render it even worst. This is the reason where there is a 4mm elevation from the film_holder module to off-focus the LCD. 4mm is sufficient for DSLR, however if you still see the artifacts, just simply lift the whole thing further away from the ‘light box’.
This is the first prototype, more of a gift for my friend as I do not have that many film for scanning. Operation was okay, I like how the commercial product has a roller where you can shift the film, maybe this is some feature I shall design in the next prototype. Post-process picture by picture is a huge pain in the arse, I have yet to do any research on an automated batch process but I think there should be such softwares available.
Well, I shared the .STL so you can print it on your own! Feel free to modify and improve on it, or leave your comments below how can we improve it!
