This year I will post Pinhole Images on site above and I think we have a couple threads on this forum

Mr Tin Can, I will try and send you a reminder. It’s a fun event and I bet it will be very popular this year. Just an idea, you should make a pinhole camera out of a tin can. :)

Thanks Roger!
My first LF image made 21 years ago by A Tin Can Pinhole. I think I posted this recently...
A selfie made during a Darkroom college class, which got me back on the film track, then stuck on Digi until I got here on this forum, 2011.

Those look like injection moulded parts to me, not 3D printed. (Unless you have VERY different 3D printing tools from what the rest of the world uses)
There are many materials for making cameras, such as metal, wood, plastic and carbon fiber, and there are various processing methods. In recent years, 3D printing has been widely used.Quote:

We wanted a light and easy 8x10 camera, so we didn't choose wood or metal, which is solid but heavy. Finally, we chose composite plastic for 3D printing.
If it is a large-scale project, we will not choose 3D printing. In fact, 3D printing takes more time and its single piece cost is higher.
We like to interact with friends and hope that more friends can participate in the discussion.
Thank！
Injection molding would take a huge scale up (in product numbers) to make it financially feasible. CNC would actually be somewhat more cost effective with slightly smaller numbers...but I think that for the numbers you'd likely be dealing with, and considering the simplicity of your design...your composite 3D process makes perfect sense.
It's like me. It's like a trick magic. I always remember the date of pinhole day before it comes, but always forget it at that day.Quote:

It was inconceivable 21 years ago that Tin was so young.Quote:

3D printing also has precision. Generally, the precision of small machines is not too high, only small parts can be printed, and the printing traces are relatively obvious, showing rough workmanship. The processing factory we entrust is specialized in producing all kinds of plastic samples. For their equipment, it's not difficult to print our camera, so our finished products can be so excellent.Quote:
