I looked at it recently - I was interested in the possibility of making small parts for repair/conversion. As far as I can tell, the quality is still not there and if I were dead set on going into it I'd still consider a tabletop milling machine first, and hobbyist CNC machine second.

I predict Aldi or Lidl will have 3d printers in store by 2017

hello ,

it s a very good idea to resurrect this post

i'm interested in this process

You are probably correct but I think that budget priced hi-res ABS printers will take a bit more time.

You know this thread about 3D printing - with some experiences, I think Goldmark has used his printer now too:

Jure, you have in Zagreb firm HG Spot where you can have 3D item printed, and also you can buy 3D printer and filaments

Hi colleagues,
I''ve been quite busy since past February, (just after retirement) pushing all the pending housekeeping jobs that were waiting in the queue. So not too much time for photography, forums, internet, etc.
Now I'm still busy, but with some targets reached, I'm opening some holes in my agenda to get back to some photography.
One of the things I've been keeping ongoing has been my 3D printing projects. I've built two Powercode printers. I use one of them for PLA printing and the other for ABS. These printers come from the RepRap movement. They are an evolution of Josef Prusa's Prusa-I3. I'm also in the process of building a Delta printer loosely based on the RichRap 3DR. Delta printers have some advantages (faster) but they do need finer adjustments. I think they could be useful for lenses and adapters because their cylindrical shape.
I'm also in the process of learning CAD programs to build the models. I started with TinkerCAD, and later on started to learn FreeCAD, Sketchup and SCAD.
By now and regarding photography I can just print some 3D lens caps. I've tried some adapters (with little success). I need a deeper CAD knowledge, CAD design is very time consuming and quite difficult. It needs lots of practice.
Hope to drop by more often from now on.
Kind regards.
Jes.

Tell us more Jes, and be sure to keep us informed of your progress, and even your failures. This is a process that is as fascinating as it is useful and I'm sure I'm not the only one that wants to explore the possibilities.

For sure I´ll do. I disregarded this technology a few years ago, because the poor results at that time. It was a big mistake from my side. Now I am far behind and needing a considerable effort to get up to date...

I've been hearing about people using a 3D printer to print out a mount.

This sounds incredible, especially for lenses that use hard to find adapters even if they exist.

Does anyone know where they get the cad files for this purpose?

Sounds like a great solution for small runs for rare lenses.


Most commercial 3D printers of today have very poor resolution and surface quality, which can seriously impact your images for wider focal lengths. This may change in the future, but I wouldn't 3D print a mount yet. Stick with CNC machined mounts ...

I have a lot of experience with 3D printer and adapters. And can say: it works

Here a thread (only German, but with a lot of pictures): http://www.digicamclub.de/showthread.php?t=21030

Perhaps a picture of the adapter?

I could use some simple NEX bayonet plates, like the ones that are on the back of the standard 18-55 lens to mount some rangefinder lenses directly on the plate for use on NEX/A7.

I had one form a broken lens, and used it to mount a Canonet 28 40mm lens. See here: http://forum.mflenses.com/canon-40mm-f-2-8-rf-lens-t73332,highlight,%2Bcanon+%2B40mm.html

So if anybody knows where to find a print-file i'd be very, very happy!!

Interesting idea. From my own experiences, 3D printed stuff can be rough and inaccurate, strength might also be a big problem. But there might be some more advanced materials .
Would be really interesting if someone can figure out a reliable material+machine.

2020 I was 3 years out

I have bought a couple of adaptors printed in plastic and find them rough and inaccurate requiriing lots of filing and sanding to get them to work. Threads don't come out well at all. This in 2021-2022

Fast forward to 2021
I have made a couple of those in FDM printers (filament). Threads are not perfect but they work fine for a quick proof of concept.
It has allowed me to test lenses from several mounts in a PK camera but adapters are good for 1use only and I prefer to make M42 adapters instead of bayonet for safety.

However I had access to a resin 3d printer (SLA) to print a 39mm to M42 (enlarger lens to bellows) adapter and the result was much better. Threads are smooth and the overall material is rigid and strong.
It can be used several times IMHO

Those printers are not crazy expensive anymore and is always good having a friend that has one

Usually I add Chinese Canon EF or Sony FE alu bayonet pieces to my 3D designs Lightest ones are the reverse rings. The filter thread side can be easily glued into designed grooves of the 3D printed adapters. Other wise 4 or 5 screws are used to bind them to the 3D printed part, mainly if the bayonet + adapter has to be removed again. The same for M42 thread, I start with 3D printing a 39 thread on the part and add a 39>42mm metal screw adapter. Better thread, less wear in use. Small screw threads are made with small taps that fit in holes spared in the 3D designs. like for securing an alu bayonet to the printed part.

https://www.dpreview.com/forums/thread/4381799?page=3

One exception are my Minolta MD to Canon EF adapter rings. Kind of bayonet sleeve; female MD bayonet inside, male Canon EF bayonet outside. The MD flange itself falls against the EF camera mount flange (in my case either a Sigma MC-11 or Metabones IV adapter). As the register distance of the MD mount is 0,5mm shorter the lens has to be calibrated for infinity though.

What I find incredibly easy and satisfying is printing lens caps in the 3D printer, for vintage cameras (e.g agfas) and even for hard to find lens caps (e.g fisheye takumar)

With some practice I have even found ways to add monograms or logos to the caps, or to make those "bokeh" lenscaps that were fashionable with the millenial crowd.

Now I have a 3D printer I will probably do lens caps going up in something like 2mm increments. Often need odd-sized stuff.

Lens caps for certain bulbous lenses would be an interesting idea like you say. Trouble is I probably don't own those problematic lenses, but not beyond asking someone for measurements.

I found a 2nd Fisheye Takumar 17/4 but the front cap was missing.
I made a cap using the push-on lens cap customizer
and placed it here https://www.thingiverse.com/thing:5769709

Tht customizer is great, especially if you can use scad as depth, diameter, thickness, etc can be easily adjusted.
