Many people into 3D printing?

oversize, Aug 11, 5:55pm
I have just got a 3D printer and I am loving it.
started with just general created by other people prints.
but have done some of my own now and it's great fun.

Well, can't think of stuff I need to 'print' rather than just visiting the $2 shop ?

oversize, Aug 11, 6:13pm
I made some cogs for a 50 year old model train that you can't get from a $2 shop lol

nice_lady, Aug 11, 6:25pm
Oh well done. How did you generate a design ? Did you copy some existing ones ?

oversize, Aug 11, 7:14pm
no I used tinkercad and the measurements from the cogs i had to replace.
this may not make much sense but made insulators for marklin M tracks as well to replace some broken ones I had. no chance of replacing those nowdays.

nice_lady, Aug 11, 7:25pm
Ok. What materials does the printer use?

ianab, Aug 11, 7:40pm
Plastic that's at least similar to the original material. It's not rocket science or "life dependant" stuff. If the new gears crap out in 20 years time, that's just the way the cog crumbles.

Those old train sets are collectors items these days, but the 50 year old plastic will be falling apart. If you can reverse engineer some parts with a home printer, that's a valid reason to have one.

50 year old broken train set VS 50 year old working train set?

There are different types of plastic. I have been using PLA on the basis that is what the printer come with :/

black-heart, Aug 13, 12:06pm
I used PLA and ABS, but as nice_lady points out they aren't for everyone, annoying issues with sticking, or misprints, and few have a real use for making small plastic items, or the patience to learn 3d modelling.

I am so glad I finally brought one. been wanting to for ages and I am getting a lot of use out of it.
the one on the left is an original track insulator, the one on the right is one I created and printed on the 3d printer. it is a perfect fit and I have repaired 3 tracks so far.

Nice your enjoying it. I've been thinking of getting one for a few years to make specialist parts for my radio controlled planes. I'm always breaking wing struts on my biplanes! But I've been put off by imperfect prints and how slow they print. Also time to learn the CAD software. I'll have a look at tinkercad.

I have also been making scenery props for the train set up also. (yes I know men never grow up) lol
I have not had a lot of failures but some need cleaning up. I have been learning that sometimes re-orienting the print can give better results.

Guys at work 3D print corn starch patterns and use them to have brass fittings cast. Or any other metal. Internal threads come out very well.
The white pattern is corn starch. The brass is what we are trying to make (once all the patterns are made). The patterns get destroyed by the casting process.

That is really neat. nice to see other ways of working with the 3d printing

gsimpson, Aug 24, 7:27pm
Have been tempted to get one to make scale RC planes. At least one can remake broken parts.
Like these for example

gsimpson, Aug 24, 7:30pm
I already get parts made by emailing CAD drawings to water cut and laser cut suppliers for my bike parts. The idea of getting castings made too is appealing.
I use draftsight CAD

oversize, Aug 26, 10:26am
I would think your current process would be more precise. but for prototype testing the 3d printer may be easier. what is the cost with getting the water cutting done?

I have one and while it was cheap, I think it prints better than what some others do. Easy to do something instead of going to buy something. Today i wanted a holder for my phone with Charging cable held in bottom so printed one

oversize, Sep 14, 11:11pm
what printer do you use shall? I have a monoprice mini v2.
