3D Printing Sig

[Stephen Rainsbury]

I have discussed this with Julian, so would anybody else be interested in forming a 3D Printing SIG?

Apart from the exchange of ideas, I think we could start a library of original .stl and CAD files of not only rolling stock but scenic items and tools such as back to back gauges.

PM me if interested please.

[Ian McAulay]

I'll PM you as well if you like, Stephen, but a public reply seems appropriate.

Yes, I would be very interested. I'm the joint owner of an Elegoo Mars Plus resin printer which was a recent (January) shared birthday present to me and a modelling friend (a present both to and from each other!).

I'm quite experienced at the computer end of 3d modelling, which was quite a large part of my job before I retired, but very much a newbie in printing. I've probably got something to offer in originating/modifying/editing 3d models, but lots to learn in the practicalities of getting successful prints from them.

Hi Ian, yes maybe an introduction here is appropriate.

I have very little background either, but I have an ender 3 filament printer, which I bought in the Amazon sale last year, and a Photon Mono resin printer which my old school gave me as a retirement present (after we added some cash).

I am happy with the Ender 3 most of the time, although I find t a bit coarse for detailed models, but constantly disappointed with the results of the resin one and have yet to print something I wanted to use.

I had never used a 3D Cad package but after encouragement from another well known NG forum I started working through the FreeCAD tutorials and am starring to make some headway there although I suspect I could use it far more efficiently.

I would like to compare notes with others, to help improve our results, discuss subjects such as keeping the cost down and what do you do about cleaning and curing resin models as there seem to be as many opinions on that as their are people. 

I would also like to have an index to useful NG .STL on places like Thingiverse and somewhere to keep our own work, such as this engine shed which I am working on.

Stephen, I would be interested in joining as I've done a few 3d printed bits for my layout. I use an Anycubic Photon though could do with something a bit bigger. I also do my own drawings though I must admit I can't get my head round compound curves when doing roof profiles. The attached photo shows in the foreground left, 3 cabs for the Roco HF110 to make it look a bit more British and on the right Manning Wardle works numbers 1919 - 1920 which were supplied to the Futwah & Islampur railway in India. In the back right are some Crich Mineral railway wagons and a 5 window Kitson Steam tram. I also done various other tramway vehicles as well.

Please let me join too!

I've been using an excellent Ukrainian 'Klema' Fused Deposition Modelling printer for a few years but I had to leave it behind.  Not sure what I'll buy when I get to Canada but I will be back in the game before long.  Also I was outsourcing and will outsource designs for higher-quality printing and would love to learn about the best options for that.

A Society print file library sounds like a superb idea (that I wish I had thought of).  I don't know yet what I would contribute but what I would be looking for would be pleasing 009 wagon chassis.

Looking forward to the first meeting.

[Robin Webster]

I like the Indian Futwa & Islampur model. What chassis has it been designed for?

[Stephen Rainsbury]

Julian has agreed to the SIG, what would be the best time for people to meet up on zoom, evening, afternoon, weekends?
I suggest that for the first meeting we introduce ourselves and mention our facilties,  then discuss a specific topic  such as washing and curing, any other ideas?

[Tom Haythornthwaite]

Some 3D Special Interest Group discussion ideas (including those mentioned so far):

print washing and curing
Society print file library
3D design software and techniques
outsourced printing - service, quality, pricing....
3D printers
3D printing material (which depends on printer type, of course)

There must be many more.

All following introductions, of course.

[Stephen Rainsbury]

Brilliant, and I would like to have a special one for non sig members to explain what it's all about too.
When is good fir you?

[Tom Haythornthwaite]

Me?  Evenings or weekends.

[Ian McAulay]

I'm retired, so I can fit in with most times.

[Stephen Rainsbury]

Wednesday 1st June at 7:30 Ok for everybody?

Stephen

[Jonathan Mead]

I would be interested in joining this SIG. I have been designing and printing for a while now, although in 16mm scale for my garden railway, and I'm just getting into 009 for the wet winter evenings! I've got an Elegoo Mars Pro resin printer and a Purse i3MK3S+ FDM printer, and use OnShape for design.

[Stephen Rainsbury]

Great News Julian, we have our own section of the forum now, and are just agreeing a date for our first meeting, provisional 2nd of June at 19:30.
