........ - no need to level the bed.
Does it have auto bed levelling?

Rik
It effectively self levels. The way it does this is by using a raft to create a level bed for every print. In practice I have been able to print without using a raft and without any levelling issues. Having said that I usually use a raft for large prints in ABS. I know it uses some filament to keep creating a raft for each print - but there is no need to level the bed.

Trevor
Nifty!

I am now down to the business end of my search and the Ender3 V2 is now the front runner and will most likely be ordered shortly when they become available in Aust.

To expand on my original use for a 3D printer, my wife made a comment along the line of "could you use it to make buildings?" that got me thinking so I went searching for examples of what others had done (why reinvent the wheel) and came across these tutorials of how to do brick wall using tinkercad which I have downloaded and had a "tinker" with.

They are off this site that has electronics as well so a bit of an attraction for me.

That sounds as though you haven't seen Trevor's threads on his complete buildings? ( and/or bogie coaches) plus Rik, Steve and I, and others, have written about printing wagons either complete or as 'kits', and various components fro vehicles and accessories. The possible uses are really mostly limited by an individuals imagination and drawing skills.

Apart from track and groundwork and people everything in this photo was 3 D printed, and designed my me in Sketchup make 2016.

That includes the loco, wagons, and the bridge.

As Peter says - there is loads of information in the 3 D printing section!

I did look at the 3D printing section but found that I may be out of my league with what is in there till I get familiar with Tinkercad and a real live 3D printer.

I have a Linux based computer in my shed so "Tinkercad" will not run on it the alternative evidently is "Blender" has any one used it?

I do have a windows laptop that I can use if it does not work out.

You will find Blender very difficult to use. Well I did. Look at my thread on making individual resin printed people, to get an idea of how complicated it is. So that isn't where I would start your particular journey!

Tinkercad isn't one I have used but there are quite a few modellers on this forum using it successfully to create impressive models.

Since you have started to learn to use it stick with it - it will take you where you want to go as far as I can see.

Which printer - choose whatever you fancy - particularly bearing in mind local availability, and the ability to buy spare parts. It is like everything else - you start with something that is low cost in case it doesn't develop the way you think it will. Later you might want something more expensive!

You will only get so far until you can actually print things out.

Don't even think about using Blender, certainly not at this stage. The only person I know who has any sort of real working knowledge of it is "Metalmuncher" but I don't think even he uses it for the basic drawing of a discrete object, it is more for manipulating things produced in other software. It is professionally used to produce sophisticated CGI animations, which gives some idea of it's sophisication and complexity and lack of intuitive functions.
However I should say that Trevor and I have used it succesfully to pose 3d printable figures created in 'Makehuman', following a tutorial video from Metalmuncher.

Like Trevor, I use Sketchup, I tried Tinkercad and didn't get on with it.

Advice noted "Blender" now out of consideration.

If you were to go for sketch up you need to find a copy of the 2016 version. That is the last one which was a stand alone app which was located on your computer. After that it became internet based, and lost functionality. That online version seems to have been abandoned.

I am 'tinkering' with Tinkercad (used by Rik) and have found out that it is web based and this morning I successfully logged in to it on my linux computer.
Evidently as it is web based and I am using Firefox it works.
Digging deeper the information I was working off was out dated like a lot of the reviews for printers I found.

So for the moment I will keep using Tinkercad and take small steps towards more functional CAD programs.

Thanks to you all for the help and advice I am sure there will other requests for help in the future.

I am not sure you will need anything more functionable than Tinkercad. The things I have done with it never cease to amaze me. From a 16mm scale working loco and tender, including wheels, sand pots, linkages, body, chassis etc etc, to a piece that I reproduced for my wife's wheelchair as part of the swing out for the leg wore away and this was a great replacement for it.

My transition to the dark side is now complete, I just bought a Creality Ender3 V2 3D printer.

I have started "tinkering" with Tinkercad and successfully imported an STL file from Thingaverse and following a tutorial have the start of a brick wall.

So the world of 3D printing is now mine to control :twisted: :twisted: :roll:

Nope... The world of 3D printing is now in control of you! :lol: :lol: - It IS addictive.

Well done though. :D
