3D printing and design guide.

CAD
If you want to get a 3D printer, the first thing you need to do
is learn CAD. Although there are some STL files available
online, you really need to be able to draw your own designs.
Solidworks is the industry standard but very expensive. Fusion
360 is what i use and is free for hobby use. Dont be put off the
first time you open Fusion, start small, a simple cube or
cylinder is a good starting point. Most of my first designs were
only various boxs joined together. I taught myself by watching
the likes of Lars Christensen on Youtube.

In one year i went from this,-

Dont be too ambitious, take small steps. The more you practice,
the sooner you will remember all the various commands.
3D Printers
The two main types of 3D printers for the hobbyist are, filament
prinnters (FDM) and resin printers (SLA).
Filament printers are great for larger projects and the prints
are more robust.
Resin printers can print very fine details but can be brittle.
FDM
I started with a Creality CR10S, in hindsight i should have got
a smaller printer as it was far too big for anything i was
printing.
I have since bought a smaller Anycubic i3 Mega S. This has a
print volume of 210x210x205 which is still more than enough for
the things i make. It is a more refined printer over the
Creality and the print quality is excellent.

SLA
Because i make 1:32 models i found the FDM printers could not
print the fine details i required so along came an Anycubic
Photon Mono.

As i have stated, resin printers are great for detail but they
are so much more work. You pour liquid resin into a vat that is
then cured by ultra violet light into the design you require.
Once the print is finished you then need to wash off all the
uncured resin with Isopropal alcohol before fully curing it with
more UV light.
If you are prepared for the extra work the results can be
excellent.

P.S. sorry for any bad spelling or grammor, being dyslexic
dosent help!

Slicer Programmes
To convert a CAD drawing into something you 3D printer can use
you will require a slicer programme. Simply it slices your
design into thin layers so that they can be printed layar by
layer.
My programme of choice is Ultimaker Cura. The following is some
of the settings i use.
Nozzle size 0.4mm.
Layer height 0.1mm.
Wall thickness 1.2mm.
Infill, 10% and up depending on the size and usage of the part.
Material, Esun PLA+
Print temp, 210*.
Inital printing temp 225*.
Build plate temp 60*
If there is any other settings you would like to know just ask.

This is useful, thanks Noel.
It just so happens that our Men in Sheds shed had a new printer
donated at the weekend, so I am just starting to find my way in
this new area of making things.

Nice printer, haven't heard of the Robox range before. Quite a
price tag !

I think they are designed for schools, but the company that
sells them offered it, along with some support to help us with
dust extraction at the Shed. Hopefully it's bulletproof it will
need to be!

Thanks for the input.
I have just got a Ender 3 S1 Pro filament printer.
I have got an account on Fusion for Hobby use. Free Version.
Just starting to get to grips with it.
Is the first post on where to look for tutorials on YouTube
still the best to go to?
Many Thanks

I have "inherited a Prusa from engineer son, he installed
"Onshape" for me yesterday, it seems pretty intuitive and
doesn't need computer space as it apparently uses their server.
Downside is that it's automatically shared I understand.

With a friend, who is further advanced than myself in starting a
build, I am helping him to initially create a 1/10th model of
his CycleKart. I say model, as it will be more of a design and
layout aid, rather than a full rendition of his proposed Kart.
People with a printer will know that in the slicer program you
can set the scale. So if you find full size CAD models. It is
not a problem.
The initial need was to find some Pit Bike wheels/tyres. I came
across such a model on a USA site.
HTML https://www.cyclekartclub.com/forum/cyclekart-tech-forum.2/pit-bike-17-wheels-cad-drawings-analysis.68720/<br
/> Too complicated to 3D print, as essentially too detailed.
I also found CAD for a GX200 engine.
HTML https://grabcad.com/library/honda-gx200
Not essential as these things could be just a block for such a
layout model. Bit of fun anyway.
