We will continue exploring the
impact that 3D printing has had on our hobby
in this hands on clinic. We will
design a small part (large building would
take too long to print). After you
have designed it we will spend the next 4
days printing it out. Bring your
laptop and have the 3D Builder application
from Microsoft downloaded on it. If
you have problems with the application, we
will help you with it before the clinic
starts. If we do not get it printed
before the convention closes, I will bring
your design home and print it out.
This should be a unique experience for the
clinic. Looking forward to seeing as
many of you in Cleveland as possible.
Charles Bartel, BTOC President
For those of you reading this introduction, let me tell you a bit about myself
and the rationale for putting together a series of articles which I hope might
get some of you seriously thinking about exploring 3D printing as a way to
enhance your garden railroad.

I started as a production engineer
with a background in circuit development for
a variety of products from fish finders to
fighter aircraft radars.
At Moog I was exposed to lots of
industrial environments and had the
opportunity to see many railroad activities
around these plants as well as in the local
communities that I visited.
These trips filled my head with “what
ifs” on duplicating some of the things I saw
for a model railroad (not yet into G scale

My hobby interested
started back in 1944/45 when my grandfather
gave me a prewar Lionel train set.
For 16 years this was my hobby,
putting together Plasticville buildings.
I cut up outdoor Christmas lights to
light these house up (and in a few cases,
melted them down!).
I learn to wire a layout with sidings
and do block control so that I could have
more than one engine on the layout.
When married, my wife bought me an HO
set which then became my primary interest

As an engineer I was
constantly looking at tools to advance my

rose to the top of my interest.
One was the small CNC machines for
cutting out wood with thickness for making
walls in HO buildings.
I finally purchased one, but for the
time being it sits in the hobby room
The other was 3D printing.
