Make Something Wonderful

QUICK START GUIDE
| Enclosure

Welcome to
the world
of making
Three years ago, when we were designing
the Snapmaker Original, we broke the
rules of traditional desktop 3D printers and
created the first modular 3-in-1 3D printer
on the market. At first, The Verge and a lot
of other reviewers doubted that “Snapmaker
is an upcoming Kickstarter project with a
lofty goal: to be the holy trinity for at-home
makers by using detachable modules to
convert between a 3D printer, a CNC carver,
and a laser engraver,” and “At the price
that Snapmaker is selling, it’s possible the
whole thing is too good to be true.” We
knew people had a lot of uncertainty about
our project and were hesitant to back us
because of the complexity of designing
and making such a product. Despite all the
doubts, we worked hard on pushing the
boundaries of possibility and we eventually
made the impossible possible. Not only did
we fulfill all the rewards, but we also sold
over 10,000 units all over the world in 2018.
And in 2019, we launched the Snapmaker
2.0. We went beyond our limits once again.
Our goal is to build a system behind our
modular 3D printers and give you the best
maker tools that can work for all your
projects. As creatives we all desire to make
something wonderful and creativity makes
us feel alive. The Snapmaker 2.0 will help
you turn your ideas into reality. This quick
start guide will guide you through your maker
journey. Congratulations on becoming part
of the Snapmaker community! Thousands
of people like you are using the Snapmaker
to explore, make, and share in the world
of making. We are strong believers that
wonderful things will happen when creative
minds meet the ideal tools. Have fun making
and see you out there!
Team Snapmaker
Make Something Wonderful

This machine is built for innovators. Our goal is to assist
you to make the world a better place with a machine we
built with love. The difference could be something as
small as a Christmas gift, or something as ambitious as
exploring unknown territories of our mankind. Dream big
and make it happen.
Happy Making
Snapmaker is not only a 3D printer, but also a powerful
machine that you can modify with all kinds of addons. You
can equip your Snapmaker with an enclosure to protect
you and your family from laser and dirt particles. New
addons are coming soon with more exciting features.
Please stay tuned.
