Make Something Wonderful

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 that “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.

Welcome to
the World

of Making

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 idea into reality. This Quick Start
Guide will guide you through your maker
journey and take you from building your own

3D Printer, Laser Cutter, and CNC Carver to
making your first creations utilizing all these
modules. 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 believe that wonderful things
will happen when creative minds meet the
ideal tools. Have fun making and see you in
our community!

Team Snapmaker

Happy Making

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 project could be as small as a
Christmas gift, or as ambitious as exploring unknown
territories of our mankind. Dream big and make it happen.

Modular System

Snapmaker is not only a 3D printer, but also a powerful
machine that you can customize with addons. You can
equip your Snapmaker with an enclosure to protect
you and your family from laser and contaminants. New
addons are coming soon with more exciting features.
Please stay tuned.

- Do not expose this machine to rain or wet conditions.

- Keep children and bystanders away while operating this machine. It requires the supervision and

assistance of an adult when children use this machine.

- Stay alert, watch what you are doing and use common sense when operating this machine. Do not use this

machine while you are tired or under the influence of drugs, alcohol or medication.

- Do not reach inside the machine or touch the moving parts while the machine is still in operation, as it may

Quick Start Guide | 3

Before You Start

Turn off the machine immediately and stop using this product, if any of the following occurs:

- You smell burning in this machine at any point.

- The machine stops working unexpectedly.

- You see any damage to the interior components of this machine.

- Unusual lights, sparks, or sounds come out of this machine which were not occurring previously.

3D Printing Safety

- Do not touch the nozzle, Print Sheet and Heated Bed when the machine is printing or heating.

- Always unplug the power cord from the electrical outlet before performing maintenance or modifications.

- Set up the printer in a well-ventilated place when printing with ABS. The melting of some materials may

release toxic fumes.

Laser Safety

- The Laser Module is a class 4 laser product. You should operate the Laser Module only if you have

sufficient knowledge of (i) the physical properties of laser radiation, (ii) Laser Hazard Classes and

associated health implications, and (iii) safety measures.

- This laser product should be used exclusively for recreational purposes.

- Never expose yourself to the laser beam. Proper use and care of the Laser Module are essential to safe

operation.

- Operate the Laser Module in a well-ventilated place or with an air filter. The melting of some materials may

release toxic fumes.

- Always unplug the power cord from the electrical outlet before performing maintenance or modifications.

- Remove any reflective material from the work area underneath the Laser Module, as it can cause

scattered radiation.

- Operate the machine with an enclosure covered and wear the Laser Safety Goggles.

The laser safety goggles block direct, reflected, and scattered laser

beams and radiation with the wavelength between 190 and 540

nanometers (nm) and the optical density higher than 6 (OD 6+), from

entering your eyes, thus providing protection while you operate with

the Laser Module.

The lenses might be burned when subjected to high energy laser

beams, and if this happens, you must stop using the damaged

goggles and use a new pair. Also, due to the qualities of polycarbonate

which is used to synthesize the lenses, you should use PH neutral

detergent or water to clean them and avoid scraping them.

CNC Safety

- For experienced users and users aged 18 and above.

- Operate the machine with an enclosure covered and wear the CNC Safety Goggles.

- Always have the material securely clamped. Never attempt to hold the workpiece with your hands

throughout the CNC carving process.

- Always unplug the power cord from the electrical outlet before performing maintenance or modifications.

- If the bit or workpiece become jammed or bogged down, turn off the machine immediately. Wait for all

moving parts to stop and unplug the cable, and then work to free the jammed material.

- -Do not touch the bit or collet after use, as doing so can cause burn hazards.

- Discharge from CNC carving and cutting contains chemicals known to cause cancer and harm to reproductive

system. To reduce exposure, operate the CNC Module in a well-ventilated place and take safety precautions

such as wearing an N-95 mask.
