Snapmaker A350 User manual

Welcome to
the world
of making
Three years ago, when we were designing
Snapmaker Original, we broke the rules on
desktop 3D printers, which were limited
to single function, and created the first
modular 3-in-1 3D printer on the market.
At that time, The Verge and a lot of people
were watching us, thinking 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 doubting that
“At the price that Snapmaker is selling, it’s
possible the whole thing is too good to be
true.” We knew there would be a lot of buzz
about our project and people were hesitant
to back us because of the low possibility of
delivery. Despite all this, we worked hard on
testing the boundaries of all the possibilities
by going beyond them. Finally, we made the
impossible possible. We not only fulfilled all
rewards, but also sold over 10,000 units all
over the world in 2018.
In 2019, we launched Snapmaker 2.0
products. Again, we went beyond ourselves.
We are building a system behind our
modular 3D printers. Our goal is to give you
the best maker tools that work for all your
projects.
We all desire to make something wonderful.
Creativity makes us feel alive. With
Snapmaker, you will make your idea a reality
soon. This book will help you to start your
maker journey and take you from building
your own 3D Printer/Laser Cutter/CNC
Carver to making your first creations using
all these tools.
Now you are part of the Snapmaker
community! You are going to make incredible
things happen. Thousands of people like you
are using the Snapmaker to explore, make,
and share in the world of making. We also
love to discuss with you about your project
ideas and what you’ve made. We believe that
wonderful things will happen when creative
minds meet the ideal tool. Have fun making!
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.

- You notice unusual light or an unusual sound coming from this machine that was 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 machine 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 tool is a class 4 laser. You are only allowed to operate the laser tool if you have a sufficient
specialized and safety knowledge: You must know the physical properties as well as the biological
effects of laser radiation, the legal bases and rules of technology, the laser classes and their dangers, the
implementation of safety measures.
- Operate the machine with an enclosure covered and wear the Laser Safety Goggles.
- Never expose yourself to the laser beam. Proper use and care of the laser tool are essential to safe operation.
- Operate the laser tool when it is exhausted to the outdoors or through an air filter. The melting of some
materials may release toxic fumes.
- Always unplug the machine before performing maintenance or modifications.
- Remove any reflective material from the work area underneath the laser module. Reflective material can
cause uncontrolled scattered radiation.
CNC Safety
- Age Recommendation: For experienced users and users age 18 and above.
- Put the machine into an enclosure 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 machine 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 tool, then work to free the jammed material.
- Do not touch the bit or collet after use. After usage, the bit and collet are too hot to be touched with bare hands.
- Some dust created by CNC carving and cutting contains chemicals known to cause cancer or other
reproductive harm. To reduce your exposure to these chemicals: work in a well-ventilated area and work with
safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
