1. Preface
I.1 Introduction
The JGAURORA A-4 User Guide is designed for the A-4 users to start their printing journey with JGAURORA A-4.
Even if you are familiar with earlier JGAURORA machines or 3D printing technology, we still recommend that you
read through this guide, as there is lots of important information about the A-4 for you to get a better 3D experience.
1.2 Security matters
1) During printing, the temperature of nozzle part can be up to 250
℃
. To ensure safety, it is forbidden to touch
the nozzle and build plate directly with hand.
2) during the running of the machine, it is forbidden to extend the hand into the machine to prevent the clip.
3) Always use the A-4 with a properly grounded outlet. Do not modify A-4 plug.
4) When the A-4 continuously work over 96 hours, it should be stop for 1-3 hours to restart.
5) Do not remove the models with force , and we recommend that you should wear protective glasses.
1.3 Filament requirements
Do not abuse the filament. Please make sure you use the JGAURORA filament or the filament from the brands
accepted by JGAURORA. If you won’t use the A-4 in a long time, to avoid damp and affect print quality, you should
remove the filament from the A-4 and sealed it. At the same time, to avoid filament knot, we should make its leading
end fixed into the hole of filament tray.
All polymers degrade with time. Do not unpack until filament is needed. Filament should be stored at room
temperature:15-30
℃
and in dry conditions.
1.4 Environmental requirements
The printing temperature should between 5~40
℃
, humidity: 20%~50%, only in this range can the 3D printer
work normally.
