1．Overview
1.1 Machine Overview
IEMAI high-performance 3D printer MAGIC-HT-L is a 3D printing device based on the principle
of fused filament deposition (FFF) technology, with a printing temperature of up to 450°C, a hot bed
temperature of 150°C, and a chamber temperature of 90°C. It supports most polymer 3D printing
materials on the market, including PEEK, PEKK, PPSU, PEI 1010/ 9085 and other high-performance
materials, nylon, PC, ABS, PETG, ASA, TPU and other engineering materials, PLA class of
general-purpose materials, as well as composite reinforcement materials of the above materials
(carbon fiber, glass fiber, flame retardant, anti-static, etc.).
MAGIC-H- L is equipped with dual print heads that can support the printing of support materials,
including water-soluble material PVA, limonene-soluble material HIPS, easy-peel support material
and high-temperature resistant support material. Our modular design, such as the printhead and the
platform, can be disassembled easily, creating conditions for easy maintenance.

4. Print Operation
4.1 Use of The Printing Platform
Step 1
1.The picture shows 4 fixing clips for
fixing the building platform
2.Platform is initially leveled before
shipment
3.If nozzle is at the right distance
from platform when it first returns
to zero，A4 paper distance.
4.If first layer is printed successfully,
subsequent leveling steps will not
be necessary.
Step 2
1.If the first time to return to zero
2.The nozzle is found to be close to
or remote from the platform
3.By adjusting the four butterfly nuts
below the platform to build the
platform initially level.
Step 3
1.Manually control the Z axis to
make the platform rise, when the
nozzle and platform spacing is
0.3-0.5mm, stop rising
2.Double-headed nozzle and
platform spacing should be the
same, if the spacing is not consistent
3.Please refer to step 6.5 for nozzle
height adjustment
Step 4

2.The top wire moves upward and
touches the limit stop
3.When you hear the machine "drop"
beep
4.It means the limit is working, stop
the rotation
Step 5
1.Move the print head by pushing it
with your hand
2.So that the print head does not
touch the platform on all sides
3.and leave a gap of 0.3-0.5 mm
4.Ensure that the nozzle is at the
same distance from the front and
rear of the platform
