7.3 Matrix Leveling (9-Point Compensation)

Tiertime Matrix Leveling can effectively reduce the adverse effects of tilt and uneven

surface of build platform. The leveling will not affect the print's dimensional

accuracy in contrary to other leveling methods. Its leveling mechanism is to first

measure the platform heights at 9 different points and then use the values to

generate a compensating raft that provides a flat and leveled build surface. Then

the object is print onto the raft for best print quality and platform adhesion.

The Leveling process could done automatically or manually on UP300D.

1. Platform may be tilted

and print surface may be

uneven (may not be visible

in real situation). Platform

height at 9 different points

are measured (arrows) by

automatic probe or

manually with paper.

2. A compensating raft is

laid onto the platform to

build a flat and leveled

surface. The amount of

compensation depends on

the result of the previous

measurement.

3. Object is printed on the

raft. Note object’s bottom

is flat and horizontal in

contrary to the platform’s

tilted and uneven surface.
