Do not insert metal objects, flammable
objects, or any other foreign object into
interior areas other than the top of the
table. Also, do not place water or other
liquids on any area, including the table.
Doing so may cause fire.
In such cases, there is danger of external emission
of Class 2 laser light. Staring at externally emitted
laser light may cause eye injury.
Securely fasten the object to be scanned
to the table so that it does not slip or topple
over.
Lifting and carrying are operations that
must be carried out by two persons, by
grasping the bottom of the machine.
Failing to do so may result in injury.
The table rotates during scanning. Tipover or
contact by the scan object may cause damage.
Scan-object damage is not covered by warranty.
Do not attempt to scan objects that are
highly reflective or refractive, such as
mirrors, prisms, or lenses.
In such cases, there is danger of external emission
of Class 2 laser light. Staring at externally emitted
laser light may cause eye injury.
Important Cautions Regarding Laser Light
This machine uses a laser beam to scan objects, but dangerous laser radiation is not emitted outside the machine. It is safe to view the laser light
through the window.
However, this may not be the case if the machine is disassembled or if its cover or safety devices are broken or disabled. Please observe the
cautionary notes in this documentation and never attempt to use this machine if the machine is in an abnormal state.
The natural blink reflex protects the eye in the event that laser light from the machine directly enters the eye due to incorrect use or the like, but
staring directly into the laser beam may result in eye injury. Direct contact with the laser beam will not cause burns or fire.

ment LEDs go dark. Scanning is now possible.
Initialization may take up to about 40 seconds. If the door is opened during initialization, operation is interrupted to ensure safety.
In such cases, correct scanning cannot be performed. Switch off the power, close the door, then switch the power on again. Also,
sound that is differ from what you usually hear may be heard for several seconds during initialization, but this does not indicate
a malfunction.
Starting the computer after switching on the machine may make it impossible to perform scanning. This may occur depending
on the computer, but does not indicate a malfunction. If this happens, start the computer first, and then switch on the power to the
machine. Also, if the computer is restarted, reset the power to the machine as well.
Switching Off the Power
When the machine will not be in use for a prolonged period, unplug the power cord from the electrical outlet.
Failure to do so may result in deterioration of the insulation, leading to electrical shock, short circuit, or fire.
Hold down the Standby key for 1 second or longer.
Opening and Closing the Door
When you open the door, the Standby key flashes green. Scanning cannot be performed while in this state. Close the door, then start
scanning.
To ensure safety, an emergency stop occurs when the door is opened while scanning is in progress. Scanning cannot be resumed even after
the door is closed.

Basics of the LPX-250
1. Scanning System
The LPX-250 scans objects using laser light. It emits a spot beam onto the scan object and detects reflected light from the object with sensors. It
performs scanning as it rotates the scan object and moves the laser beam from bottom to top.

2. Suitable and Unsuitable Objects for Scanning 3. Plane Scanning
3. Plane Scanning
Features of Plane Scanning
This mode uses parallel laser beams to scan while rotating the table and laser head in synchronization. Because this mode can obtain
comparatively stable scanning results regardless of the shape of the object, you can use it as an all-purpose mode. You can use it to scan up
to six surfaces at one time (multi-plane composition).
The laser beams strike
substantially in parallel.
Multi-plane composition
Plane scanning system
(four scanning surfaces)
Mounting Orientation for the Scan Object
When the object to be scanned has areas with cavities or voids, plane scanning, which uses parallel laser beams, is effective. This is because
the laser light can easily pass through the voids. However, if the laser light is blocked by another area, it becomes impossible to determine
that the void exists. This means the direction from which the laser light is beamed is very important.
If you are scanning a doll, for instance, you can capture the voids between the legs and under the arms by aiming the laser light in the
direction shown in figure A. If the orientation in figure B is used, the laser light is blocked and so the two legs end up joined.
B
A
The laser light is emitted from the right side. This means that if your aim is to capture the void between the legs, for example, it is best to
mount the doll so that it faces right. The direction in which the laser light is incident is decided by the orientation of the scan object mounted
on the table. With multi-plane composition, this orientation is the first surface for scanning.

Part 2 Basics of the LPX-250
In general, increasing the number of scanning surfaces results in greater scanning precision with correspondingly fewer conspicuous seams.
In the example of the doll, however, only one of the five scanning surfaces can capture the voids. From the standpoint of capturing voids,
two surfaces are more effective.
Scanning surfaces: 5
4. Rotary Scanning
Features of Rotary Scanning
Scanning surfaces: 2
This mode scans the outer perimeter of the scan object while rotating the table in one direction. This is suited to scanning objects that have
relatively little unevenness and are close in shape to a sphere or cylinder, and lets you perform smooth scanning for curved surfaces.
It is more selective of the shape of the object than plane scanning, but conversely reproduces smooth curves even at relatively coarse pitches,
and also takes less time. Capturing cavities and voids in objects is more difficult than with plane scanning.
The laser beam is emitted
toward the center of the table.
Rotary scanning system
Finishing by Rescanning
If the object is highly uneven, there may be many areas that the laser light does not reach. Rotary scanning is more likely to be affected by
this than plane scanning, and may result patches that are not scanned. With rotary scanning, you can finish such areas by rescanning.
Perform rotary scanning for the entire object, then rescan only the areas you want to finish. This enables scanning with an attractive finish
even for detailed portions while smoothly reproducing the curved features of the entire object.

5. Mounted Position of the Object and the Scannable Area
The scannable area may differ slightly according to the scanning mode. The area that you can actually scan is affected by the mounted position of the
object. Also, mount the object so that it does not extend beyond the table.
Plane Scanning
Multi-plane Composition (Two to Six Scanning Surfaces)
For multi-plane composition, mount the object near the center of the table. If it is mounted at the edge of the table it will fall outside the
effective sensor area, making correct scanning impossible.

The basic principle is to mount the object to be scanned at the center of the table.All areas to be scanned must be at the table center. The area
away from the center of the base (the shaded portion in the figure) cannot be scanned correctly.

Effective Sensor Area
The area where the laser sensor detects reflected laser light is to the right of the center of the table. This is the effective sensor area. When
laser light is reflected from the area to the left of the table center, the LPX-250 decides that there is no object to scan. The surface of an object
mounted at the table center always passes within the effective sensor area, and the laser light is always reflected from the area to the right.
This effective sensor area must also be taken into account when the object has large depressions or shelf-shaped areas.

1. Getting Ready to Scan
Part 3
Basic Operation
1. Getting Ready to Scan
Selecting a Scan Object
Before you start scanning, give thought to what objects are suited to scanning.
Conditions for suitable scanning
Remedies when unsuitable
Object material and
color
Does the objects not pass light?
Is the object a bright color such as white or yellow?
Is the object of a nonglossy material?
Consider applying a white surfacer (primer).
Object size
Does the object fit on the table?
Think about whether you can break down the object
into separate parts.
Object shape
Can the object be placed on the table in a stable way? Consider using a fixing frame or clay to secure in place.
Does the object have many areas that laser light
cannot reach?
Think about whether you can break down the object
into separate parts.
Deciding on the Scanning Mode
Give thought to whether to perform scanning in the plane scan mode or the rotary scan mode. In general, it is a good idea to select rotary
scanning for objects that are nearly cylindrical and have relatively little unevenness, and plane scanning for other objects.
If an object is nearly cylindrical overall but has one or more areas that are not suited to rotary scanning (such as the handle of a coffee cup),
you may consider using rotary scanning to scan the entire object, then using rescan for finishing. For detailed information about rescanning,
go to Part 4 and refer to "3. Finishing Detailed Areas Using Rescanning."
Mounting the Scan Object
Do not insert metal objects, flammable objects, or any other foreign object into interior areas other than the top of
the table. Also, do not place water or other liquids on any area, including the table. Doing so may cause fire.
Securely fasten the object to be scanned to the table so that it does not slip or topple over. The table rotates
during scanning. Tipover or contact by the scan object may cause damage. Scan-object damage is not covered
by warranty.
Mount the scan object near the center of the table. For Rotary scanning in particular, mounting the object away from the center may make
it difficult to obtain good scanning results.
The table rotates during scanning, so secure the object in place using double-sided tape, clay, or an optionally available vise to keep the
object from falling over or slipping.

Part 3 Basic Operation
Do not touch any internal components other than the table. Doing so may result in breakdown.
Do not attempt to move the table, laser head, or any other working parts by hand. Doing so may result in breakdown.
Make sure the scan object does not extend beyond the table. The object may touch the interior of the machine, causing
breakdown or damaging the scan object.
2. Scanning Operation
Do not open the door while scanning operations are in progress. To ensure safety, an emergency stop of scanning operations
occurs. Scanning cannot be resumed even after the door is closed.
This section describes how to set the scanning conditions automatically. You can also set detailed scanning conditions manually. For more
information, see Part 4.
1. In Dr. PICZA3, click the [SCAN] button. The [Scan] dialog box
appears.
2. Click either the Plane Scanning or the Rotary Scanning button.
Scanning starts.
3. Examine the results of scanning. As required, perform finishing
by rescanning (for rotary scanning only), or modify the scanning
conditions and do scanning over from the beginning. For more
information about viewing the scanning results, refer to the fol-
lowing section, "3. Viewing the Results of Scanning." For infor-
mation about rescanning and changing the scanning conditions,
see Part 4.
Automatic Setting of Scanning Conditions
In this operation, the size of the scan object is detected and the scanning area is set automatically. The scanning pitch is also automatically
adjusted according to the size of the object. For plane scanning, the number of scan surfaces is always four.
If the object has a highly irregular shape or long, narrow protrusions, the size may not be detected correctly. If this happens, then perform
scanning using settings made manually, as described in Part 4.
Verifying the Scanning Conditions
You can check and verify the scanning conditions that were set automatically. After scanning has finished, go to the [Scan] dialog box and
click the [Make Settings and Scan] button. Here you can revise the scanning conditions and redo scanning using new conditions. For detailed
information about scanning conditions, go to Part 4 and refer to "1. Detailed Settings for Plane Scanning" and "2. Detailed Settings for Rotary
Scanning."

4. Saving Data
Saving in Dr. PICZA Format
You can save scanning results in Dr. PICZA format. In Dr. PICZA3, go to the [File] menu and click [Save As]. In addition to Dr. PICZA3,
the 3D Editor program for editing 3D data can also open files in this format.
Exporting Data
In addition to Dr. PICZAformat, you can save (export) scanning results in DXF format (3D surfaces), STL format (text or binary), or Point
Group format. These are commonly used formats, so you can make use of them to share data with other programs.
1. In Dr. PICZA3, click the [Export] button. Click the file format you want to use for exporting.
2. For STL format, select either text STL or binary STL, then click [OK]. For Point Group format, select the separator
character, then click [OK]. Select one supported by the program with which you want to share the data.
[Export] button

3. Type in the name of the file to export, then click [Save].
In addition to these, the LPX-250 also supports exporting in VRML format, 3DMF format, and (with some restrictions) IGES format. You
perform exporting in these formats using the 3D Editor program for editing 3D data.
When you export the results of multi-plane composition, a number of sets of scanning data are merged. When you view data with Dr.
PICZA3, however, to speed up the screen display time, this processing is not performed. There is nearly no difference in the display before
and after processing, but if you want to check the appearance after merging, open the scanned data in 3D Editor.

2. Detailed Settings for Rotary Scanning 3. Finishing Detailed Areas Using Rescanning
3. Finishing Detailed Areas Using Rescanning
After you have scanned an entire object, this feature rescans just one portion with changed conditions. Basic scanning should always be performed
using the best possible conditions, of course, but by using rescan to finish detailed portions you can make the data even more highly finished.
Rescanning is effective only when you used rotary scanning to perform the basic scanning.
Finishing Areas That Could Not Be Scanned
Depending on the conditions, rotary scanning may produce results like those described below. However, you can perform finishing by
using rescanning. This is a feature that lets you do scanning over again in the plane-scanning mode for the portion you want to finish.
Note that you cannot expect any benefits from rescanning in cases such as those where the shape of the object blocks the laser beam no
matter how the object is oriented.
Areas joined because the laser light does not reach
Areas with holes due to surface drop-out
1. First, use rotary scanning to scan the entire object. From this
point on, until rescanning is finished, the mounted position of
the scan object must not be moved.
2. When you have finished scanning the entire object, click the
[Scan] button. A dialog box appears.
3. Click [Rescan a different location of the shape]. The Controller
appears.

4. Hold down the SPACE key and drag to position the
area you want to rescan at the front. This makes the
front surface the direction of laser-beam emission. As
you determine the orientation, try to angle it so that
the laser light can penetrate sufficiently (or so that the
laser light passes through).
SPACE key + drag left or right
to shift the perspective.
5. Drag (without holding down any keys) to specify the
rescanning area. The direction of plane scanning is
determined by the on-screen orientation at this time.
6. You can specify more than one rescanning area. To
do this, repeat steps 4 and 5. The scanning orienta-
tions are as you specify in step 5, resulting in scan-
ning in more than one direction. (Note, however, that
the scanning pitch is identical for all directions.)
7. Enter a finer scanning pitch as required, then click
[Scan].
Drag to select the area to rescan.
This executes rescanning.
Shortcut Keys for Shifting the Perspective
You can also use the arrow keys to shift the perspective when specifying the rescanning area. Also, you can shift in parallel or zoom in or out
by holding down the CTRL key or the SHIFT key while dragging.
Specifying an Area and Rescanning
Clicking anywhere on the object after you have specified the rescanning area releases the area you specified. Also, even if you have per-
formed rescanning, you can return to the state before rescanning by using the [Undo] button.
[Undo] button
Rescanning and the Scanning Pitch
When you are creating a void, as in the example of the coffee cup, it may be a good idea to make the scanning pitch somewhat finer. When you
want to a void or cavity in detail, it is effective to make the scanning-pitch values smaller than the size of the void.

3. Finishing Detailed Areas Using Rescanning
Scanning a Specific Area in Greater Detail
You perform coarse scanning of the entire object using rotary scanning, then rescan just the required areas at a finer pitch. This can reduce
the size of the data and also shorten the scanning times. This feature is for rescanning a portion in the rotary-scanning mode.
1. First, use rotary scanning to scan the entire object. From this
point on, until rescanning is finished, the mounted position of
the scan object must not be moved.
2. When you have finished scanning the entire object, click the
[SCAN] button. A dialog box appears.
3. Click [Rescan a portion in detail]. The Controller appears.
4. Hold down the SPACE key and drag to position the area you
want to rescan at the front.
5. Drag (without holding down any keys) to specify the rescanning
area. You can specify more than one scanning area.
6. Enter a finer scanning pitch, then go to the Controller and click
[Scan]. Rescanning starts.
[Run 3D Editor] button
7. You can check and verify the scanning results in greater detail
by using 3D Editor. Click [Run 3D Editor] to start the program
and display the scanning results.
Viewing Scanning Results Using 3D Editor
Processing to merge multiple sets of scanning data is performed when you export these scanning results, but to speed up display, no process-
ing is performed when you display the results with Dr. PICZA3. This means that the view that Dr. PICZA3 shows may differ slightly from the
results after merging. If you want to check the appearance after merging, use 3D Editor to open the data you scanned.

4. Case Studies for Better Scanning
This example involves using the two scanning modes to scan an object that has a nearly cylindrical shape. You can use either mode for
scanning, but rotary scanning achieves the shortest scanning times. The scanning pitch is equivalent for both, but rotary scanning produces
smoother surfaces.

This is an example of an object finished using rescanning after rotary scanning and an object scanned using plane scanning. To determine
which of the two modes to use, you should decide how much you want to take advantage of the features of rotary scanning. Using plane
scanning eliminates the need to perform rescanning, but if smooth curves are important, then rotary scanning may be more effective.

Object Mounting Location for Rotary Scanning
In rotary scanning, the laser light is beamed toward the center of the table. This means that when the object is uneven, the penetration of the
laser light varies greatly according to the object's mounting location. This case takes this point into account and deliberately shifts the
mounted position away from the center. Note that plane scanning may be better suited to an object like this one. At this mounted position,
the back portion is not scanned correctly.
