11 Part 2 Basics of the LPX-250 1. Scanning System Rotating table Laser emitter Sensor 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. The[...]

Part 2 Basics of the LPX-250 12 Brightly colored objects (white, yellow, red, etc.) Dark-colored objects (black, blue, green, etc.) Objects of a nonglossy material such as plaster, wood, or modeling clay Glossy and highly reflective objects (metals, mirrors, etc.) * Applying white surfacer (primer) may produce better results. * A void highly reflec[...]

13 2. Suitable and Unsuitable Objects for Scanning 3. Plane Scanning Plane scanning system Multi-plane composition (four scanning surfaces) 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 [...]

Part 2 Basics of the LPX-250 14 Rescanning 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 effect[...]

15 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 af fected 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 (T wo to Six Scanning Su[...]

Part 2 Basics of the LPX-250 16 Rotary Scanning 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 de[...]

17 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 Does the objects not pass light? Consider applying a white surfacer (primer). color Is the object a bright color such[...]

Part 4 Features for Better Scanning 22 The Important Point Is to Use the Minimum Required Scanning Area The smaller the scanning area is, the sooner scanning finishes. Y ou can achieve efficient scanning by making the setting for the minimum area that is required. If you don't actively set the scanning area, the entire scannable area is scanne[...]

25 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 i[...]

Part 4 Features for Better Scanning 26 4. Hold down the SP ACE 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). 5. Drag[...]

27 Scanning a Specific Area in Greater Detail Y ou 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 [...]

Case Studies for Better Scanning Scanning Results for Objects That Are Difficult to Scan These are some examples of scans of difficult materials. (The plate[...]

29 This example involves using the two scanning modes to scan an object that has a nearly cylindrical shape. Y ou 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. Rotary scanning Pitch of 1.4 mm x 1.6 degrees Scannin[...]

Part 4 Features for Better Scanning 30 The Scanning-start Direction for Plane Scanning This is an example where the scanning-start direction is changed with plane scanning. It is a good idea to give thought to the direction in which cavities and voids can be most easily captured (that is, the direction in which the laser beam passes), and also to k[...]

31 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 posit[...]
