Roland Introduces the LPX-600 3D Laser Scanner for Easy, Professional 3D Scanning at the Touch of a ButtonHamamatsu, Japan, November 30, 2005 – Roland DG Corporation today announced the new LPX-600, a complete laser scanning package including software that easily scans a variety of objects to generate accurate 3D digital data. The LPX-600 is the industry's most user-friendly professional 3D laser scanner, with the entire scanning process controlled by a single button. Conventional 3D scanners, by comparison, require the advanced skills of experienced professionals to operate. "The LPX-600 3D Laser Scanner is an exciting innovation for the 3D CAD/CG industry, bringing unmatched ease-of-use to an otherwise complex process," said Toshi Yahiro, Roland DG 3D Product Manager. "Now, for the first time, anyone can easily generate high-quality 3D digital data. In fact, the LPX-600 is as easy to use as a flatbed scanner. Yet it delivers professional results, automatically filling holes and deleting polygons where needed for smooth surfaces and easy editing."
Scan your object in three easy steps
With the LPX-600, scanning is completed in just three easy steps:
1.Position your object on the LPX-600 work table
2.Press the "Preview" button to confirm scanning time
3.Press the "Scan" button to begin scanning

3D Scanning with the Modela MX-20
3D Scanning with the Modela MX-20 In order to investigate as many 3D scanning methods as possible we decided to work on some of them as a group and then take one each to write up.
The Roland MDX-20 can be used for 'Tactile Scanning' of objects as well as milling. The process essentially involves delicately moving a long needle tip around over the model and prodding it to work out where the surface is at any point.
1. What Object to Scan?
We decided to try and find an object that we would be able to scan with as many methods as possible. This proved quite awkward as the different methods we planned on trying all work best with different scales of object. We settled on a pencil sharpener as it's quite an interesting shape, has some surface detail, has a flat bottom surface so that it's easy to stick down and has a chance of producing a scan with the Modela, 123D Catch and FabScan.2. Modela Setup
The machine requires a small amount of setup, basically the milling head needs to be replaced with the scanning head. The heads are only held in place by 2 'alan' screws so this is a fairly quick process.
Once the machine was setup we stuck our object down on a flat part of the Modela bed with double sided tape.
3. Software Setup
We had been using Fab Modules in Ubuntu for all the milling work with the Modela, unfortunately scanning with the Modela is currently only supported by the official Roland software called 'Dr PICZA' which only runs under Windows.Dr PICZA proved to be quite intuitive to use and after 10 minutes fiddling around with it, investigating, we were happy we knew how it worked.
3.1. Setting Scan Area
First thing to do is tell the Modela the area of the bed that requires scanning. Getting this as close as possible to the boundaries of the object will reduce the scanning time. Our initial estimate was by measuring from the lower left corner of the Modela bed. We put these measured numbers for x-min, x-max, y-min and y-max into the scan area dialog and then used the 'Begin Area Test' button to check them.
The software gives you a visual representation of the scan area with drag handles that can be used to adjust it. This gives a quick initial visual check of the area to be scanned.For the 'area test' the Modela moves around the boundary of scan area lifting the needle up as far as it will go and dropping it at each of the corners and mid points of the of the boundary in turn (these are the same points as shown by the drag handles on the image).
This test allows us to refine the scan area from our initial measurements, moving the boundary in closer to the object so that the modela has less area to sample. We iterated this scan / refine boundary a few times until we were happy that we weren't scanning a large area of the flat bed but our scan was still well clear of the edges of the object.
3.2. Z Upper Limit
One thing that was obvious to us from watching the 'Test Area' process was that it takes an appreciable amount of time (around 15 seconds per cycle) for the Modela to lift the test needle as high as it will go and then rop it back down again.
Obviously with no other information about the object being scanned the software has no choice but to do this. We realised that if we use the 'Z Upper Limit' function we could tell the Modela the upper extent of the object on the Z axis and it would know that it only needed to lift that far to clear the object as it moved around.Setting the x, y position of the highest part of the object and clicking 'Apply' causes the Modela to move the needle to this position and drop it down to test the actual height at this point. By watching closely as it did this we could refine the x, y co-ordinates to get an accurate measure of the maximum height. hopefullyy this would save some time in the scan process as the Modela wouldn't need to lift the needle the whole way up as it moved it around. Watching the Modela actually perform a scan later showed us that even without this info it seems to be slightly more intelligent than this.
4. Scanning
Once the scan area had been set up we set the x, y scan pitch and clicked scan. The software defaulted to 1.00mm for the x, y pitch when we launched it, so even though this didn't sound like it would give us a very accurate scan we decided to start with this to watch how the machine worked and then refine it later.The image below shows the scan in progress.
You can see from the image above that this scan is about a 3rd of the way through and still has about 12 minutes remaining until it is complete, so a total scan time of about 15 minutes. Our scan area was 22mm by 30mm, at 1.0mm pitch this is approximately 713 points including the boundaries. At 15 seconds per point samlpe this is around 180 minutes. So it looks like setting the z upper limit has had a significant effect (Or maybe the machine is cleverer than we think!).
And finally the mesh generated with our initial 1.0mm pitch scan.
You can see from this that even though the pitch was only 1.
0mm, the scanned object is still clearly identifiable. However it's missing all of the finer detail such as the ridges on the finger indentations and the texture on the upper surface.
So we decided to refine the scan pitch and see how the detail changed. Below is the final mesh at 0.5mm pitch.
And this one below at 0.25mm scan pitch, this took around 2 hours to complete the scan.
At 0.25mm detail in the object is becoming clearly visible. You can see the following features:
- Dimpled texture on the upper surface of the sharpener body.
- Cross head screw holding blade in place.
- Difference in height of blade and body.
- Cutting edge of blade.
- Knurls on finger grips at side of body.
Given time we may attempt this again as we would like to see what this machine is capable of.STL Files for the 3 scans that worked are here, here and here.
5. How does it Scan?
The simplistic way to scan would be to step across the scan area in pitch step increments completely raising the scanning tip each time and then dropping it back down again. Based on our quick time to scan estimate earlier on vs. the actual time it took to do a scan and on observations of the machine scanning the process appears to be much more intelligent than that.The first thing to note is that t needle doesn't operated a simple switch when it drops down and touches the object. It is actually a piezoelectric sensor. This means that it will resond to deflections in the x and y directions as well as the z. With this the machine appears to sweep the tip across the object at a constant low height until it touches an edge. When it touches it lifts up until it clears and then continues it's sweep.
with this information it can work out a better approximation of the boundary of the object than that provided by our simple scan area estimates and z upper limit. With this better boundary information it returns and performs a high resolution scan of the object only just lifting the scanning tip just enough to clear the object and saving a lot of time moving the head on the z axis. 6. Printing our Scans
Having scanned our pencil sharpener we decided to try and print a copy and see how close to the original it looked. Our original print was at 1:1 scale, but at this resolution the printer (our in lab Ultimaker) wasn't capable of reproducing some of the detail that was visible in the mesh, so we decided to scale the print up to 2.5:1 to see how much detail had actually been captured. The original and both models are shown together in the image below.
