| {color:black}{*}Introduction:*{color} | {color:black}The 3D scanner has   only limited functionality in that it performs a very specific purpose.{color}{color:black} {color} {color:black}However, it can be an invaluable tool   especially for those whose design practice moves readily between analogue and   digital methods.{color}{color:black} {color} {color:black}The 3D printer acts   as an interface between these two by transferring real-world objects (form)   into 3D digital solid models.{color} |
| {color:black}{*}Capabilities:*{color} | As noted, the 3D scans real world   forms and converts the scanned data to a digital model.  However, there are certain constraints to   the scanners capacities which are default.  These have primary impact on the type and size of the model which can   be scanned, and therefore, to an extent, on the successfulness of the scan   itself in digital format. \\  {color:black}{*}1.*{color}{color:black}*    *{color} {color:black}{*}Size{*}{color}{color:black} {color} {color:black}The 3D scanner has an internal scanning   chamber measuring 250mm in diameter and 400mm high.{color}{color:black} {color} {color:black}The object that you wish to have scanned   must therefore be able to fit inside these parameters.{color}\\  {color:black}{*}2.*{color}{color:black}*    *{color} {color:black}{*}Materials{*}{color}{color:black}* *{color} {color:black}The 3D scanner scans using laser.{color}{color:black} {color} {color:black}As such the material of the object to be   scanned must be opaque so as to be readable by the laser.{color}{color:black} {color} {color:black}Therefore, any glossy, mirrored or translucent   materials will not scan properly.{color}{color:black} {color} {color:black}If   you are working in this material or have a section of your model which is   made using them, you have two options.{color}{color:black} {color} {color:black}Either you can powder coat or paint that surface so as to render it   opaque.{color}{color:black} {color} {color:black}Or you can submit the material   to scan as it is and simply recreate the void/partial scan areas in your   digital model later.{color} |
| {color:black}{*}Use:*{color} | {color:black}In order to use the   digital scanner you will need to follow the guidelines here.{color}\\  {color:black}{*}1.*{color}{color:black}*    *{color} {color:black}{*}Appointment{*}{color}{color:black}* *{color} {color:black}Scanning is by   appointment only.{color}{color:black} {color} {color:black}To organise a time contact   the Media Centre Helpdesk staff in person or send an email to Media Centre at{color} {email address}{color:black}.{color}\\  {color:black}{*}2.*{color}{color:black}*    *{color} {color:black}{*}Conduct Scan{*}{color}{color:black} {color} {color:black}Scanning is performed by the   student with assistance from Media Centre staff.{color}{color:black} {color} {color:black}You will need to bring along your model   making sure it meets the dimension specifications outlined above.{color}{color:black} {color} {color:black}The software used to scan is Dr. Piczar   which is similar in layout and usability to any standard 2D scan interface.{color}\\  {color:black}{*}3.*{color}{color:black}*    *{color} {color:black}{*}Scan Time{*}{color}{color:black}* *{color} {color:black}The length of time   to scan your real world object is not easily predicted.{color}{color:black} {color} {color:black}It more or less depends on the size and   complexity of the object and also the resolution required of the digital   model.{color}{color:black} {color} {color:black}Dr. Piczar offers preview   functions from which the student can determine resolution desired.{color}{color:black} {color} {color:black}Having said that, the average scan time   would roughly be around 20 minutes.{color}{color:black} {color} {color:black}There can be delays though, and especially in the busy season (leading   up to crit).{color}\\  {color:black}{*}4.*{color}{color:black}*    *{color} {color:black}{*}Output{*}{color}{color:black} {color} {color:black}There are various filetypes and   outputs available.{color}{color:black} {color} {color:black}By default the 3D   scanner outputs a surface but a solid can easily be created from this, either   in Dr. Piczar or later on in the likelikes of{color} {color:black}{+}Max{+}+[Max|MediaCentre:3DS Max]+{color}{color:black}.{color}{color:black} {color} {color:black}The 3D scanner will give you a model in STL   format or as a POINT CLOUD or in TXT which is mainly of use in{color} [Rhino|MediaCentre:Rhino] {color:black}{+}Rhino{+}{color}{color:black}.   The.   The most common of all filetype outputs is DXF which almost all 3D programs   can read.{color}{color:black} {color} {color:black}Media Centre recommends you   use this last filetype when you are using the 3D scanner.{color} |
| {color:black}{*}Costs:*{color} | {color:black}The 3D scanner is free   to use.{color} |
| {color:black}{*}Strengths/weaknesses:*{color} | {color:black}Over and above those   strengths and weaknesses listed already, the 3D scanner at present is:{color}\\  {color:black}\+\+ Much faster when   compared to digital modelling.{color}{color:black} {color} {color:black}The   scanner is fast and offers great experimentation opportunities.{color} {color:black}  {color}\\  {color:black}\+\+ Excellent in that   it provides a good and easy interface between analogue methods and digital   modelling.{color}\\  {color:black}+ Good at providing a   nice, easy reference model from which to continue building in your 3D   modelling program of choice.{color} \\  {color:black}\- Poor in accuracy   when scanning, - be prepared to lose some detail.{color}\\  {color:black}\- Poor in material   selection as it cannot scan shiny materials.{color}\\  {color:black}\- Poor in scanning   internal space.{color}{color:black} {color} {color:black}For example, if you   have vase or vase type{color}{color:black} {color} {color:black}model, the 3D   scanner will only scan the external surfaces.{color}{color:black} {color} {color:black}As yet, we have nothing which can scan both the external AND internal   surfaces.{color} {color:black} {color} |
