Overview

3D Systems has made available a set of "General" 3D Lightyear 
Build and Recoat style files which have wider parameter editing 
ranges than the default Standard and Advanced styles provided 
with the 3D Lightyear release CD-ROM.  These files are intended 
for experienced users who want to go beyond the limits of the 
default Standard and Advanced styles to accommodate new 
applications or alternative stereolithography resins.  

These style files are not resin specific, but are grouped in 
self-extracting archives according to machine type.  The 
archive file names for the Advanced styles are:

     SLA250_GenStyleAdv.exe
     SLA500_GenStyleAdv.exe
     SLA3500_GenStyleAdv.exe (also used for SLA350)
     SLA5000_GenStyleAdv.exe
     SLA7000_GenStyleAdv.exe

and for the Standard styles:

     SLA250_GenStyleStd.exe
     SLA500_GenStyleStd.exe
     SLA3500_GenStyleStd.exe (also used for SLA 350)
     SLA5000_GenStyleStd.exe
     SLA7000_GenStyleStd.exe

The individual style files within the archive follow a modified 
naming convention as follows:

     P7000FZG0050in.sty
     P7000FZG0050in.rcs
     S7000FZG0050in.sty
     
These are the General FAST style files for an SLA7000 system. 
Note in this naming convention, the "7000" refers to the machine 
type, not the resin type. The other conventions used are as 
follows:

  H=Hex                   G=General
  F=Fast       Z=Zephyr   I-Inclined
  X=eXact      R=Regular  V=trapped Volume
  B=Box        (Doctor)   D=Delicate
  T=Tooling    N=None     L=Large flat
            \     |     /
             \    |    /
              \   |   /       rcs=Recoat style
               \  |  /        sty=Build style
                \ | /        /
            P7000FZG0050in.sty
  P=Part   / ----   ----  \ 
  S=Support    |       \    in=inch
               |        \   mm=millimeters
               |         \
          Machine Type     Layer Thickness

Once the archive has been downloaded and extracted, you use the 
styles just like the Recommended Baseline styles included on the 
3D Lightyear release CD-ROM. That is, because the Setup New 
Machine wizard does not know of their existence, you must 
manually apply the "General" styles to your platform using the 
"Browse" function to locate the desired files.  Once they are 
applied to the platform you can use the parameter editing tools 
in 3D Lightyear to adjust the parameters for your requirements.

You can create a Support recoat style by starting with a Part 
recoat style and set the dip distance > 0, and the number of 
sweeps = 0.

Installation

1. Download the desired archive file (or if you received it via 
   email, Save the archive file) to a temporary folder on your 
   hard disk.

2. From Windows Explorer, double-click on the archive file name.
   This will bring up the WinZip Self-Extractor dialog.  Note 
   the default destination is:

   c:\Program Files\3DSystems\3D Lightyear\styles\General\Advanced

   for the Advanced styles, and:

   c:\Program Files\3DSystems\3D Lightyear\styles\General\Standard

   for the Standard styles.

3. If this is not the folder you want to extract the files to, 
   Use the "Browse" function to locate the desired destination 
   folder.

4. When the desired destination folder appears in the "Unzip 
   to folder:" window, Click the Unzip button.
   
   If the destination folder does not exist, the self-extractor 
   program creates it, as well as sub-folders for the inch 
   and metric forms of the styles.  The files are then 
   extracted and copied to the destination folder.

5. Click the "Close" button to end the self-extractor program.
   The new styles are now ready to use.
