Allowances: as the laser uses the energy of a focused light to do its cutting/etching
by vaporising the surrounding material a small allowance should be compensated for in your drawings. Certain materials behave differently but as a guide the following should
help. Note that lasering cannot accurately cut to a
certain depth, but will be as close as material properties and time
A 10mm square hole should be drawn at 9.8mm.
If you want to slice a piece of wood down to 20mm x 10mm then your drawing should be 20.2mm x 10.2mm.
Please indicate on your emails or drawings whether you have made the allowances.
The maximum depth achievable is 9mm in
Vector cutting: cuttings lines (all the way through) should be shown as red where possible. These are shown as 0.01mm in cad or
hairline in Corel software or the
minimum your software will allow. This is known as a vector cut. Your
drawing should explain what depth you want in mm.
Generally I use red to cut but if there are multiple cuts or scribing I user
orange as a cut through as this is the last
colour in the laser list. The laser cuts in in the following colour order (
black, red, green, yellow, blue, magenta, cyan, orange). I can however over
ride this. Eg I could use a red hairline to
release the windows from the body and green to
do matchstick boards and orange to cut the side
from the material. There is plenty of flexibility, just let me know
what you want.
Vector scribing: is simply a line that does not go all the way through your material. (i.e. scribed lines in basswood representing corrugated iron sheeting). Line colour can be almost any colour so long as the drawing states its purpose or is clearly explained in an email.
Rastering / engraving: Generally speaking this is a solid area that
is engraved away from its surrounding material and solid black is usually
used to represent this but takes a lot more time on the laser. The
Spirit Design logo above is a good example of a rastered logo. If you
want more than one depth of rastering / engraving it can be separated by the
use of shades of black (black to grey to white).
No Drawings Provided: In some cases you might not be able to draw what
you want and will leave it up to me to produce laserable drawings.
Prototype drawings or sketches can be provided in most formats, eg Tiff,
JPEG, AI, DXF, DWG, etc. or just plan paper plans. Good clean high contrast
copies are desirable. When in doubt please contact me.
CD's and DVD's of large files are better. Drawing and research costs
are charged at $44 for the first hour and $11 part there of (15 minute
Special note for Corel users:
Please check that you don't superimpose multiple cut lines on top of each
other as the laser will cut the same line twice. This is a common 'Gotcha'
that arises from duplicating items in drawings.
