When I was a newbie in laser engraving, there is much I was not doing the right way. And I believe there are engravers out there who are like the way I was. One of the things I didn’t know was how to save time laser-cutting multiple objects. Before I learned the trick, I am going to share with you; I used to spend a lot of time. And in engraving time matters a lot.
How was I doing it?
Let me demonstrate it with an example. For instance, when I was cutting several rectangular shapes from wood sheets to make key chains, I used to draw them separately in CorelDraw as in Image 1 below. After drawing them, then I would send the job to the laser machine to cut the shapes.
Cutting shapes separately as you see in the image above wastes a lot of time. Surely, if you do it that way, you spend more time on any given job. Secondly, you increase the cost of doing the job because you use more electricity. Thirdly, because you use more time and more electricity, you are forced to charge more to your customers to cover the cost of doing the job.
How Do You Save Time Laser-cutting Multiple Objects?
To save time when you’re laser-cutting multiple objects, you put the objects together at the time of preparing your job as in Image 2 below.
But when you put them one against each other, the lines overlap. And when they overlap, they look like you have one single line. But in the real sense, the computer sees two lines where they overlap. If you leave it like that, your cutting time will not reduce because your lines will get cut twice where they overlap. The cutting time will remain the same as in Image 1. So what do you do?
The solution is to remove the overlapping lines and remain with one cutting line. Let me share with you how I do it in CorelDraw. And I believe the same trick is possible even in other graphics software programs.
Merge the small rectangular shapes into one big rectangle by using the welding tool as in Image 3. above Then after welding each square onto the other to make one big shape, draw lines with a Freehand tool both vertically and horizontally following the shape nodes as you see in Image 4 below. That’s it. You’re now done with the preparation of your job, ready to send to your laser. And that’s how you save time laser-cutting multiple objects.
Now, the laser will cut the material following the inner vertical and horizontal lines of the big rectangle instead of cutting each shape separately. If you do it this way, you save time by about 50%, which is great.
Learning to save time laser-cutting multiple objects has several advantages. Apart from reducing your job running time short, it helps you to reduce the job costs, increase your efficiency and productivity. If you do it, you even make more money.
