Laser Engraving Multiple Objects Tricks Are Revealed

Apr 10, 2019 | Knowledge Base

Laser Engraving Multiple ObjectsWhen I was still a novice in the engraving industry, I received an order of engraving 200 smartphones. I spent long engraving because I was putting one phone at a time in the laser machine. I wasted a lot of time unnecessarily and made the client get tired of waiting. Why? I had not yet learnt the tricks of laser engraving multiple objects.

I know there are engravers out there with the same challenges I had. If you’re one of them, this post will save you a lot of time. There is no reason why you put one item at a time and engrave one by one. It’s better and time saving to put several items and engrave them at once and in the shortest time.

Laser Engraving Multiple Objects Has Several Advantages

Before getting into the tricks I use, let me first share with you the advantage of laser engraving multiple objects. They include the following:

#1 – Saving time

The first benefit you get is saving time. When you engrave one item at a time you waste a lot of time. The time you spend to put the item into the laser machine and to remove it after engraving it is much. And in engraving, time is money.

#2 – Reduce on the engraving cost

The more the time you spend running the machines you use in engraving (i.e. laser machine, extractor fan and air compressor) the more money you will spend on power consumption. This reduces your profitability. But by laser engraving multiple objects, you cut down on these unnecessary costs.

#3 – Increase your productivity

Engraving one object at a time reduces your productivity. For instance, when you spend more time on one single job in a day, it makes you postpone working on other customers’ jobs. But laser engraving multiple objects will lead you to improved productivity.

#4 – Serve your customers satisfactorily

When customers come with their items to be engraved and you spend less time, they feel good. This leads to customer satisfaction, which is very beneficial to your business.

#5 – Saving energy

You lose a lot of energy and get tired for nothing when you engrave one item at a time because of the burden of putting and removing them from the machine. But when you layout several items and engrave them once, you save your energy.

To effectively laser engrave multiple objects, use the following tricks.

First Trick: Create Target Shapes

Target Shapes

Let us say that you have 100 smartphones you want to engrave with serialized identification numbers at the back of each of them. And the client wants you to put the numbers in a specific place inside the phones.

What you do is to measure accurately the size of the phone to create a target shape. Let us assume that the phone size is 7.2 cm by 13.7 cm. So your target shape will be of that size and it has to be drawn in the vector or cutting mode. Draw it in your designing program i.e. CorelDraw as in the image above.

After drawing the target shape, then measure the exact location of the area where you’re going to engrave the identification number in the target shape. Place the identification number or design in the target shape.

Second Trick: Layout your Artwork in Layers

Using Layers

When you’re drawing the target shape, place it on one layer and the identification number on the second layer. And because you’re going to engrave 100 phones, you will have to create more layers to cover all the 100 phones each with a different serial identification number. Hope you have got it right. This will make it easier for you to hide some layers as you print with your laser what is on a single layer.

After placing the target shape on one layer and the design on another layer, select the two items and duplicate them to make as many copies as you can fit in the space of your engraving area. In our example, we have duplicated both the ID number and target shape nine times to come up with  a total of 10 phone target locations that are enough with an engraving area of 18 inches by 12 inches.

Then copy all what is on the layer with the design or identification numbers and paste it on other layers. The number of layers will depend on the number of objects you are going to engrave. For our case, we have created 10 layers of 10 phones each and each phone is given its own serialized ID. Because each phone has its unique identification number, you’ve to change the numbers first on each layer before proceeding on.

Third Trick: Use Color Mapping

Color Mapping Property

Sorry if you’re using other brands other than Epilog because it’s only Epilog laser engraving systems with the color mapping feature. Next time you plan buying a laser system, consider buying from Epilog to enjoy this wonderful function.

The color mapping feature helps to quickly set up your designs for faster run time and more precise engraving. This feature allows you to assign different speed, power and frequency settings to different colors in your design. The color mapping dictates where and when to engrave or cut.

Color Mapping Feature

For instance, in our phone engraving job, we are going to engrave 10 phones on each layer. If you don’t use color mapping, the machine head is going to move from the extreme left to the extreme right of your engraving area. By so doing, it will be covering even the spaces without anything to engrave. This consumes more time. And remember that time is money in engraving.

But with color mapping, the head will engrave following a particular color and in the order you have set them up in the color mapping property. This means that the laser will skip empty spaces and only engrave where you have the design. The color mapping function is therefore a great way of saving time when laser engraving multiple objects.

Fourth Trick: Create a Fixture

You have to use a fixture when laser engraving multiple objects. The concept behind creating an engraving fixture is to give you an accurate engraving position guide so that you can place the items you’re going to engrave in the exact  spot on the engraving table. You can laser cut this fixture from any materials such as cardboard, plywood, acrylic sheets and many others.

Fixture Material

Get the material for making your engraving fixture, cut to the size of your  laser bed, and place it in your laser engraving machine  underneath your rulers so that it does not move in the process of running your jobs. Make sure that only the layer with your target shapes is set to print. It’s good to turn off the other layers from viewing so that you don’t see them because we don’t need them at this stage (refer to image below).

Unwanted Layers Turned Off

Having set the job for printing, send it to the laser to cut the target shapes into the material to create a grid that matches the one in your designing program. Remove the cut pieces from the fixture to create open spaces for positioning the objects you’re going to engrave.

Cut Pieces Removed

Having removed the cut pieces, now place your objects (or phones in this tutorial) and begin engraving them. Do not forget to refocus the lens on top of the objects you’re going to engrave. Secondly, turn off the layers with the artwork that you’re not engraving. That’s all you’ve to do when laser engraving multiple objects.

Conclusion

If you want to save time and to increase your productivity, equipping yourself with tricks of laser engraving multiple objects in the shortest time will help you to achieve it.
