If you have a laser business it’s often hard to find the time to create new designs when you are already busy with making existing products. One way to save time is to use existing “stock” images, to help fast-forward the design process.

There are many stock image services online where you can find existing vector designs, created by professional designers or independent artists. And each of these websites has a huge range of images, suitable for just about every occasion.

Just do a search for “royalty free vector images”, and you’ll find examples of services like Shutterstock, iStockPhotos, Adobe, Dreamstime, Vectorstock, etc.

Note: Although these images are ‘royalty free’ (you don’t have to keep paying every time you use them in your own products), the designs do usually cost something to actually buy in the first place.

There are also different types of license that you purchase. It is often free or fairly cheap (e.g. $1USD, or £1GBP per image) to download an image if you are just buying it for your own personal use. However if you want to sell products with these images on them, you usually need to buy an ‘extended’ license, which lets you make multiple copies of the designs and sell objects which include them.

Luckily, there are also a few rare sites and collections which include free royalty free images (!) for commercial use. In other words, this is where either the image is out of copyright, or the artist has given permission for other people to make multiple copies of their designs and sell objects that include it.

Examples of some of these sites include CraftsmanSpace, Vector4Free, FreeVectors,  BUT be careful again that the license allows commercial use (i.e. it lets you copy the image and use it on products that you sell).

Once you’ve found a suitable vector image on the website, here are the general steps you will need to follow:

Step 1: Download the image and save it in a folder or system where you’ll be able to easily find it again (e.g. create a folder called “vector downloads for commercial use”).

Step 2: Open a new document in your drawing/design software (e.g. CorelDraw).

Step 3: Import the saved vector into the new document.

Step 4: Then depending on your laser system: if you want to cut the image, make sure it has got hairline (or very thin) outline, and if you want to etch the image, make sure it hasn’t got the thin outline.

So that’s it. Instead of spending hours drawing and tweaking your own designs (when you could be doing some lasercutting), just search for a vector that you like, make sure that you’ve got the rights to reproduce it commercially, and download it into your drawing software.

Step by Step: How to Create Marquetry With A Laser Cutter

Marquetry is the art of applying thin veneers of wood to another (usually also wood) surface, to create a design. 

The method below is a fairly quick and ‘cheaty’ way to make marquetry-effect designs with a laser cutter.

Marquetry is the art of applying thin veneers of wood to another surface (usually also wood), to create a design.

The method below is a fairly quick and ‘cheaty’ way to make marquetry-effect designs with a laser cutter. I may write a post later on a different method, but in the meantime:

First you need at least two different types of wood, in different shades. One should be a very thin veneer-thickness wood (e.g. approx 1mm or 1/32in thick). The other should be at least twice as thick as the veneer wood (e.g. approx 2mm or 1/16in thick).

For example, your thicker piece could be a light birch wood, and the darker wood could be a special veneer wood.

The wood I used in this case comes from www.wood-supplies.com.  I’m not 100% certain which wood I used, but I think it was a sheet of 1/8in thick mahogany and a strip of 1/32in thick boxwood:

1/8in mahogany wood sheet and 1/32in boxwood strip

You will need:

 

Step 1: Create a design with whatever software you happen to use for your laser system (e.g. I use CorelDraw). I am making a simple flower design here, so I’m going to draw a basic flower with a circle ‘insert’ for the middle:

Note: As well as the design above, I also needed to design an ‘insert’ shape to put in the round hole above. So I duplicated the black circle and gave it an outline (see step 2 for illustration).

 

Step 2: Cut the insert shape from the veneer- thickness wood. (If it’s a very small piece, make sure you include a ‘sprue’ in the design, so it doesn’t drop through the cutting bed. For more info on creating sprues, please check out this article.)

Step 3: measure the thickness of the piece you just cut.

Laser-cut circle of boxwood is 0.79mm thick

Step 4: (Optional) If you’re starting from scratch then etch a test piece first. Measure how deep the etching is, then adjust the power/speed settings as necessary. You need to etch just a little bit deeper than the depth of the thin (veneer wood) piece. This is to take into account the layer of glue that will be used. So if your measurement of the veneer wood piece was 1mm thick, then you need to etch the design into the thicker wood so that the etched design is approx 1.2mm deep.

If there is too much charring or the etching doesn’t go deep enough even on 100% power, you may need to etch the same design again on top of the first etching, but perhaps on a slightly lower power setting. (e.g. if your veneer is 1mm thick but the etching is only 0.7mm deep, then you can etch the same design again but using less power the second time, or the second etching will be too deep.) Tip: DO NOT MOVE the piece of wood when you are measuring it, because if you need to etch again to go deeper then you want to make sure the second etch goes in exactly the same place as the first etch.

Tip: To measure the depth of the laser-etched circle, you can use the little gauge that sticks out of the end of the micrometer.

 

Step 5: Etch the design (the small circle, in this example) into the thicker wood. As mentioned above, you need to etch very slightly deeper than the thickness of the thinner (veneer wood) piece, to take account of the glue later. So if your measurement of the veneer wood piece was 1mm thick, then you need to etch the design into the thicker wood so that the etched design is approx. 1.2mm deep. Tip: If you’re etching twice, DO NOT MOVE the piece of wood after the first etch, because the etched design will be out of position when the finished design is cut.

Step 6: Cut the outer shape (the flower shape, in this example) from the thicker wood. Again, my laser and wood will be different to yours so I haven’t given the power/speed settings here, but if you are cutting the thicker wood for the first time then try a test piece first.

Etch the circle to the correct depth first, then cut out the shape.

Step 7: Apply a very thin layer of glue inside the etched design.

Step 8: Insert the thin veneer piece into the etched hole, and leave the glue to dry (time will depend on the glue manufacturer’s guidelines).

Step 9: Sand the surface of the marquetry piece so that the different woods are exactly level with each other and show no scorch marks from the laser.

Using “Sprues” in Laser Cutting Projects

How to fix common laser cutting problems: Add sprues to your designs…

Laser-cut paper shapes with "sprues" still connecting them to the paper.

What is a “sprue”, and why should I use them with my lasercutting designs?

Sprues are most commonly seen in injection-moulded plastic toys. For a fuller description check out the Wikipedia definition, but briefly:

In the image below they are the little links that connect the plastic toy components. They are created as part of the moulding process, but the useful secondary function of sprues is that they hold the components securely in position within a plastic frame, until you twist or cut the components out. So in the image below, you can see that the actual toy pieces are held safely in place until the user needs them, rather than the pieces just rattling around in a box or falling on the floor and getting lost.

In laser cutting projects, you often need to cut small pieces out of a light material such as paper, card, plastic or wood. But if they are smaller than the holes in the cutting bed of the laser machine, the pieces often fall through the holes and are lost as soon as they have been cut. Similarly if the machine blows or sucks air as part of the cutting process then very small pieces can just fly away.

Oh no! 75% of my laser-cut wooden circles have dropped through the cutting bed!
Oh no! 75% of my circles have dropped through the cutting bed!

So we need a way to cut the pieces, but to stop them falling down or blowing away. One solution is to include sprues in the cutting designs. (Generally speaking, they will be useful if the piece to be cut is less than 1cm squared, or if anything is being cut from a piece of paper.)

Sprues can be created very quickly and easily in most vector-based drawing software (e.g. Photoshop or CorelDraw). I happen to use CorelDraw, but the principles are the same for most other apps/programs:

Step 1: Make sure that you can edit curves and manipulate/add nodes on the cutting path of the design. (In CorelDraw it is the “Shape Tool” that allows you to do this.)

Note: If you can’t see any nodes to edit, you may need to convert the shape to curves first (e.g. by right-clicking the mouse and selecting “Convert to Curves”):

Step 2: Zoom in really close to the object (e.g. so that a 3mm line fills the whole screen), then add two new nodes as close to an existing node as you can manage:

Screenshot of CorelDraw adding nodes to curve

Step 3: Select the middle node of the three nodes that are very close together, and then break the path of the curve. (e.g. by right-clicking and choosing “Break Apart”):

Screenshot of CorelDraw adding nodes to curve
Screenshot from CorelDraw: breaking a curve

 

 

Step 4: That middle node should have broken in two, so take one of the two resulting nodes and drag it about half a millimetre outside the curve. Then do the same for the other new node. This creates a small break in the cutting line, so that when you the cut piece it should now remain fixed in place until you are ready to push or tear it from the material you were cutting.

Step 5: Push or pull the object out of the sheet of material that it is fixed in.

(You may need a knife or scissors to help cut it free, and then a file or a knife to cut away any extra material that is not required.)

New Business: New Blog!

New laser-cutting business blog

After years of running Key Crafts (which covered several crafts including polymer clay, papercutting, jewellery, cardmaking, and laser art), I have now spawned a new company, which will concentrate specifically on the laser side of the business.

“LaserSister” is the new branch of the business, and will cover the laser cutting service for other artists, plus my own laser-cut jewellery, gifts, cards and toys.

I’m aiming to create a blog which will share:

  • information about laser cutting resources that I create, and/or find elsewhere
  • designs for cutting
  • links to other laser-related sites
  • observations and lessons learned from running a laser-cutting business
  • information about the services and products I provide

…but if you’d like to request or recommend any laser-cutting-related posts or content, please give me a shout and I’ll see if they can be added to the blog.

In the meantime the first item to come out of the new business is this kitten brooch, with its little dangly bead instead of a ball of string for the kitten to play with. It should soon feature on my new Etsy and Folksy shops (now all I have to do is create the shops…)
