Here is a great way to use laser cutting to help your brand stand out from the crowd. We already know that laser cut letters have serious impact when compared to printed alternatives… there’s something that really grabs you when a typeface stands proud in 3D.
For Agencies and Brands, the need to go one step further in order to draw in the target audience can lead to some interesting design explorations.
The use of food, with all of its associations and temptations, opens up a number of unusual opportunities to enhance laser cut objects.
We’re wired to respond positively to sweet things. There’s something about desserts, particularly sweet ones, and it’s hard to get any sweeter than honey. Putting the sensorial experience of eating honey aside, actual honey is also a visual marvel with its mesmerising molten viscous motion and deep golden glow.
Here is a great example of this combination of food and laser cutting working really well together. Giving laser cut letters a unique eye-catching appeal, this experimental typeface takes inspiration from the classic wooden honey dipper. It is only once the honey is added that the letters become complete.
“We were attracted to the simplicity of structuring layers of wood, the mesmerizing viscosity and warm tonalities that honey has.”

When an artist has the knack of truly capturing a portrait, the result will often have a commanding presence that engages and challenges the viewer. Andrey Adno’s portrait series In Myself uses laser cutting to add depth and personality with a distinctive visual style that is quite mesmerising.
The portraits are presented across a variety of scales, from life-sized material explorations to an enormous exhibition installation that is illuminated from within.
Light, shadow and the intriguing qualities of translucent acrylic all play a role in supporting the layered laser cut contours to define the form. These physical works show a high level of detail and present a novel interpretation of the artistic portrait.
The changing impact of light and shadow through different material explorations encourages a range of emotional responses to the portrait series.
Fans of street artist 1010 are also in for a treat, thanks to an interesting digital exploration Adno is working on. With a mesmerising organic motion, the smooth forms swirl and blend to expose and then conceal across several layers of material.
What you see in the animation below is a part of a work-in-progress; a “test version” digitally produced using Maxon’s Cinema 4d program. Although this will not become an actual physical artwork, the connection to Adno’s earlier laser cut pieces continues through the use of layers and cutout contour lines.
Watch your brand take flight with this playful idea for a business card makeover. Canadian model aircraft supplier Norburn put a sample of their wares right into potential customers’ hands thanks to a snap-fit mini glider incorporated into their business card design.
The simple but fully functional flyer easily assembles from three components that pop out of the card. The fuselage and wings give plenty of space to lay out all the key company info, and although the assembled plane may not fit back into your wallet so well, chances are you’re not going to forget these guys any time soon.
Inspiration for your brand
The surface area provided by a business card may be small, but as this glider shows, that doesn’t mean you can’t have fun there with some laser cut designs. Taking an aspect of what your company does, and turning it into a simple 3D assembly, gives people an interactive way to engage with your brand and generate a memorable connection. Adding in the functional element of (in this example) a glider that can actually fly would make for a real conversation starter at events or in the retail environment.

A unique image appears on each rotation of this transparent acrylic cube
There was definitely some careful planning going on when artist Thomas Medicus put together this remarkable laser cut cube titled ‘Emergence Lab’. Upon rotation, a new hand-painted image is revealed from each orientation with a dynamic three-dimensional impact. It really is quite mesmerising… continue reading below for an HD clip of the cube being rotated through all axis.
The cube consists of 216 laser cut acrylic strips assembled into a grid structure. This enables an anamorphic painting to be positioned on each side that is only able to be seen in complete clarity from one specific viewpoint. In order to retain the integrity of the transparent cube, the images have to occupy the same physical space as their counterparts on the opposite side; adding to the complexity of the hand painted designs.
By using this method of construction for the cube, it makes the task of applying the images much more straightforward – but also results in unwanted reflections within the structure. To get around this, Thomas came up with a clever solution: fill the cube with a silicon oil that has the same refractive index as the acrylic structure. This gives the visual impression of a solid glass block, as the individual facets and surfaces of the acrylic strips blend away to become almost invisible.
Can you think of other ways to use silicon oil to enhance the impact of laser cut acrylic from the Ponoko Personal Factory? Let us know in the comments below.
The play of light and shade on crisp laser cut linework has an eye-catching impact that is both dynamic and alluring. With only a little more effort than it would take to prepare files for printing in a more traditional 2d format, it is possible to use the same visual structure to create laser cut layered artwork that can literally jump out from the page.
Why does it work so well?
The example pictured above demonstrates that this approach to 3-dimensional graphic design can be applied with great effect to simple text and logos. When given only a partially complete outline of each letter, the eye naturally resolves the missing details. Further support from environmental lighting can also enhance the stratification in the design. This allows the geometric forms of the custom font to be instantly recognisable even without prior knowledge of what the typeface looks like.
How to use this technique with your brand
Some of the best laser cut designs are also the simplest. This is particularly true when working with layered material and sections that are cut or removed; the less complicated your design can be, the fewer the potential errors when it all comes together. Remember to work with the strengths of laser cutting, making use of (to name a few): crisp linework, precision alignment and the elegance of accurate repetition.

Fitting all of your laser cut parts so that they squish into the least possible area on your laser cutting template can be tricky. Most of us will approach this by trial-and-error, manually shifting objects around until it ‘looks about right’. While this will save a bit of laser time, with complex designs the process can be laborious and you can’t really know whether the layout you have chosen is the best possible solution.
That’s where clever software such as Jack Qiao’s SVG Nest can really come in handy.
What is SVG Nest?
Rivalling powerful (and expensive) commercial options, the freely available SVG Nest uses all the computing muscle your browser can throw at it to come up with the optimal layout for your laser cutting. By grouping all of the elements within a defined area, the geometry-driven genetic algorithm is able to find the best fit by first setting the largest shapes, and then working in the smaller objects around them. It gets really interesting when there are many many design elements, and also when the objects to be sorted are all of a similar size.
Here’s an example using laser cut lettering:
Why is this useful for laser cutting?
As we’ve previously outlined in the Top Ten Ways To Reduce Laser Cutting Costs, how you position your designs on the Ponoko template can really make a difference to your laser cutting pricing. One of the reasons for this is that the laser head has less distance to travel between each part, and as you are paying for laser time, minimising travel is an immediate cost saving. Another consideration is the material cost itself – minimising material wastage will also save you money. As an added bonus, being thrifty with your resources can make you feel good too!
For more information about SVG Nest head to Jack’s GIT repository, where you can also see a demo of the software in action. Just be warned, it is seriously CPU intensive so those on mobile devices might want to wait until they’re sitting in front of a harder hitting machine before trying it out.
Give a bunch of people something round that can be thrown, caught, bounced or rolled… and within moments an impromptu game will have started. Even the non-sporty types are likely to join in, so strong is the allure of the ubiquitous ball.
This clever flat-packed ball from Instructables user Scientiffic is comprised of only two simple laser-cut components. Repeated and then snapped together with no need for glues or adhesives, it is a neat example of how you can make a robust and functional object from basic elements.
What does an object like this do for your brand?
Engaging customers with a physical object that can then become a light-hearted networking tool allows your brand to form a different kind of association at an event. Incorporating the tactile process of assembling the ball, then adding in the element of play either as an introverted solo activity or as a way to interact with others may indeed prove to be more engaging (and therefore more memorable) than the usual event swag.
A vehicle for your corporate identity
The example here from Instructables shows the components of a ball that have been laser cut from wood. Ways to adapt this design could include the addition of company branding as a laser etched detail, or even changing materials to use acrylic in colors that match your company’s colorway. Other options to generate interest and encourage interaction could involve the addition of simple electronics to illuminate the material from within, or add engagement triggers such as sound or motion sensitive functionality.

Beginner’s Guide to Digital Imaging Formats for Laser Cutting
One of the great things about laser cutting is that it makes high-quality outcomes both accessible and affordable. Some new users are happy to dive right in, but others need a little extra help in the early stages… and that’s what we are here for.
Before you get started it is a good idea to familiarise yourself with some of the basic knowledge and terminology associated with laser cutting. Understanding image formats used in the preparation of artwork for laser cutting is one of the common hurdles that newcomers face.
Let’s take a look at the difference between Vector and Pixel artwork, and what this means for laser cutting.
First up: Pixels
Bitmap images use a grid of ‘Picture Elements’ (pixels), each with a specific set of information. This is a fantastic choice when creating or editing images because there is a high level of control over tones, textures and colors. The sensor in a digital camera records information in this way, and image editing programs such as Photoshop use pixels to work their magic.
Common file types: TIFF (.tif), BMP (.bmp), GIF (.gif), JPEG (.jpg).
Pixels: the good
The upside of pixel-based images is that you have such great control that allows you to replicate all the color and detail of the physical world, and so long as you have the original data, edit to your heart’s content.
Pixels: the bad
Image size. Because data is being recorded for every single pixel, as images get larger, so too does the amount of information needed to define the image. Larger file sizes means more storage space required, and more computing power to process the extra information. Also, Pixel-based images do not scale well. While they can be reduced in size, doing so will result in permanent data loss. This means that image quality will suffer if you try to increase the pixel dimensions, because the computer has to guess how to fill the extra space now that the data is no longer available.
Vectors are best known for their use in typography, drawings and graphic art such as logos. The way that images are created using Vectors is quite different from Pixels. Vector graphics are defined by mathematical equations – they take points, connect them with lines in various shapes, then fill with a color or gradient range. To achieve more complex shapes, there would simply be more and more points and lines. Programs such as Illustrator and Inkscape work with Vectors to create images.
File types: Encapsulated Post Script (.eps), Adobe Illustrator (.ai), Scalable Vector Graphics (.svg).
Vectors: the good
The big thing about Vectors is that they are scalable. No matter how close you get, vector artwork will always be crisp and sharp – independent of the image resolution. The same information (and the same sized Vector image file) can be used to draw a circle whether it is 1mm across or big enough to feature on a billboard. File sizes remain small, regardless of the scale of the image.
Vectors: the bad
There is one notable disadvantage with Vectors; they are not well suited to creating photographic images. This is because the volume of information would become so large as to work against the strengths of using the Vector format.
How does laser cutting fit in?
For laser cutting, Vector paths make the most sense because they are using a more efficient way to get the desired result. When it comes to laser engraving, things do start to change. Laser cutters are happy for engraved images to be either Vector or Pixel-based, but it is important to keep in mind that laser time is expensive. A simple logo might take 3 seconds to engrave as a vector outline, whereas the same object as a Pixel image could take 10x as long. This is because to engrave the Pixel version, the laser has to move across the whole image area from top to bottom; a greater distance than tracing the actual linework itself.
So now we know that Vectors are defined conceptually, in a mathematical space, whereas Pixels exist in a literal space within physical confines. The key difference that results from this is that vectors operate independently from the image resolution, and can allow for more cost-effective laser cutting. Pixel images enable a more detailed, photographic outcome – but this comes at a cost in terms of file size and (importantly for laser cutting) time in the laser cutter.
Here’s a video you can watch that helps clear up some of the mystery when it comes to understanding vector and pixel artwork.
Having already received a tremendous response to their original Kickstarter campaign, the team from Ugears are not resting on their laurels… they’ve hit the ground running with a 40% increase in production capacity and the enquiries keep on flooding in. So for those who love to marvel at laser cut mechanical wonders, you still have a chance to jump on board the Kickstarter train with a time-limited second round campaign.
Be quick though, because the promo-priced gears stop rolling on January 12!
Who are UGEARS?
Watch the video below to see what UGEARS is all about. You may think you’ve seen impressive laser cut mechanical devices before, but these guys take it to the next level and beyond. Imagine what would happen if you merged the finicky precision of a Swiss watchmaker with a Dad’s club of enthusiastic 21st-century digital makers. A true labor of love, the first model took two years to develop before it was considered ready for production. During this time, the ideas kept flowing and the result is a growing collection of additional products from a tractor to a working safe, a timer to a model dynamometer and no less than 8 other fully functional laser cut plywood whimsies in between.
“Mechanisms have become so tiny. They are hidden so deep inside things that people do not see the whole beauty of rotating gears anymore. What if anybody could get a chance to create a mechanism?”
The second-chance Kickstarter campaign concludes on January 12, and then once the dust has settled, the official UGEARS store will open for business around mid-2016. So if you can’t wait until then, make a pledge on Kickstarter before it’s too late.
Also, it’s good to see these guys are steadily working through their long list of ideas for future mechanical marvels. Head to the UGEARS Instagram for a taste of what they are working on.
However, after working with Drownspire to develop their Vambit toy into a product for a giveaway at Makerfaire, it soon became apparent that you can successfully use nodes when making with acrylic.
Nodes in Acrylic: Two tricks to getting it right
Firstly the nodes need to be a bit smaller; something in the realm of <0.15mm/0.006″ on each side. This means they won’t cover the same range as when used in wood but they still remain a good option.
Secondly, how you treat the end of the slot is the key. If you have a sharp corner, which is typical in a laser cut slot, the acrylic will always fracture at that point. See this example:
Effectively a sharp corner is creating a weak point in the acrylic. Not such a good thing when this is an important structural part of the design! A small radius in that corner can do wonders to transfer the forces from one face of the hole or slot to the other, and reduces the risk of the material splitting at the corner.
How large should they be?
The larger the radii the stronger it will be so you will need to make an aesthetic decision on how big you can go. On the Vambit the radii was tiny, at just 0.26mm, and it was enough to make a noticeable difference. We suggest aiming for 0.5mm and greater if your design will allow it.
Where to place the nodes
Another trick to keep in mind is putting the nodes on a part of the design where you can guarantee the length. That way you don’t need to bet on the thickness changing and the range of variation is a lot smaller. This occurs when you have 2 edges that are cut by the laser that are the friction edges. This works if you are using tabs but is not necessarily the case if you are using a slotting joint.
For example, in the design of this spinning top Dan put the nodes on the tab as opposed to on the slot.
The tabs on the triangle parts fit into the slots on the circle part. Dimension X and Y will be the same each time as cut by the laser, therefore he put the nodes on these parts. Had the nodes been positioned on the slot for the handle (as in diagram below), the friction points would be against the surface of the material, a part that can vary if the thickness varies.
Other types of connections
An alternative joint is the t-slot joint which is popular with people who make more engineering-type products. This joint uses tabs to locate pieces then a t-shaped slot with a captive nut. This type of joint is great. You can slightly oversize the holes to allow for oversized material and the bolt will hold it snug together. If you use the radii on the corners of the cut outs you greatly reduce the risk of cracking the acrylic by over tightening the bolt.
If you want to go another step, rubber washers can also reduce the chance of over tightening and maintain tension in the bolt so it won’t come undone through vibrations etc.
Hopefully these tips will help you with your next laser cutting project, or perhaps give you the extra tools you need to finalize a design you’re working on.
We’ll be interested to hear your experiences using radii too, and any other advice you might have for people wanting to make 3D designs using acrylic. Let us know below!
