How To Make Laser Cut Interlocking Acrylic Designs

The Importance of Radii

We’ve written about using ‘nodes’ with 3D objects made from wood before, but suggested it may not work for acrylic because it is more brittle and tends to be less forgiving.

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!

Cool Conference Swag You Could Laser Cut For Pennies!

Packing for a conference is a lot like packing for a hike.

You have to pack the essentials, you want to pack a few standby items and you’d like to bring certain vanity items along, just for the heck of it. But as you pack, you also need to keep a check on the weight of your pack. Plus, unlike a hike where you probably won’t encounter more than one or two people at most, a conference is full of people who are eager to hand you bags of stuff!

Yet before you begin rummaging through conference bags for stuff to keep, here’s a quick list of things most attendees wish they had brought along which can be laser cut really cheap.

Simple Conversation Starters.

Lasercutwristband

Laser Cut Wristbands.
While you will do your best to network before the session and during the breakout periods, the fact is you won’t be able to approach as many people as you’d like. But rather than rush through conversations with multiple people, you can use a little laser cut panache to draw people to you.

If designed well, this is bound to get you noticed even when you do something as simple as answer a phone call. It also helps you stand out in a crowd by acting as a distinct visual marker. Within a conference setting, you get instantly noticed if you have to raise your hand. And finally, it can be a great way to share your personal details without having to repeat them over and over (just in case your name or email has a complex spelling). Plus, if you run out of business cards, or don’t feel the need to share a business card with certain people … you can redirect them to your wristband for your details instead of the awkward fumble for a pen and napkin.

Things That Make You Memorable.

How To Create Strength Using Origami and Laser Cutting

New structural options from everyday materials 

In recent years, the boundary between art and engineering has continued to blur with scientists and researchers turning their formidable minds toward traditional craft techniques. The results are starting to get quite exciting, with surprise breakthroughs such as the Japanese origami-inspired ‘zippered tube’ featured above demonstrating that there is still much to learn about how we use familiar materials.

This example highlights a novel process of combining thin flexible sheets of material that have precise cuts and folds in them. The location and combination of these elements enables the material to become rigid when assembled in specific configurations, gaining structural integrity far beyond the original material’s capacity.

The research that developed this construction technique emerged from a collaboration between University of Illinois grad student Evgueni Filipov, Georgia Institute of Technology professor Glaucio Paulino and professor Tomohiro Tachi from the University of Tokyo.

“…we’re starting to see how it has potential for a lot of different fields of engineering” – Evgueni Filipov

Filipov and his colleagues focus on an origami technique known as Miura-ori folding, where a tube is constructed from two precisely folded ziz-zag strips. Individually, the strips are highly flexible but when combined the resulting tube has a remarkable rigidity and controllable degree of compression or folding.

What does this mean for Ponoko users? While much of the focus in the origami research is currently centered around potential uses in architecture and for space exploration; many of the options from the Ponoko Materials Library would be a great fit for this approach to assembly and construction.

How To make a Laser Cut Local Landmark

City of Bath Georgian House flat-pack model

Pitch_26_Bath_Terrace_House_1024x1024

Miniature models of local landmarks are a popular choice when it comes to souvenirs and keepsakes. In this example, the iconic Georgian terrace houses from the city of Bath in the UK are recreated with loving attention to detail.

Available as a flat-pack kit of three neatly stacked cosy homes, you can choose from either 1.5mm card or 3mm poplar ply, and the straightforward assembly process will only take a few minutes.

Ideal for Laser Cutting
Laser cut architectural models are the ideal choice to make use of tab-and-slot construction techniques that allow for quick and easy construction, often holding together without the need for glues or adhesives. Basic elevations of the structure can be traced out in your preferred drawing program (inkscape is a Ponoko favorite) and prepared for laser cutting. Take the guesswork out of designing with interlocking slots using one of several freely available tools and plugins. For a landmark or object with a more sculptural form, 3D models can also be sliced up into panels or interlocking sections that are just right to send to the laser cutter.

Optimise for Production (and add a little extra)
Once you have the profiles and parts that make up your object, arrange them neatly within one of the Ponoko laser cutting templates and add useful notes or assembly tips as etched details. The Ponoko guide to keeping laser cutting costs down contains important information that will save you time and money, so be sure to read through before starting to avoid common (and costly) pitfalls.

It can also be nice to add a little something extra to the assembled model. The Georgian terrace kits by Bob Kann come supplied with a little light to install inside, so that there is a warm welcoming glow that completes the homely feel.

How To Help Your Client Launch a Kickstarter Campaign

Head off Crowdfunding questions with these useful tips and resources

kickstarter-help

Crowdfunding campaigns give entrepreneurs, artists and businesses a unique opportunity to test the viability of their ideas. Yet for many, the thought of running a Kickstarter campaign can be a daunting prospect.

So how can you help de-mystify the process, and give your client the tools and support they need to embrace all that Kickstarter has to offer? Let’s take a look at some of the contributing factors that enable campaigns to reach – and indeed exceed – their funding goals.

Choosing the right platform
The first question to ask is whether or not this method of raising funds is actually suitable for your business proposal. Each crowdfunding platform has its quirks and benefits, and in the example of Kickstarter, many submissions do not even pass the approval phase. It is well worth taking the time to identify which crowdfunding option best suits your business model and potential project outcome.

Don’t be dazzled by dollar signs – just because there are campaigns raising millions of dollars does not mean that every campaign will be an overwhelming success. For the majority of campaigns, a few thousand or even just a few hundred dollars over the target amount can be a big deal.

Be prepared to work hard
Although crowdfunding has been shown to be surprisingly lucrative for some, successful outcomes are not guaranteed. It takes more than just having a bright idea; you have to know your project very well and be prepared to put time into every stage of the funding process. Understand that for every hour you spend (and there will be many!) on preparing the campaign, there will be just as much time required to maintain and promote the project through to completion. Yet even then, your task doesn’t end when the countdown stops. Assuming you are sitting on a pile of money after a successful campaign, you will need to get moving on production and manage the distribution of rewards to your backers.

There is a misconception that a crowdfunded campaign is something that can be done on the side, in your downtime or on the weekends. This is simply not true… one thing that all successful campaigns have in common, regardless of funding levels or project outcomes, is that the campaign itself was a full-time commitment.

Engagement 
There is a strong social media component to the Kickstarter process, with communication and personal interaction playing a large role in backer satisfaction. It can help to remind yourself that Kickstarter is not an online store, even though some backers continue to treat it like one. Integral to successful campaigns is the way people love to feel like they are involved in making things happen. This is a different consumer experience than traditional online shopping, and with careful planning you can use that to your advantage. Choose a variety of rewards including smaller contributions that can help keep people interested in your progress, even if they aren’t in a position to commit larger amounts of money during the campaign. These potential future customers can become informal brand ambassadors through their own social media activity, expanding your reach before the campaign reaches its conclusion.

Be realistic
Not all campaigns are successful, and that is ok. The reasons why a campaign does not reach its funding goals can be quite varied, and are sometimes just as mysterious as to why other campaigns dramatically exceed expectations. When setting up a crowdfunding campaign, plan out how you will navigate through both failure and success, so that your business can continue to evolve beyond the campaign timeline.

Assistance
Don’t be shy – a Kickstarter campaign is a lot to take on, and it is perfectly ok to seek out help. In fact, many services are popping up that enable a streamlining of each aspect of the campaign. Gathering and processing information beforehand will help to protect you from nasty surprises and also empower you to fully exploit successes and opportunities should they come your way. Here are a few to start you off:

Keeping it Social: Leveraging Social Media for Product Promotion

social-media-icons-2

Automation. Some love it. Some dread it. But no matter which camp you belong to, there is no denying its power to make our lives easier in some ways. One clear avenue for automation success is social media. Today, the width and speed of social media channels has far surpassed the reach and (in many cases) the efficacy of traditional feet-on-street marketing.

Yet, for many marketers, leveraging this growing resource can feel daunting given the number of choices and the understanding necessary to maximise the potential of each channel. But as we’ve learnt through our own experience, if you plan carefully the results can be stimulating and the process a lot of fun. Through this blog, we’ve tried to distil our understanding of everything we’ve learned (and are continuing to learn) along the way.

Understand your choices
With so many options out there, choosing the right one for your business can feel like an overwhelming experience. But, to avoid information overload, we feel the best way to get things moving is by starting small. While the temptation to jump into every platform will be strong, learn to exercise restraint and be selective about which platforms you choose. Also, take the time to monitor each channel to understand whether they are bringing in positive results for your brand.

Let’s take a look at the recommended options:

How to use laser cutting to stand out from the crowd

new-blood-laser-cut-1a

The distribution of ‘freebies’ or giveaway items can be a powerful marketing tool, with novelty objects triggering conversations between stakeholders in new and interesting ways. When used to full effect, these products become memorable in their own right… and most importantly, that also means the brand identity becomes an integral part of the ongoing conversation.

For an exhibition showcasing the best student works titled ‘D& AD New Blood’, the creative design team from Southampton Solent University incorporated visual, conceptual and sensorial metaphors into their very effective event freebie. A neat little laser cut box was produced in the style of the ubiquitous Southampton dock packing crates. Inside, further supporting the theme of “Cargo”, nestled a macabre-looking glass vial with the top sealed in wax.

new-blood-laser-cut-c1

This small bottle of wine continued to play on the New Blood idea of creative juices being shipped out. All sealed in a laser cut crate with sliding lid and laser etched details, it held just the right combination of conceptual nostalgia and contemporary novelty to become an effective conversation starter. People loved the diminutive scale and the nonsensical utility of the object. This was all made possible through clever use of laser cutting to increase brand awareness. See more photos of the miniature crates on behance.

How to Decide When the ‘Price is Right’ in your Retail Strategy

 

Screen Shot 2015-09-08 at 3.44.45 PMPricing your products can be an exciting time as you begin to imagine the cash registers ringing. But when you actually get down to it, the initial excitement often gives way to doubt and nervousness.

Suddenly your mind is racing with questions and explanations – What if you price too low? You might make a ton of sales but still end up alarmingly short of money to cover your expenses.

On the other hand, what if you price your product too high? You might convince the market you are a high-end, luxury manufacturer. It might even begin to draw a financially upmarket range of customers. The high cost may offset your smaller sales figures, but what if the market shifts? What if a change in manufacturing or a new competitior can match your level of quality and reduce the price? Can your businss compete and survive in a price-sensitive market?

Such questions and more will always be floating around and no one strategy can magically address all your pricing doubts. However, by being aware of the options available for retial pricing, you will be in a position to choose the one which suits your business when the time comes.

Before we go into specifics, there are some basic overarching categories which classify individual pricing strategies. These include:

  1. Demand oriented strategies: In a retail environment, you don’t always have to depend on your skills as a marketer to attract customers. Some porducts, or even categories of products, have such a magnetic pull that setting the retail price for them can be done simply by observing demand.
  2. Cost oriented strategies: This is a more common format for calculating retail pricing and revolves around the relationship and ratio of merchandise costs, operating costs and expected profits.
  3. Competition oriented strategies: These strategies involve observing, analysing and responding to market changes to maintain the perception of competitive pricing at all times in a given market.

Let’s begin by looking at some common demand oriented strategies:

Manufacturer Suggested Retail Price (MSRP)
As the name suggests, this is a price manufacturers recommend retailers use to sell their products. This strategy is used by manufacturers to standardize prices of products across multiple locations and retailers.

However, MSRP can also be used in a market where there is high product demand. In such a market, by sticking to the manufacturer’s price, the retailer can drive higher profit sales and determine what the price levels of certain products will be in his store, irrespective of the consumer’s bargaining power.

Demand Ceiling Pricing
In this form of pricing, the retailer takes into account the maximum a consumer will pay for a certain item and as far as possible, try to keep the price up to that level so as to maintain a demand momentum for that product.

Demand Floor Pricing
Here, the retailer takes into account the lowest he is willing to go on price to meet demand for a particular product. This is usually done on lower cost items where a retailer might go lower on the cost to keep the volume of demand constant for longer.

Odd Pricing
Studies have shown that when customers spend money, they actually feel a sense of loss. But if you help minimize this feeling of loss, it is possible to nudge customers into making a purchase. In retail, you can do this by ending the price with an odd number like 5, 7, or 9. For example, using $8.99 instead of $9.00.

Also if you want to know the ideal odd number to pick, it’s 9. A study conducted at MIT and the University of Chicago ran an experiment on a standard women’s clothing item with the following prices $34, $39, and $44. The item priced at $39 outsold even its cheaper counterpart price of $34.

Zone Pricing
It’s no secret that certain suburbs or geogrpahical areas house more affluent people. In such areas, the demand for certain types of products or categories will always be high, simply due to their increased ability and propensity to spend. Using this tactic, retailers can map out certain areas where they can get away with charging more for the same stocked item as compared to stores in other locations.

Now, let’s examine some cost oriented pricing strategies:

Multiple Pricing
This is a common pricing strategy wherein you can sell more volumes of smaller itesms simply by grouping them together. It’s a strategy you normally see in grocery stores and even across clothing brands espcially for smaller things such as socks, underwear and T-shirts.

Discount Pricing

All customers love agood bargain. That’s why sales, discount coupons and even holiday deals are so popular. The only thing to consider is why you’re choosing to discount your products. If it’s for more footfalls, consider going wide with your discounts so as to attract a variety of people. If it is to get rid of unsold inventory, try setting a time limit on your discount (1 day only, flash 12-hour sale) so as to not draw too much attention to the items on sale. And if you’re trying to attract price-conscious customers, club your discounted items together to seem more appealing.

Loss-leading Pricing
If you’ve ever walked into the store because you saw a ‘too-good-to-be-true’ discount sign but walked out with three things, you’ve just experienced loss-leading pricing at work. The idea is once you get a customer in store to buy one item, just looking at other items on the shelves is often enough to drive more sales.

Finally, let’s examine competiton oriented pricing strategies:

Below Competition Pricing
As the name suggests, retailers employing this strategy use a competitor’s pricing data as a benchmark and consciously price their products below them to lure consumers into their store, instead of the competition’s.

Above Competition Pricing
While below competition seems like a no-brainer, retailers need to be cautious before using this strategy. That’s because if your competition is willing to go head to head, he might keep dropping his prices to the point where it’s no longer financially viable for you to go any lower. A good example of this is Amazon who brought the cost of paperback books so low, they put Barnes & Noble out of business.

Instead, retailers can do the exact opposite – benchmark their product at intentionally higher prices than their competition. This forces customers to stop and consider why your prices might be higher. And, not surprisingly the conclusion most arrive at is – your produt must be of higher (and therefore better) quality. A classic case of this strategy working is Starbucks, where people consistently pick them over Dunkin’ Donuts.

One of the most exciting and nerve-wracking aspects of retail is determining what price to sell your products at. However you must remember that pricing is both an art and a science. It requires an experimental attitude and an intuitive feel for how you want your brand and, by extension, your products to be perceived.
