It’s astounding to think that up until just a few years ago, the idea of being able to print out any real, physical object you could imagine – all safely at home – was mostly considered the stuffof science fiction. Though the earliest 3D printing technologies can be traced back to 1986, when the first patent was issued for an SLA apparatus invented by Charles Hull, it was not until January 2009 that the first commercially available consumer 3D printer, the BfB RapMan, was put up for sale. The move was like the start of an avalanche. Soon, projects like Z Corp’s Spectrum Z510, RepRap and MakerBot’s Cupcake CNC kit began to change the world for good. 3D printers could be bought to use in anyone’s living room or office,…

Plaster printers use a plaster powder which is covered with a binding agent, normally water, in order to create the solid object. They use the same technology as a normal 2D colour printer to draw out each layer in turn, and in some cases the printer uses a very similar nozzle to the ones found in your desktop printer at home, as they are able to print on a flat plane in full colour. As plaster printers are powder-based, like SLS printers, the parts are self-supported and therefore you are able to make significantly more complicated shapes with them. A dye is also added through the binding agent, which allows the printer to make parts in full colour. For a while this was the only way that you could 3D…

FILAMENT MAINTENANCE There are a few essential things to keep in mind when handling and storing your filament. Make sure that once you have opened your filament, you store it somewhere cool, dry and free of dust. The printer’s extruder is very sensitive and as such even small bits of dust can lead to clogging. Dust will accumulate on your filament over time if it is left in the open. Prevent this by keeping it covered. Filament can also become twisted if not cared for properly. Make sure that when you are loading and unloading a spool of filament that you are very careful not to let it unwrap and start tangling. This can lead to a lot of wasted filament. UNDER EXTRUDING OR NOT EXTRUDING AT ALL Generally these…

While there’s a huge amount of free models available online, and a massive community that continues to churn them out, you might want to consider actually making your own models for 3D printing.

For this tutorial you will be learning how to take your scan and clean it up so that it is ready for 3D printing. Nine times out of ten you get a scan that is messy, so knowing how to clean things up is a great skill to have because you will want to ensure that you get as much accuracy and as little noise as possible in your model. Here we are going to focus on sculpting a 3D-scanned bust in ZBrush by importing the messy broken scan and re-working the model. We’ll also look at how to capture final details using some of the reference images that you took later in the scanning process – you should make use of these references as frequently as possible. Particular attention…

3D printing has become a hot topic recently and many people are beginning to realise the benefits and possibilities that it has to offer. With more people looking to take the leap and invest in, or start using one, it seems pertinent to address the questions of what exactly a 3D printer is and does. 3D printing is the process of building something layer by layer. It doesn’t matter which form of 3D printing or which technology is being used, this fundamental principle stays constant. There is a general misconception that all 3D printers are the same thing – this is not the case at all. Each printer and process will come with their own challenges and key principles that need to be followed to get the best out of…

PLASTICS You’ve done the hard part and decided which 3D printer you’d like to try. The next step is buying the requisite materials for printing, the first being filaments. The most common varieties of 3D printing filament are plastics, typically PLA (polylactic acid) and ABS (acrylonitrile butadiene styrene), and these are both widely and cheaply available on the internet or from specialist stores. There are distinct differences between them, mostly rooted in their strength, precision and melting point. You can also choose from a wide variety of colours to add that little bit more character to your prints, and can even print in multiple colours if your object is separated into different parts and assembled later. There are dual-extrusion machines out there that allow you to print in two colours…

“Modelling is a crucial stage of preparing for 3D printing – after all, without a 3D model you certainly won’t be getting a 3D print!” Modelling a 3D object is the very first stage of what is called the 3D pipeline. You don’t need to worry about this terminology too much, but essentially it is the stage that allows you to block out the object that you are designing, decide on its size and shape, and then add more intricate details before printing. It’s a crucial stage of 3D printing – after all, without a 3D model you certainly won’t be getting a 3D print! It might sound a little complicated, but generally speaking it can be a very simple process. You’re essentially playing with shapes on a computer screen…

Choosing the right software to model potential 3D prints with is a surprisingly personal decision, with different software packages, slicers, and even plug-ins to choose from at a wide variety of price points. If budget is a major factor in your decision, Blender or SketchUp are great, free options. Your personal style should also be a factor. Anyone interested in modelling hard surface designs to print to very accurate levels should take a look at software better for CAD such as SolidWorks; but those more interested in organic-looking designs would be better suited to 3D sculpting packages like ZBrush or Sculptris. Whether you’re modelling an organic character or a mechanically complex vehicle model that needs all the right tolerances, taking a 3D digital design from software to printer requires a…

It is easy to get so caught up in creating the actual shape of a model that you neglect to consider the surface. With some subjects, it is the surface that holds all of the character, such as textured organic materials or glistening metallic objects. Using this tutorial you will learn how to surface model using Rhino as well as how to print with alternative materials like BronzeFill and WoodFill. We will be making a mecha-style model of a rhino head, though the techniques that we’ll use here can be applied to any model and are a good introduction to the type of surface modelling that is achievable within Rhino. We will be modelling surfaces and creating objects that would be very difficult to make in other programs, while still…

“The strength of the finished piece depends partly on the type of plastic filament you use” 3D printing is also called additive manufacturing because it works by adding new material, as opposed to a computercontrolled lathe or laser cutter, which removes it. The earliest system, called stereolithography, dates back to 1986 and uses a resin that hardens on exposure to ultra-violet light. The printer scans a beam of UV light over the surface of a bath of the resin to create a thin layer of plastic. The model is then sunk slightly into the bath so that the laser can add a new layer on top. Selective laser sintering (SLS) works in a similar way to print with metal. The printer shakes a thin layer of metal powder onto the…

“Because they make their parts from a liquid, you are able to get a significantly finer print, with some incredibly detailed parts” Stereolithography (SLA) and Digital Light Projection (DLP) printers are both similar in that they use a liquid resin to make their parts. Because they make their parts from a liquid, you are able to get a significantly finer print and can get some parts that go down to incredibly fine details – some so fine that you would need a microscope to fully appreciate them. They actually print by shining UV light at the resin for long enough to turn harden, in what is called the curing stage. The cured resin is sometimes still a little soft depending on how long it was exposed to UV light while…

“You need to crawl before you can walk so don’t jump into something complicated. Build up gradually – this way you will get to know your particular printer” Don’t be too ambitious for your first print. Start with something simple as this will help you understand your particular printer, as well as identify if there are any problems. If you have built your printer yourself this is particularly important as there are many things that need to be calibrated. Once your prints look the way you want them to (you can download calibration prints to use as a benchmark), you can then move on to more complicated designs. You need to crawl before you can walk, though, so don’t jump into something massively complicated straight away. Build up gradually –…

Free models for 3D printing are abundant nowadays and are offered by a large number of online retailers.

It’s quite hard to go wrong – simply visit the site of your choice, search for something you want and download the file. Always double check that the file…

“From the initial inception to the very final stages, finishing should be considered. It is integral to how well the object will be received” Imagine spending many hours crafting a beautiful piece of furniture and then leaving it bare. If you left it with just the original work in its natural state, it would not looked finished and would be half the object it has the potential to be. For all of the talk and hype surrounding 3D printing, finishing is rarely mentioned, but it remains a hugely important part of the creation process. From the initial inception to the very final stages, finishing should be considered. It is integral to how well the object will be received. You will need to think about sealing, bonding, painting, sanding and other…

In this tutorial we are going to show you how to create and 3D-print a prop, which will include moving parts. Creating an object that incorporates moving parts can be tricky but is often a lot more rewarding. It encourages you to explore the limits of what your 3D printer is capable of and at the end of it you’ll have a finished product, ready to take to your next Comic Con! Be prepared for a bit of trial and error when designing objects with multiple components that fit together; making sure that all your parts have the correct scales and tolerances can involve a bit of work, particularly if you want them to fit together without glue, however once you get the hang of it then it is a…

Due to its ease of production, non-destructive process and high-quality results, 3D scanning is a process that is already being applied to multiple industries. It’s difficult to avoid the technology that has been so heavily featured in the media in recent times; it has been used in the production of prosthetics and bodily organs in the medical industry, CGI in the video game, film and entertainment industries, as well as used in the documentation and archiving of cultural artifacts. 3D scanning is the process of analysing an object or an environment through its form, dimensions and colour. By gathering this data it is possible to create accurate representations of an object. There are various methods in which objects can be scanned, from hand-held real-time to infrared and contact – these…

Siert Wijnia may be the CEO of a globally-renowned 3D printer manufacturing company today, but just eight years ago, his life couldn’t have been more different. A skilled mechanical engineer, he’d been working in a more managerial role at a firm that built large refineries for oil giants like Shell and BP. “I was thinking, what am I doing here?” Wijnia begins. “It didn’t feel totally right for me – it’s just ending natural resources and not going to the next stage by thinking of new ways to do stuffinstead. One day I thought, I can’t change this business but I have a choice in what I do.” Luckily for Wijnia, it was just then that a brand new type of workplace had begun to spring up in towns and…
