Adobe Creative Cloud updates include 3D printing in Photoshop

Adobe has added a number of new features for its Creative Cloud software suite, which includes Photoshop, Illustrator and InDesign.

The new features include Perspective Warp in Photoshop, which can adjust the perspective of an object so you can match it to that of an existing background; a new Pencil tool in Illustrator; and for InDesign, simplified hyperlinks and the ability to automatically install fonts from Typekit (another Creative Cloud service) if they are missing from the document.

The most intriguing new feature though is 3D printing support in Photoshop.

3D printing is not new; it has been around for many years in industry and medicine. More recently though, 3D printers that are affordable for hobbyists or small businesses have become available. There are also services like Shapeways which let you upload 3D designs and have the model delivered to you. Picking up on this new momentum, Adobe has added to Photoshop the ability to import a 3D design from a modelling tool or perhaps a 3D scanner, and print to a local printer or to a file for upload to Shapeways. Photoshop, according to Adobe, will do a good job of ensuring that models are truly print-ready.

After opening the design and applying any changes needed, such as altering the shape or adding colour, you can use the new 3D Print Settings to print the model.

Photoshop is intended primarily as a finishing tool, rather than for creating 3D models from scratch.

Here are some actual results:

3D printing support is now built into Windows 8.1, but Photoshop does not use this. Apparently the Windows feature arrived too late, but will be supported in a future release.

Adobe says it is bringing 3D printing to the creative mainstream; but to what extent is this a mainstream technology? The hobbyist printers I have seen are impressive, but tend to be too fiddly and temperamental for non-technical users. Still, there are many uses for 3D printing, including product prototypes, ornaments, arts and craft, and creating parts for repairs.

Two ways to make a spoon: 3D printing in action

1 Comment

Last week I attended the Monki Gras, a distinctive event exploring how to scale craft, mainly in the context of technology but also in the context of beer.

On the second day there was a light-hearted competition. Who can make a spoon faster, a wood carver, or a geek with a 3D printer?

A skilled craftsperson can make a spoon in around half an hour, we learned.

In the other corner was a techie, a laptop computer and a 3D printer.

Said techie (I did not get the name unfortunately) had downloaded a spoon design from the internet and was printing it on a Prusa Mendal RepRap machine. Cost: from a few hundred pounds if you self-assemble, or £1000 or more if you purchase complete.

The software is open source: slic3r to convert a 3D model into printing instructions, and pronterface to talk to the 3D printer.

Looking in more detail at the printer, what you have is a system of cogs, rails and stepper motors that lets a print head move in three dimensions. The raw material is a spool of green plastic from faberdashery. This could be fed from the rotating white spooler at the top of the machine, though in this case only a little was needed and it was floating loose.

The plastic is melted by the print head and squirted out to form the object being printed. Apparently once formed it is reasonably rigid and strong.

Attendees observed that the competition was pretty silly, since speed is not a goal of 3D printing (and the wood carver was indeed the victor). In that sense, 3D printing is a poor way of scaling craft, though it has some potential in that a brilliant design can be reproduced as an object many times over. If you want a lot though, it is worth investing in traditional plastic moulding: setup is expensive, but once you have done one, you can do thousands more cheaply.

Still, imagine what 3D printing enables. I have a nice set of headphones, for example, which are useless because a small plastic component has broken. If I can get hold of (or make) a 3D computer model of the part, I can now make that part for little cost. You do not even need your own 3D printer; services like Shapeways let you upload the design and get the part in the post a few days later.

In niche areas like model trains and landscapes, 3D printing makes models viable even if only a few are needed. You can also have exactly the size you want, rather than being restricted to the standard sizes that are volume manufactured.

For inventors, 3D printing makes prototyping easier. You can iterate through hundreds of slightly different designs and try them out physically, rather than relying on computer models.

The opportunities are fantastic, and you can get started for little cost; though the guy at Monki Gras did note that his RepRap was temperamental and therefore a high maintenance gadget. Maybe by making a few modified parts he can improve it.
