Silhouette Portrait 2 cutting plotter for scale modelers
Some time ago there was an article on iModeler regarding use of a cutter (or cutting plotter) for our hobby. At that moment, I was thinking about this for a while, especially because of my previous experience – I saw cutters in the late 90’s when I was working in an advertisement. The idea of having a tool for making custom masks was attractive, also taking into account how much I “like” doing this type of job. And finally, after I’ve again got issues with accuracy and dimensions of a painting mask I’ve bought, I’ve decided to buy a small desktop cutter. Honestly speaking, I didn’t spend much time searching, reading, and comparing. I’ve just bought the cheapest cutter from a well-known brand – Portrait 2 by Silhouette. I’ve got some Oramask 810 masking film, also used by some manufacturers like Montex or Pmask, and my first successful try out was with Swiss crosses for my Bf 109G. So it works.
As you can see, this is really a desktop cutter, with a size of a full-sized keyboard. It comes with one blade, and an adhesive cutting mat – it’s not needed for a vinyl masking film, but for a paper or fabric, it would be useful. There is an option to connect it via Bluetooth, but I didn’t try it yet – USB cable is OK for me.
Portrait 2 is a quite noisy tool – if you remember matrix printers, you know what I mean. The principle is the same – the paper sheet is rolling back and forth, while the blade is sliding in a perpendicular direction. Bundled software contains not only hardware drivers but also a visual design tool for creating your own shapes – Silhouette Studio. Unfortunately, the free version has some limitations, but I will talk about this later.
Masking tape or film. Maybe, the most famous one masks, which is made by Eduard, are done with a Kabuki tape. I think it’s the best choice for masks because it’s a very flexible and soft material, so it’s good for curved surfaces. If you’ve ever used masks made of thick black vinyl tape, you know the difference. But the issue with Kabuki – the price and availability. In the opposite, it’s really easy to buy a special masking film by Oramask (I believe, it’s a subdivision of Oracal), designed for hobbyists – Oramask 810. This is a thin semi-transparent self-adhesive vinyl film. It’s much cheaper than Kabuki but still good enough for our hobby. But anyway – there is a choice.
After the first try out, which was an easy one – just circles and crosses, I did want to try some more complex design – masks for canopy. For experiments, I’ve taken an HobbyBoss MC.200 Saetta canopy in 1/72 scale. I’ve tried to make this design with a bundled version of Silhouette Studio, and I’ve failed because of several reasons – the editor lacks some functionality, needed for this, like tools for fillets, chamfers, and other special drawing features. So, you need some other editor, but the next issue here is that free version of Silhouette Studio doesn’t have an import/export feature enabled – no way to import an SVG or DXF file. That’s a real issue because Silhouette Studio is not only a drawing software but also an interface for a cutter itself. Portrait 2 will not work as a regular printer.
You need to buy an extended version of a software or use some alternatives. One of them is a special export plugin for Silhouette cutters made for an open source vector graphics editor Inkscape. I was using Inkscape both for designing the masks, and for the cutting process. Please note, that use of a 3rd party software is totally under your own risk.
As you can see here, you can control the pressure, speed, and some other parameters.
And the final result.
But even without additional software, it’s possible to cut some general shapes, like circles, stripes, ellipses, etc. The smallest circle on a photo has 2mm in diameter, and stripes start from 1mm.
The funny thing is that I’ve spent more time doing the design and test cuts, compared to just doing masking in a regular way with Tamiya tape, knife, and templates. But the final result is more precise, and the best thing here is that you can easily share designs with other people. Because it’s not only about canopy masks but also about national insignias, numbers, lettering, camouflage patterns, and it would be great if the community will create and share such things – it’s a digital era, we should all benefit of it even more than today.
PS. Next big thing is a 3D printer 🙂
PPS. If you need this MC.200 masks design – you can write me here and I’ll send you the file, because it’s not possible to attach SVG file to a post. It’s licensed under the CC Non Commercial license, so it’s free.
PPPS. Just a side note – I use plastic tweezers for microelectronics to not damage the clear and plastic parts. I’ve found this very useful.
