The blade of a utility knife is easy to replace at the first sign of dullness, and it can be used for a multitude of other things. In any case white mountboard tends to be cheaper and some brands are softer to cut. It is surprising how many people who might in other respects be very able with their hands find it quite difficult to cut a straight, clean line. From my experience of witnessing people trying to cut a straight line (must be easily in the thousands by now!) Don't waste your money on it, it's extremely slow. Some brands of this type of foam glue very readily with superglue. Just cut enough to be able to bend it backward. It helps even more if the height indications included on the drawn ground-plan are kept visible .. another good reason for using the actual ground-plan, pasted to the baseboard. Gluing It is often necessary to make parts of the model removable so that, especially, interiors can be better seen and to take better photos of these parts. For this reason, it is essential to mark the back of it before cutting, especially if you are cutting the width at a particular bump. Even at the later stages of design development it pays to be truly creative with the model, to be inventive with methods of representation or ‘simulation’. Less obvious, isn’t it? Strong PVA glue (always better to use the ‘wood glue’ type rather than the economy-style ‘school’ glue) will bond foam-to-card well but not instantly, so joints often have to be temporarily taped together with masking tape while setting. The designer may build a version earlier in the design process to test the design’s three-dimensionality ( to check general proportions, to better visualise filming possibilities etc.) Superglue for example will ‘fog’ acetate around the area glued while both the ‘cement’ intended for plastics and UHU tend to be difficult to control. with my own little twists to it. Take your time, and cut very slowly and acurately. I would suggest you use it sparingly until you’ve mastered how to achieve perfectly clean, straight cuts. On the one hand a good, robust, polyurethane-core foamboard is invaluable as a lightweight baseboard .. but if a cheap polystyrene-core one is used it is liable to warp badly over time and ends up showing every finger impression! The material needs to be cut half-way through in repeated parallel lines (as little as 2mm apart for a tight curve), making it more flexible. White foamboard is one of the most common materials used as a structural basis for Also, whatever you decide to cut with should be held as horizontally as possible. This common ‘expanded polystyrene’ is often shortened to ‘EPS’ whereas styrofoam is officially ‘XPS’ meaning extruded polystyrene. If you’re lucky, slight changes in level are easy to achieve just by layering different thicknesses of card on top of the baseboard. with a try square) to the other side and completing the cut in exactly the same place on this side. Expanded polystyrene is basically the same substance but formed differently and the cells are much larger. Having to flip little bits of cardboard open in the model just to show that they open seems a bit unnecessary and could even be dangerous to the model if nerves are affecting one’s motor-control! Foam board can sometimes be referred to as foamcore but, no matter which name you call it by, you might know from experience that the edges love to get jagged when you try to cut it. And a terrific companion to my Roman Gladius sword project. However, if the radius is large enough, you may be able to skip this step. The material may also be familiar from exercise or camping mats. Although very soft it can be cut quite cleanly with a sharp scalpel though it can’t be sanded. One possible way of solving this is by cutting just half way through on one side, taking the line carefully round (i.e. Coating any foam edges first with slightly diluted PVA will solve this and when dry, UHU or sprays can be used on these edges, but it is rather laborious to go to this trouble. It gives an overview for the technical crew responsible for building and furnishing a set (or modifying an existing one) of how much work is required. Examples are Kapa-line foamboard and London Graphic Centre’s Premier Polyboard. The best option is undoubtedly a utility knife with an X-Acto knife being a close second. Otherwise, the model can become chequered with distracting areas of black. To cut foam board straight, start by making sure you measure and mark a straight line. the underside to make it so) and positioned so that the main light source is falling into the cutting edge, so that the marked line is not obscured by shadow. I have fully updated this article, which was originally written a few years ago, and I have added some more illustrations. Styrofoam may be familiar as the light blue sheets (although styrofoam comes in other colours according to different grades or densities) made for wall insulation and commonly used in theatre and film workshops as a rapid carving material. FOAMULAR 150 1 in. Take the second piece of foam and place it on top of the first with the glue and using some long pieces of wood clamp down the two sides of the foam with clamps. This would then need to be made detachable. One exception to the ‘5cm rule’ may be the floor area .. and this calls for the personal judgement of the designer/maker. This is yet another solid argument for starting the physical model process early on, if only as rough ‘sketch’ version. Especially if two larger pieces are being laminated (i.e. Foam board is one of the most popular types of signage that you’ve probably seen in your local supermarket or in malls but probably never knew the name. The 300gsm is roughly 0.5mm thick and the 600gsm 1mm thick. Bend your Styrofoam piece if you require a curved shape for your project. There should be a unity .. or rather, the word is homogeneity .. of colour and treatment throughout the model. But it should show very clearly where the floor is ‘the set’ and where it is not, so sometimes it makes sense for the ‘offstage’ to be differently coloured. It serves as a communication to the whole film crew. Using a solvent glue such as UHU may be quicker, but it dissolves the foam in the standard brands so clean or effective gluing is not always guaranteed. I’ve written elsewhere that I don’t consider pure white card to be the right medium at all when it comes to representing, or even just mocking up spaces. Some have built that down around 4 oz. An effective and often easier alternative however is to draw these structures with permanent ink on acetate sheet (but the acetate should ideally be matted to differentiate it from glazing). By the way, another misunderstanding often arises when confusing dimension and surface area. However if the foamboard is warped (and the cheaper polystyrene core foamboards often are) this must be first corrected by firm bracing on the underside. Model in preparation for the build of the Sarang moon-station for the film ‘Moon’ 2009 on Shepperton Studios K-Stage. If you use a hot knife or a hot wire, be sure to check the type of foam that you are using to verify that it is safe kind to be cut by these. Showmanship may not be strictly necessary in practical terms .. but it can inspire!  Even this kind of model can be stylish as well as functional and, dependant on individual taste, ability and.. most importantly.. time, it can be embellished with graphic detail, structural finesse or effects designed to ‘sell’ the visual concept. This form of model-making is, I think, still proving itself invaluable despite increasing competition from the likes of SketchUp. 5mm at 1:50 scale represents 25cm). It is understandable because making them can be tedious, but ‘sandwiching’ foamboard or card to form the correct ‘riser’ (meaning the height of a step) and then simply layering these is one way of making construction much easier. glued surface-to-surface) only spots of glue are needed to hold them firmly in place otherwise the water-based glue will cause warping if spread on too liberally. And put a pin on each end like this. Make a Roman Scutum . Interesting process for easily getting a beautifully curved shield. Bending Whether curved walls need to be made in either foamboard or mountboard the method is similar. This is the normal size sheet (20 inches by 30 inches and 5mm thick). Be sure to select boards with fairly straight grain and no knots so they can bend without breaking. Cutting Foam Board Insulation. Because of the board's excellent thermal properties, you can use thinner foam boards in place of thicker foam boards made of polystyrene and polyurethane. For more on how to shape styrofoam, including concave as well as convex forms, see my article Shaping styrofoam under ‘shaping’ in the Materials section. Usually the minimum quantity one can order is an 8x4ft sheet (1220x2440mm) which can be quickly delivered, but if one accepts this the price of 1mm or 2mm Palight can work out cheaper than most forms of cardboard. The ‘white card model’ of the present context is, in many ways, anything but rough and inexact and most often, due to its usual place in the chronology of design steps, it is no longer exploratory. working or moving elements) such as doors, shutters or removable parts need to work in the model, or at least be clearly indicated as movable. Since white card models Only a little is needed, which is drawn into the joint by ‘capillary action’. These foams are very easy to cut with a knife (or hot wire cutter, except PU foam) and both styrofoam and PU foam can be sanded effortlessly to a smooth, sharp finish even for very small forms. I’m keeping it in the Methods section for the time being, though not sure whether it shouldn’t go with Technical Drawing. It will not warp as much as other types of card when painted. Although it contains oil it can be painted with water-based paints or glued using Pva quite easily. of plastic together. I will be coming back to these later, but for the moment we are still concentrating on white card models for physically built sets. But the grooves only work for bending one way, so for example an ‘s’ curved wall has to be grooved in alternate positions on both sides for it to bend properly into an ‘s’. You will be able to tell if a knife is genuinely sharp or not when it comes to foam board because a sharp knife can slice through the whole thing in one smooth cut. Courtesy HBO ‘Boardwalk Empire: Designing an Empire’. These are quite strong, but also suitable for delicate cutting. Foam boards are frequently used by architects to make models of what they plan on building, to create signs or posters, as a form of insulation, or any number of other things, each of which needs the edges to have a sharp, clean finish. When the ceiling becomes a feature of the design it should definitely be included, but again detachable. Since the white card model is commonly a pasted, 3D version of the technical drawings  one would assume that these dictate the scale of it .. but this is only partly true. and it maidened at 10 oz. This has to be done carefully because there is no chance of repositioning.
