Faced with the task of making honey comb a model, you need to decide what material it perform. The choice of material depends on several factors. Three basic criteria are the same material cost, ease of machining and surface finish. To decide on the choice of material can contribute a few other characteristics of a particular material. Overground factor is also our experience with a particular material, which material often determines who opted for. Finally habit is second nature.
So what materials we have available. Before that I go I check that there are no limits and you can choose almost any material, even one that we have at hand, or one that will be most suitable for a specific honey comb application. Thus, the list of materials that present here does not exhaust all the possibilities, it is only a compendium of information about the most popular. In any case, we should approach the subject individually.
The first decision honey comb we should take before you choose the material, this is what we will be serving this model. Is only for the implementation of manufacturing molds, can be a model to test whether this will be the first copy of the prototype, and perhaps for all time. An important factor is also the size of the model and the accuracy of its implementation. Knowing this, we will be much easier to choose the most suitable material for our purposes. honey comb
One of the most popular materials are polystyrene, styrodur, polyurethane foam, epoxy paste, MDF and aluminum. These materials provide honey comb a full range of parameters. Analyzing their properties will take into account the following honey comb criteria: ease of processing, and hence the processing time, the consistency of the material, keeping dimension, material cost, achieved surfaces, ease of finish, tolerances, surface, weight and other characteristics of a particular material.
Cheapest and easiest Styrofoam workable material. Used for large-scale models, where it is not required honey comb high precision and grip size. Smooth surface, but with the seasons. More difficult in the derivation of the finished surface, because you have to apply the epoxy resins containing no solvents, melting the material. Absorbs water.
Styrodur It is to some extent improved polystyrene, because extruded. It is more consistent honey comb and homogeneous, making a stiffer and more stable. About four times heavier and more expensive than polystyrene. It does not absorb water, so it is suitable honey comb for the prototype model, which will be used on water.
Polyurethane foam disparate material has pores. Workable. Besides the fact that it does not melt polyester resins, it can be compared to a polystyrene or styroduru in terms of parameters. There are foam of different densities, and hence a slightly different parameters, so we can choose the most suitable for our needs.
Epoxy is a very homogeneous material, easily honey comb workable, perfect for smaller honey comb models. Unfortunately, in comparison with other material is more expensive, but it is well done after finishing is achieved almost complete model, which can be painted immediately. It is a mixture of epoxy resin and glass micro-balloons. Pasta is light, honey comb consistent, and you can even carve it by hand.
MDF One of the most popular materials because of the price and the resulting hardness of the surface. Relatively easily treatable. The area treated must be primed, sanded and only suitable for varnishing. Models can swell in a humid environment.
Very cool site, lots of technical advice. I miss only in "model, hoof - what material do" information on how to finish the model, such as polystyrene, styrodur high gloss and these materials cover what luted and paint to get the finished product (read model) to impose distributor and gelcoat . Is the painting is recommended polishing, etc. I have a big request for such information. Regards Maciek
Hello and I am very pleased that the site is like. What Styrofoam honey comb / styroduru it must be cured epoxy (do yourself a sample on another piece - some epoxies are diluted, so melt polystyrene) preferably with some glass tissue (gr. 30g/m2), then wyszpachlować (a good idea to spray polyester honey comb putty) , sanded to the desired surface finish and varnish. It is also sanded and varnished paper aquatic antics przepolerować to shine. It only remains to impose the distributor, and you can build a form. Regards, Maciek
What filler is best to use? and most importantly what paint? Once polakierowałem and, unfortunately, some reaction was and I split a model of the form, although the model has been greased distributor as the book says, luckily it was a small mold for rc model, but since then I somehow gone on making molds. I greet M
