If your company has decided to buy a 3D printer so you can create your own scale models, you need to study your options carefully before you make the actual purchase. That is because 3D printers are not exactly inexpensive, with entry level units costing around US,000. Not all companies have that much capital to spare on machines like that and buying machines that you will end up not using is only a waste of resources.

So that you will not end up with a machine that will eventually just gather dust in your storage room, you need to weigh in a few considerations before you buy your 3D printer. Here are six tips that can guide you along the way.

1. Identify your needs. Before you buy the 3D printer, ask yourself why you need the machine in the first place. What are you going to use it for? Will you be using it to test and validate the designs you have drafted? In that case, you will need a 3D printer that is not fussy so long as it comes up with the models that you need. Will you be presenting your scale models to your clients?

2. Assess your needs. As useful as a 3D printer may be to your company, if you do not create more than a couple of scale models in a month, it may be more cost-effective for you simply to outsource your scale models to a service provider. After all, the costs of a 3D printer do not just involve its purchase price but also the price of the resins and powder you will use with the printer as well as maintenance and tune-up done at least once a year.

3. Consider if the machine will indeed meet your needs. If you have determined that your company will really benefit from having a 3D printer at your disposal, you may want to consider a number of 3D printer models and take a good look at their features. Not all prototyping machines are made with the same features, so you would want the kind that will suit your needs the most.

4. Weigh in the sensitivity of your projects. One advantage of having your own 3D printer is that you may be bound by a confidentiality clause with your project contracts. Outsourcing your models can jeopardize that confidentiality clause, even if your service provider signs a non-disclosure agreement.

5. Ask for a demonstration. You can also ask the dealer from which you will buy your 3D printer for a demonstration of how the printer works from start to finish. This demonstration can give you a clear idea of how the machine will serve your needs, especially if the dealer allows you to operate the sample machine on your own.

6. Inquire about after-sales support. Since 3D printers can be sensitive machines, you will need some after-sales customer care from the dealer or the manufacturer. Do not hesitate to inquire what kind of product support they provide before you buy. Also, ask about the costs of maintaining the machine and the costs of the materials to be used with the printer.

This video documents our Daft Punk Helmet build from start to finish. The plastic parts were modeled in SolidWorks and then printed on 3 3D printers. The visor was vacuum formed in my kitchen over a CNC machined mold. We used express PCB to build the circuit boards and are running a PIC 16F on each half of the helmet. All the circuitry is contained in each “light assembly” thanks to the use of surface mount components. Check out uiproductions.blogspot.com for build details. No helmets are for sale. And a special thanks to Volpin for inspiring us to do this.

If you take a look at the history of mankind you will see precisely how adventurous, restless, forward reaching as well as creative we have been. From the particular period when man conceived the wheel up to the modern-day when there seems to be no limit to our inventive capability, we’re all proof of our need to reach for the heavens.

Not many of us like to sit around and do nothing at all. We always have to focus on a mission and this is what pushes a lot of us to build our very own companies and to create a much better future for ourselves. There’s nothing that can match the sensation of total satisfaction after you build something from nothing and dissatisfaction frequently spurs us to move on to even bigger and far better things.

From a time when all of us were really young there was a fascination for modelling as well as for scale models of everything that we might observe in the grown-ups’ environment. Just how many of us enjoyed playing with model railways and definitely with toy cars, at some point dreaming about owning a full-sized edition? Frequently, we might take hours playing with a Lego set and creating the most outrageous kits. To this day, a lot of us are intrigued by these types of blocks and this once again underlines the fact that we are constantly looking for something fresh as well as completely new.

These days, as we grow we could elect to follow a career in architecture, engineering or perhaps the technological career fields and begin to genuinely explore exactly how to create something from nothing in breathtaking fashion. We could furthermore decide to turn our innovative bent towards making models in our extra time.

Whatever reason you might have for building something out of thin air, you should source some model making materials and also model making supplies that will help you stick to your inventive path. While you may well sketch something out on paper, two-dimensional seriously isn’t likely to work for you personally. You must view a three-dimensional rendition of your work and will want to embark on the creation of a scale model.

Scale models are produced in a variety of spheres. You possibly can be commissioned within an engineering challenge, or whenever a new building construction is being designed. The model could be made for a feature film and it might also be used to demonstrate to would-be purchasers exactly how a special housing development may appear in the future – a very important sales resource.

Even if you just want to create a model for your own excitement, you’ll need a number of model making tools and also supplies. A lot of these can be as sophisticated and also as involved as the model that you’re planning. You will require such items as drills, saws, rotor blades, scissors, tweezers, pliers and the types of materials by themselves. You will likely need board, sheet, aluminium, polystyrene, wood, foam board, PVC material, tubing, angles, rods and fasteners. When you discover what can be acquired and let your imagination start to percolate, there truly is very little to stop you from developing your very own, fresh new world.

I know nothing about 3D design, but just interested in the approx design time. Assuming that 5-10 3D modelers/engineers were working on it and it would eventually be built and flown. However, it’d use a lot less parts and most likely different materials than the original aircraft. The original has like 24,000 or so parts but this would be cut in half.
