The objective of this information is to offer an outline on techniques that can be used to InventHelp Inventor Stories an invention and make a small volume creation run. This information will not cover the methods in depth. You will find several resources available on the internet for each of the techniques pointed out in the post. Quite this short article will show the best way to combine the techniques to produce a prototype and multiple copies. By making use of these techniques or variations, an inventor or entrepreneur would be able to create a prototype and several copies. Additionally, using the methods I layed out in a previous article I wrote on low costs product packaging and inventor or businessperson can produce a relatively total item that may be test marketed or shown to a possible licensee.


First some warnings concerning the techniques layed out listed below. These are rather work intensive. Not hard actual physical work by itself, nevertheless it does require understanding and developing additional skills. Further, the quantity of copies that can be made utilizing silicone molds differs and is centered on the geometry of the components being shaped. Often the life time of a silicone mold is different from as couple of as 25 duplicates to a few hundred. An additional factor is how much treatment is consumed in extracting the components. The rougher the mold is taken care of the smaller its lifestyle.

In addition, these methods usually are not practical for producing elaborate prototypes including complicated mechanical devices. These methods are definitely more fitted to creating prototypes composed of some components (1 to 3) with either a single element or in which several elements are fixed together.

Lastly care should be consumed in selection of suitable casting material. Be sure to use components which are safe for your prototypes application. Tend not to use harmful components particularly in any prototype to be utilized within the handling of food or by kids.

Making the Prototype Design

The pattern will be the preliminary prototype and will be utilized to create the molds to produce copies. The strategies that can be employed to make a preliminary prototype consist of but are not limited to those outlined listed below. Use any technique which will yield a usable pattern. Please do not really feel confined to this listing of techniques. Feel free to be as innovative in finding a method to have the design when you had been in coming up with the concept.


A good way to make a prototype design would be to shape the form in wax tart, clay-based or some other appropriate sculpting materials. The issue with wax or clay is because they are either fragile (wax) or deformable (clay-based). Some clay-based can be fired, heated up, so that they are no longer deformable. However brittleness is still a problem. There some sculpting materials including Magic-Sculpt (available at Tap Plastic materials) that stays pliable for a few hrs and then cures to rock hardness. In order to generate the desired shape sculpting resources are often needed. Resources for these particular resources can be found on the Internet.


Another method nearly the same as sculpting is carving. A Product Ideas might be whittled out of timber for instance. If however the fabric is permeable, the top will need to be sealed employing a appropriate surface area therapy for instance a sealer or primer. To make the carving work simpler an electrically powered rotary tool can be utilized. Similar to sculpting, sources for the tools and techniques related to carving can be found on the Internet.

Rapid Prototyping

Generally to use a rapid prototyping method a pc Assisted Style (CAD) 3 dimensional model is needed. This design is exported to a appropriate file format such as a stereolithographic file. The file is then read by a personal computer automatic device that makes the part. The processes are either additive or subtractive. In an ingredient process materials is additional by solidifying or fusing material. A personal computer managed laser may solidify a fluid by way of a photochemical procedure or adherence of solid materials by sintering or fusing. The part’s position is also personal computer controlled. These procedures are called by a number of names like SLA (stereolithography), SLS (selective laser beam sintering) and FDM (merged deposition modeling). More details can be found on the following website

An illustration of this a subtractive process is personal computer numerical managed machine tooling (CNC). In this case your computer managed machine device removes material to create the parts.

There are numerous businesses offering prototyping solutions. Actually, many SLA companies have Internet sites in which the CAD model can be uploaded, a cost quoted, components ordered and bought through a credit card payment. The process is nearly completely automatic. Nevertheless, there is a check done on the uploaded file to verify the intentions in the consumer. Occasionally you can find problems with the file. On the other hand, the CNC procedure has a a lot lower degree of automation. A program needs to be written for your component model and stock material has to be packed into the machine. This program may be generated by software but as before a check must confirm motives and fidelity in the file.

Silicone Molds

After a prototype pattern is finished a silicone mold can be made utilizing space temperature vulcanization (RTV) procedure. Most of the RTV materials are non toxic and are simple to use. Further silicone molds can take temperatures as much as around 500 levels Fahrenheit and can be use to cast reduced heat casting precious metals such as pewter. As there are numerous sources on the Internet that provide instruction on the method it does not be covered right here. Materials for RTV molding can be found on the Web and thru Tap Plastic materials. However the following pointers are available. First use gloves not just to maintain the types of materials away your hands but also to keep finger prints off of the prototype pattern. The molding material is able to produce extremely fine surface area detail. In case a finger print out had been on the pattern it could pick it up plus it would show up on all your duplicates. Second, the fabric is extremely fluid so make sure your mold frames are well sealed. Furthermore, pay attention to the parting outlines of your mold – where the mold comes apart to eliminate the casting. Ensure you can find no places that the silicon rubberized can stream to capture the part. For instance, the handle of the mug would need that the mold would component on a plane via the middle of the mug and parallel for the handle. There will be handle perceptions on both edges of the parted mold displaying a user profile of the cup and handle.

Depending on the prototype pattern it may be possible to create a a single item mold which is totally open on one part. This sort of mold is normally used for reduced heat casting precious metals. To get a two item mold be sure and utilize mold release on the first component before throwing the second. If this stage is overlooked the foremost and second halves will fuse with each other and tarp the prototype design. Also for your two part mold make sure to not overlook to set the spews and a fill dock. Spews are air vents that permit stuck gases to flee and also the mold is filled up until the resin runs away from them. If the casting is set and the mold is parted the spews and the fill port will leave a column that has to be stop. Therefore be sure to place them in which you can easily touch up the surface. The spews will need to go on the highest portion of the design so that air is not kept in the mold. Spews and the inlet can be produced by adhering rods vertically on to the prototype pattern and hold them in place using a supporting structure linked to the mold framework. Within an adhesive can be used make certain that it will not interfere with the curing in the silicon molding material.

Use mold release liberally on the appropriate surfaces of the How To Patent An Invention and all sorts of surfaces of the spews and fill up port. This is important to ensure that the castings can be eliminated and also to extend the life span from the mold.

To prevent the development of bubbles on the surface of the prototype pattern, color the top being shaped with the molding material. To maintain bubbles from forming in the body from the mold, put the silicone substance gradually and attempt to slim out the molding substance within the lip of the pouring container to burst open bubbles currently inside the material. It is very difficult not qupxip introduce bubbles while mixing. Usually a vacuum degassing holding chamber is utilized to get rid of the bubbles. Nevertheless, with plenty of care the bubbles should not be a problem for many prototype designs.

Finally to get a complicated 3 measurement casting think about a bottom up approach. Which is, secure the prototype pattern making use of the top of the molding frame and fill the frame approximately its surface. The design has to be safely held in place or it may drift. Similar to the spews and fill up spout make sure that no matter what assisting structure is put in place will not irreparably mar the surface of the throwing.
