J – CAD Inc. has been assisting clients turn their ideas into reality for over 10 years! Our 3D CAD design experts will help you create your mechanical CAD files required for prototyping. Once your design has been finalized we can also make prototype in house and ship to your door globally. Typical turn around time of design & prototyping is less than a week.

Prototyping is the process of turning an idea into reality. It starts with the creation of a 3D model of the prototype design as requested by an inventor, company or person. The design process may go back and forth a few times before the inventor is satisfied with the 3D model CAD design. Once the design is finalized, fabrication drawings with dimensions of all pieces are created by the CAD designer. With these drawings, the inventor can contact manufacturing companies and give them these drawings to quote the cost of making the first prototype for testing. During the prototype & testing phase of a design, sometimes it is required to make many versions and the design can change many times before a final prototype design is chosen and approved. Only through prototyping & testing can a design be perfected. Once the prototype phase is complete, the inventor can go into mass production and start manufacturing parts on a large scale.

Why is 3d prototyping important?

Prototyping allows for testing and refining a design’s functionality

Your idea could work well theoretically but the design could contain numerous flaws in real life. Prototyping & testing a design gives you the opportunity to realize the flaws and optimize the functionality of you product before going to mass production.


Prototype development enables you to test the performance of different materials

Through prototyping you are able to test the performance of numerous materials to find out which one works best with your prototype design. It will also help you establish the combination of products that is cost effective and efficient for your product.

Prototype manufacturing enables you to understand your product better

After prototyping & testing your product, you will better understand the functionality of your product and how best it can be optimized. Then you can apply this to final design and know that your design is perfect!

As an example of our prototyping work, recently we were commissioned to design a device to change the way eggs are shipped across the USA!

J – CAD Inc. was contacted by EPI Food Safety LLC. to help them design a series of layers that will ship eggs in a totally new very efficient way!

Rapid Prototyping and Development

From Idea To Working Prototype In One Week

Pursuing a great idea doesn’t have to be difficult. With over a decade of experience, J-CAD Inc. has helped transform great ideas from around the globe into innovative tools and lucrative products through our design and rapid prototyping services.

Inventors Don’t Build Without Modeling First

Chances are that your product idea is different from anything that has ever existed before. Through our rapid prototyping and development services, you can:

  • Have professional blueprints, renderings and 3D models in hand within days of your idea
  • Beat the competition to market and roll out your product before anyone else

Smart prototyping can help you achieve your product innovation goals. Unlike product development where products must be produced by the hundreds or even thousands, additive manufacturing (otherwise known as 3D printing) uses cost effective digital CAD models to create physical real-life objects.

Additive processes can be used to create a number of different parts, including:

  • Production parts
  • Tooling patterns & components
  • Functional models
  • Fit and assembly testing
  • Concept models & designs
  • Visual aids
  • Patterns for casting
  • Jigs & fixtures

Best of all, when you work with J-CAD Inc., you can have your prototype in hand within one week of when you make that first call to receive your free customized quote!

Your Material Options and Costs for Prototypes

There are several material options available for your prototype today, including a variety of metals, ceramics, PolyJet photopolymers, FDM thermoplastics, nylons, and other plastics. Electronic components can also be added to any prototype design!

Another reason why 3D prototyping has risen so rapidly in popularity is because it’s a cost-effective way for inventors of any budget to turn an idea into a reality. Here are a few of the costs you may encounter throughout the development process:

  • Hourly designer rates
  • Product costs
  • Assembly costs
  • Electronic component costs

Wondering how much your project may cost? Give us a shout! J-CAD Inc. will review your information and send you a customized quote within 24 hours, with design and 3D printing costs.

Different Prototyping Processes for Different Jobs

J-CAD Inc. offers a number of different prototyping methods, each of which serve different purposes. For example, let’s say you’re an engineer who has a product idea involving moving parts. Your designer may start off with a series of 3D CAD models since these allow for the quick creation and virtual assembly of components.

When you’re ready for your first physical prototype, you may design your idea through BJET or your designer may produce additive prototypes from those CAD models (like an SL prototype for the shell of your product and SLS prototypes for your product’s internal components). If your prototype is ready for functional testing, you might need to choose one or more other processes for optimal results.

Choosing the Right 3D Prototyping Process

While there isn’t one additive prototyping process that is better than the next, one prototyping method may be more suitable depending on which phase your project is in.

SL (Stereolithography)

SL harnesses the power of a computer-controlled laser to construct parts within a pool of UV-curable resin. As the laser draws each layer, the part is gradually lowered into the liquid resin, allowing the next layer of liquid to be strengthened and solidified.

Benefits: This is a moderately priced option that offers a superior surface finish and that can easily duplicate complex geometries.

Drawbacks: SL is low in strength and limited to being useful only for functional testing.

SLS (Selective laser sintering)

Through SLS, a CO2 laser controlled by a computer fuses layers of powdered material (like nylon) from the bottom all the way to the top.

Benefits: SLS is cost effective and stronger than SL. It can be used with a range of materials, offers great accuracy of form and size, and it easily duplicates complex geometries.

Drawbacks: There is a limited choice of resins for SLS and it produces a rough surface finish.

BJET (Binder jetting)

Known as being among the simplest and most basic of the 3D prototyping processes, binder jetting uses an inject print head which selectively deposits liquid binding material across a bed of powder. This process is repeated over and over again until the part has been formed.

Benefits: It’s fast, cheap, and duplicates easily.

Drawbacks: Products aren’t strong and it’s not a suitable option for functional testing.

FDM (Fused Deposition Modeling)

This process melts and re-solidifies thermoplastic resin (like polycarbonate, ABS or a combination of the two) in multiple layers to produce a finished prototype.

Benefits: Though more expensive than BJET, it’s still inexpensive, offers greater strength, and it duplicates complex geometries well.

Drawbacks: FDM is not always suitable for functional testing and it can take days to produce larger parts. It also leaves a rippled surface and it is not strong on the z axis.

PJET (Polyjet)

A printhead sprays layers of a photopolymer resin that are cured one by one using UV light. The material receives support from the gel matrix that’s removed after the part is completed.

Benefits: Moderately priced, elastometric parts can be prototyped with PJET. There are several color options out there and it can easily duplicate complex geometries.

Drawbacks: PJET prototypes have limited strength and colors can gradually take on a yellow hue if exposed to light over a period of time.

DLP (Digital Light Processing)

This process uses digital processes to slice a solid piece of material into layers upon a surface of a liquid photopolymer bath which is resting on a movable build plate. Light projected onto the surface hardens the layer of liquid polymer and the build plate moves in increments as new images are projected onto the liquid. Each subsequent layer hardens to produce your finished object.

Benefits: Arguably most useful for producing low volumes of smaller and highly detailed parts, DLP is fairly fast and can produce complex shapes.

Drawbacks: Prototypes made through DLP lack strength and aren’t suitable for functional testing. The materials are also costly and there is a limited choice in resin available.

DMLS (Direct Metal Laser Sintering)

DMLS is the top choice for those who are interested in crafting metal prototypes. Similar to the SLS of plastic resin, this method is suitable for a variety of alloys including:

  • Stainless steel
  • Aluminum
  • Cobalt chrome
  • Titanium
  • Inconel

This process can be used for the smallest of parts and the most detailed of features, and it can reproduce geometries which may otherwise be impossible to machine because it is an additive process.

Benefits: Layers can be as thin as 20 microns and features can be as tiny as ±0.002 inches. This method can be used with almost any alloy and the mechanical properties of the parts produced are equal to those of conventionally formed parts.

Drawbacks: DMLS is expensive and is the slowest of the additive processes.
