The E-make team has more than 30 years of combined experience in building prototypes. We have worked with a broad range of companies in the past, ranging from young startups, design houses to large contract manufacturers. Through providing professional guidance in mechanical design and high quality looks-like prototypes, we have helped our clients impress their customers or investors, leading to successful sales campaigns that raise hundreds of thousands of dollars or large seed round investments.

At E-make, our engineers use advanced equipment and techniques like 3D printing, multi-axis CNC machining and rapid tooling to turn your designs into reality quickly, accurately and at a great price (often as low as 50% of the price one would pay in Europe or North America). You design it and we will make it.

We are located in Shenzhen, China, in a facility of over 1500 square meters. If you are in town and would like to visit or have a prototype to make, please do not hesitate to reach out to us. Do not worry about any language barriers, our salespeople can communicate in both written and verbal English and they will ensure that the engineering team pays attention to every last detail in the CAD drawings.


Rapid Prototyping

Rapid Prototyping is often used to produce a physical sample of a design concept. It can be used to evaluate form, fit and function and to test out new and innovative ideas. Prototypes are often made of less robust, and therefore less expensive, materials. And “rapid” is critical to many of our clients because they need to produce a physical part quickly in order to validate a design or to capture a fleeting sales opportunity.

Contact us if you require any rapid prototyping services.

Benefits of prototypes

Show your customers and investors a model of your product

Demonstrate the appearance, dimensions and features of your product

Test your design for its suitability

Save time and money by identifying and reducing design flaws

Improve and streamline the production process

Reduce your work load when the time comes to manufacture

Create multiple versions with different colors, surface textures, etc.

Our one stop shop prototyping services include: CNC machining, SLA/SLS 3D printing and rapid tooling.

CNC machining


CNC machining works well for smaller quantities of up to 100+ parts. We use milling and turning to machine engineering-grade plastic and metal parts for prototyping and production. Get machined parts for functional testing, cylindrical applications, jigs and fixtures, and any one-off needs.

Take a look at our past CNC projects.

Advantages of CNC machining

Quick removal of large amounts of material

Highly accurate and repeatable

Suitable for many different kinds of substrates

Scalable volumes from one to one-hundred thousand

Low investment in tooling or preparation costs


Fast turnaround



SLA (stereolithography) is the first of the additive manufacturing processes collectively known as “3D printing”. A special type of liquid plastic is used that reacts with ultraviolet (UV) light to form a solid. An object is created by slowly curing one layer at a time using a programmable UV light source.

SLS (stereo laser sintering) is also a method for making rapid plastic prototypes, but in this case the raw material is a fine powder. A programmed laser is used to fuse the powder into a solid one layer at a time to create the finished product. Objects are created on a build platform, which is carefully controlled by a computer to move down the thickness of one layer with each successive addition of powder.

Take a look at our past SLA/SLS projects.


We offer both SLA and SLS prototyping to create solid physical models in Resin, ABS, nylon, and other grades of engineering plastic.


SLA and SLS models typically have layer thicknesses of .3mm with a lateral deviation of .1mm. Finer tolerances than this can easily be achieved with post machining per customer requirements.

SLA Properties

Good, smooth surface finish and fine resolution

Slow, making it unsuited for high volume production

Inexpensive compared to their conventional counterparts

Layer thicknesses of .3mm with a lateral deviation of .1mm

Easier to create complex pieces that are physically impossible to make with conventional or subtractive manufacturing

SLS Properties

Rough surface finish that requires post-processing

Faster to make than SLA

Stronger than SLA, so they are more suited for functional engineering parts

Inexpensive compared to their conventional counterparts

Layer thicknesses of .3mm with a lateral deviation of .1mm

Easier to create complex pieces that are physically impossible to make with conventional or subtractive manufacturing

vacuum casting


Vacuum casting is a low-cost but reliable method for making a small number of high quality prototypes based on a master model. This method is ideal for rapid prototyping used in engineering testing, proof-of-concept, sales and display demos to name a few with short lead times. The level of detail and surface finish of the copies is dependent on the quality of the master pattern. You choose the casting compound to match your design idea - hard or soft, colored or clear. We even offer overmolding to combine two or more different types of material in a single finished casting.

Take a look at our past vacuum casting projects.

Advantages of vacuum casting

Low initial cost since it does not require expensive hard tooling

High fidelity of the mold gives excellent surface details requiring little or no post-processing

Many different molding polymers are available that can be pigmented per your color requirements

Molds can be ready in a few days once the master pattern is available

One mold is durable up to approximately 20 copies

Overmolding can be performed, so that different types and hardnesses of plastic can be molded together into a single unit

Reaction injection molding

Reaction injection molding and injection molding have almost the same name, so even experienced engineers and designers might think they are the same. But “Reaction” signals a big difference – unlike injection molding, RIM techniques utilize low-viscosity liquid polymers in thermoset – not thermoplastic – processes. Through a variety of chemical reactions, these polymers expand, thicken and harden only after they’re injected into the heated mold, accommodating much more intricate designs than ordinary injection molding. Raw materials and molding techniques can be selected and even customized to precisely deliver desired weight, strength, density and hardness characteristics. The result is large polyurethane parts with much lighter weight than those created by more commonplace processes.

Low-Volume Manufacturing


Whether you need a hundred parts every few months; or you need hundreds of thousands of parts every month, our low-volume manufacturing service is for you. It’s great if you need small quantities on a regular basis or if you want to bridge the gap between the prototyping stage and full-scale production. Get to market faster with E-Make Prototype’s low-volume manufacturing service.

Benefits of Low-Volume Manufacturing

Many of our customers choose low-volume production to allow for flexibility in customization and design changes, to test the market, and for cost savings. This is especially true if we have already worked with them on creating the initial prototype of a new design idea. With our fast, low-volume manufacturing process, you can have your parts quickly. When you need more we will have your tool on hand ready to go. This will ensure you save time every time.

Low cost

Faster time to market

Design flexibility

Can serve as bridge production
