CNC machined prototype

The prototype in CNC is produced in a numerical control machine, requiring a competent team of programmers for preparing the part machined in several materials.

​For complex parts, which require control and precision in the machining process, Fastparts makes available an automated system of zeroing with Renishaw process which provides flexibilization and maximization of the results of the machining, increasing the efficiency and productivity of the machining.

Besides materials as PU foam and MDF for conceptual models, metallic parts, ABS and Nylon, Fastparts is a specialist in the area of materials as acrylic, which require skill and mastery in the finishing.

Fastparts maintains the equipment always updated to offer quick and high quality solutions in the prototyping market

Normal Scale Prototype

In the process of developing products, it is necessary to develop the prototype of the part in question, so that it is possible to check and validate the project details.

Besides the human resources, Fastparts offers the technology required to ensure total safety ion the previews of the validations. They are as follows:

  • Quick prototyping technology
  • Numerical command machine
  • Digitization and finishing with painting

The prototypes undergo a series of strict quality processes, being validated by the dimensional control process with images of the products digitized in 3D.

Serial Prototype

To execute the production of prototypes in scale it is necessary to have expertise in the processes and technologies used. Fastparts offers several types of reproduction process.

Prototypes in Plates

The development of prototypes in plate requires the use of simplified stamp tools, where the geometry of the part is ensured by the machining processes and cuts and their details are defined by the laser equipment.

The finishing can be galvanized, anodized or total paint as per project details.


  • Low cost
  • Flexibility of alteration of the tool
  • Stamped in the material supplied by the customer
  • Stamp with injection developed by Fastparts
  • Average term of 10 to 30 days, depending upon the geometrical complexity of the part

Mock ups

One of the main challenges in conceiving a project is the need to know volumes, shapes, ergonomics, agreements and several other details which, in CAD 3D, are difficult to perceive.

Thanks to the technological and human resources used by Fastparts, the preparation of the Mock-ups, executed in materials as Polyurethane foam, MDF, high density  Polyurethane plates together with the paint finishing and details, has all the details checked with great care, ensuring the complete fulfillment of the project requirements.


  • Implementation of simulating details, LEDs, textures and colors;
  • Projects which can be used in market evaluation clinics;
  • Quick perception of approval of concept and styles;
  • Integrating processes as machined prototype, quick prototype; 

Painting Finishing

The challenges of having the models and prototypes with end product finishing if one of the specialties of Fastparts. Transparent parts machined in acrylic can receive pigmentation giving coloring to the product.

Purposes of painted models and Prototypes:

  • Special events as a trade fair
  • Market evaluation and clinic
  • Validation of Design

Fiberglass Lamination

With CNC resources and specialized labor, this process allows models to be prepared in the most varied shapes in materials as PU foam, MDF or resin.

Fiberglass reinforcement layers are applied in the models, interspersed with blankets and tissues impregnated with Polyester, Vinyl Ester or Epoxy resins, until the prototype takes its end form.

​Hand lay-up until the ideal thickness is attained, this process being widely used in the automotive industry in usability tests.


  • Special projects for events;
  • Automotive parts which require run tests;
  • Marking of vehicles which are prototypes;
  • Nautical parts;
  • Decorative parts;
  • Aeromodeling.

Vacuum Forming

Thermoforming is indicated for reproducing prototyped parts which allow small thickness  variances.

It is widely used in prototyping refrigerator door panels, covers and drawers, having as main feature the use of the final material, thereby ensuring that they undergo rigorous field and laboratory tests.


  • Speed ​​of execution;
  • Low cost;
  • High degree of complexity of the project;
  • Excellent finish;

Reverse Engineering

With the technology of the Fastparts one can do the inspection of already manufactured prototypes and or the reverse engineering. It is suitable for quality control of small and medium pieces of plastic or metal and its non-contact measuring principle allows the measurement of fine and fragile objects, which in conventional measuring machines are difficult, in addition to the generated nurbs these serve reference for modeling more easily and geometrically. With a qualified and trained team, Fastparts elaborates the 3D models and from this model elaborates the prototype for validation.

With the inspection software, a dimensional analysis of a data set is carried out that allows to extract information for applications such as the correction of shapes, location of points of wear and areas that need to be reconditioned.

Device Control

The prototypes that need to be controlled and measured go through the engineering of Fastparts for the elaboration of control device. These devices serve for the validation of the series of prototypes.

The devices are made by Renshape resin or aluminum depending on the complexity of the design.
