Mechanical Quick Turn Rapid Proto Typing

In General a rapid prototyping machine using Selective laser sintering.

eBonsella will provide rapid prototyping is the automatic construction of physical objects using solid freeform fabrication. The first techniques for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts. Today, they are used for a much wider range of applications and are even used to manufacture production quality parts in relatively small numbers. Some sculptors use the technology to produce complex shapes for fine arts exhibitions.


Rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software, transforms them into thin horizontal cross sections, still virtual, and then creates each cross section in physical space, one after the next until the model is finished. It is a WYSIWYG process where the virtual model and the physical model correspond almost identically.

With additive fabrication, the machine reads in data from a CAD drawing and lays down successive layers of liquid, powder, or sheet material, and in this way builds up the model from a series of cross sections. These layers, which correspond to the virtual cross section from the CAD model, are joined together or fused automatically to create the final shape. The primary advantage to additive fabrication is its ability to create almost any shape or geometric feature.

The standard data interface between CAD software and the machines is the STL file format. An STL file approximates the shape of a part or assembly using triangular facets. Tiny facets produce a higher quality surface.

The word "rapid" is relative: construction of a model with contemporary methods can take from several hours to several days, depending on the method used and the size and complexity of the model. Additive systems for rapid prototyping can typically produce models in a few hours, although it can vary widely depending on the type of machine being used and the size and number of models being produced simultaneously.

Some solid freeform fabrication techniques use two materials in the course of constructing parts. The first material is the part material and the second is the support material (to support overhanging features during construction). The support material is later removed by heat or dissolved away with a solvent or water.

Traditional injection molding can be less expensive for manufacturing plastic products in high quantities, but additive fabrication can be faster and less expensive when producing relatively small quantities of parts.


A large number of competing technologies are available in the marketplace. As all are additive technologies, their main differences are found in the way layers are built to create parts. Some are melting or softening material to produce the layers (SLS, FDM) where others are laying liquid materials thermosets that are cured with different technologies (SLA, MJM, PolyJet). In the case of lamination systems, thin layers are cut to shape and joined together.

Molding Machining Sheet metal :

Injection molding

Is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity.[1] After a product is designed, usually by an industrial designer or an engineer, molds are made by a mold maker (or toolmaker) from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.

Examples of polymers best suited for the process

Most polymers, sometimes referred to as resins, may be used, including all thermoplastics, some thermosets, and some elastomers.[6] In 1995 there were approximately 18,000 different materials available for injection molding and that number was increasing at an average rate of 750 per year. The available materials are alloys or blends of previously developed materials meaning that product designers can choose from a vast selection of materials, one that has exactly the right properties. Materials are chosen based on the strength and function required for the final part, but also each material has different parameters for molding that must be taken into account.[7] Common polymers like epoxy and phenolic are examples of thermosetting plastics while nylon, polyethylene, and polystyrene are thermoplastic.[8] Until comparatively recently, plastic springs were not possible, but advances in polymer properties make them quite practical. Among such applications are buckles for anchoring and disconnecting outdoor-equipment webbing

Metal injection molding (MIM) is a metalworking process where finely-powdered metal is mixed with a measured amount of binder material to comprise a 'feedstock' capable of being handled by plastic processing equipment through a process known as injection mold forming. The molding process allows complex parts to be shaped in a single operation and in high volume. End products are commonly component items used in various industries and applications

Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.

Liquid silicone rubber is a high purity platinum cured silicone with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is a must. Due to the thermosetting nature of the material, liquid silicone injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.

Chemically, silicone rubber is a family of thermoset elastomers that have a backbone of alternating silicon and oxygen atoms and methyl or vinyl side groups. Silicone rubbers constitute about 30% of the silicone family, making them the largest group of that family. Silicone rubbers maintain their mechanical properties over a wide range of temperatures and the presence of methyl-groups in silicone rubbers makes these materials extremely hydrophobic.

Typical applications for liquid silicone rubber are products that require high precision such as seals, sealing membranes, electric connectors, multi-pin connectors, infant products where smooth surfaces are desired, such as bottle nipples, medical applications as well as kitchen goods such as baking pans, spatulas, etc. Often, silicone rubber is over molded onto other parts made of different plastics. For example, a silicone button face might be over molded onto an Nylon 6,6 housing.

Plastic can cover many synthetic or semi synthetic polymerization products. This applies to Plastics the World Over from Here on the West Coast of the United States , Nationally or In Asia or Europe .They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity.

    Common plastics and their uses:

    Polyethylene (PE)
  • Wide range of inexpensive uses including supermarket bags, plastic bottles.

  • Polypropylene (PP)
  • Food containers, appliances, car fenders (bumpers).

  • Polystyrene (PS)
  • Packaging foam, food containers, disposable cups, plates, cutlery, CD and cassette boxes.

  • High impact polystyrene (HIPS)
  • Fridge liners, food packaging, vending cups.

  • Acrylonitrile butadiene styrene (ABS)

  • Electronic equipment cases (e.g., computer monitors, printers, keyboards).

  • Poly(ethylene terephthalate) (PET)
  • Carbonated drinks bottles, jars, plastic film, microwavable packaging.

  • Polyester (PES)
  • Fibers, textiles.

  • Polyamides (PA) (Nylons)
  • Fibers, toothbrush bristles, fishing line, under-the-hood car engine moldings.

  • Poly(vinyl chloride) (PVC)
  • Plumbing pipes and guttering, shower curtains, window frames, flooring, erotic clothing.

  • Polyurethanes (PU)
  • Cushioning foams, thermal insulation foams, surface coatings, printing rollers. (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic found in cars).

  • Polycarbonate (PC)
  • Compact discs, eyeglasses, riot shields, security windows, traffic lights, lenses.

  • Polyvinylidene chloride (PVDC) (Saran)
  • Food packaging.

  • Bayblend (PC/ABS)
  • A blend of PC and ABS that creates a stronger plastic: Car Interior and exterior parts.

    Special-purpose plastics:

    Polymethyl methacrylate (PMMA)
  • Contact lenses, glazing (best known in this form by its various trade names around the world, e.g. "Perspex", "Oroglas", "Plexiglas"), fluorescent light diffusers, rear light covers for vehicles.

  • Polytetrafluoroethylene (PTFE) (trade name Teflon)
  • Heat-resistant, low-friction coatings, used in things like "non-stick" surfaces for frying pans, plumber's tape and water slides.

  • Polyetheretherketone (PEEK) (Polyketone)
  • Strong, chemical- and heat-resistant thermoplastic, biocompatibility allows for use in medical implant applications, aerospace moldings. One of the most expensive commercial polymers.

  • Polyetherimide (PEI) (Ultem)
  • A General Electric product, similar to PEEK.

  • Phenolics (PF) or (phenol formaldehydes)
  • High modulus, relatively heat resistant, and excellent fire resistant polymer. Used for insulating parts in electrical fixtures, paper laminated products (e.g. "Formica"), thermally insulation foams. It is a thermosetting plastic, with the familiar trade name "Bakelite", that can be molded by heat and pressure when mixed with a filler-like wood flour or can be cast in its unfilled liquid form or cast as foam, e.g. "Oasis". Problems include the probability of moldings naturally being dark colors (red, green, brown), and as thermoset difficult to recycle.
  • Urea-formaldehyde (UF), one of the aminoplasts and used as multi-colorable alternative to Phenolics. Used as a wood adhesive (for plywood, chipboard, hardboard) and electrical switch housings. Melamine formaldehyde (MF), one of the aminoplasts, and used a multi-colorable alternative to phenolics, for instance in moldings (e.g. break-resistance alternatives to ceramic cups, plates and bowls for children) and the decorated top surface layer of the paper laminates (e.g. "Formica").

  • Polylactic acid
  • A biodegradable, thermoplastic, found converted into a variety of aliphatic polyesters derived from lactic acid which in turn can be made by fermentation of various agricultural products such as corn starch, once made from dairy products.
  • Plastarch Material
  • Biodegradable and heat resistant, thermoplastic composed of modified corn starch.

Sheet Metal & Machining:

Most machining operations here on the West Coast of the United States and or Overseas can be divided into those that remove metal from an item, and those that form metal in an item.

Often an unfinished work piece will need to have some parts removed or scraped away in order to create a finished product. For example, a lathe is a machine tool that generates circular sections by rotating a metal work piece, so that a cutting tool can peel metal off, creating a smooth, round surface. A drill or punch press can be used to remove metal in the shape of a hole. Other tools that may be used for various types of metal removal are milling machines, saws, and grinding tools. Many of these same techniques are used in woodworking.

Metal can be formed into a desired shape much more easily than materials such as wood or stone, especially when the metal is heated. A machinist may use a forging machine to hammer or mold a hot metal work piece into a desired shape. Dies or molds may be used if the metal is soft enough, or under high pressures. A press is used to flatten a piece of metal into a desired shape.

Shape modifying with material retention processes

    These processes modify the shape of the object being formed, without removing any material.
