When designing plastic components, mistakes are repeatedly difficult to avoid. I will give several tips on how to steer clear of mistakes by using rapid prototyping. A technique to spot problems early on is to manufacture rapid prototypes. There are a few methods to make samples. I am going to point out a number of of those processes.

Sticking to good design guidelines and using the newest CAD computer software may help keep away from many design problems. A number of those techniques are thermal and strength analysis, motion analysis and flow analysis as well as analysis of the assembly process of every component as well as subassembly. Rapid prototypes which are a further good method to find problems early on can be produced by employing a number of techniques. Each of these methods offers advantages and disadvantages. Next I will introduce a number of of the most common techniques that are typically used in the contemporary design flow.

The most common procedure is stereolithography (SLA) which uses an UV laser, a vat of photo-curable resin as well as a computer. This procedure works through solidifying the liquid resin by the UV laser. The platform is firstly lowered into the resin so that it sits one layer width underneath the surface of the resin. The laser which is controlled by the computer will then solidify the resin at every point that it touches at this layer. The platform is then lowered an additional layer and the process is continued for each layer until the prototype is finished. Next the prototype is removed from the resin and dried. SLA has characteristic steps because of the layering method that require smoothing of the surface to finish the model.

An additional process that is often less costly than SLA is named machined plastic prototype (MPP) in which a CNC machine is used to shape the replica from a solid block of plastic by cutting away any excess material.  Unlike conventional rapid prototyping processes, the MPP material is a production grade plastic which is durable enough for end-use applications.

Another method, known as selective laser sintering (SLS) works rather similar to SLA. It also utilizes a laser and forms components by sintering a powder-based material. Parts are shaped within a part chamber.  A thin layer of material is sintered by the laser on top of the build platform. The platform subsequently lowers one layer thickness and the leveling roller pushes material from the powder cartridge across the build platform, where the next cross section is sintered to the previous. This goes on until the component is finished.  Next the model is taken from the chamber. Any excess material is removed and the outer surfaces are polished.

An additional layer-by-layer based solid-based prototyping method that uses a build platform, extrusion nozzle and control system is generally known as fused deposition modeling (FDM). In this process, the material is melted and then extruded through a particular head onto the platform for the first layer and then the platform is lowered a layer and the process repeats until all layers of the model are formed.

Whilst designing plastic parts, errors are often tough to avoid. I will offer a few tricks on how to steer clear of mistakes that normally will need costly injection mold rework. Rapid prototypes can help keep away from those errors early on. I am going to describe several of the techniques to manufacture rapid prototypes.

Following good design guidelines and employing the latest CAD software may help avoid a lot of design problems. Some of those methods are thermal and strength analysis, motion analysis and flow analysis as well as analysis of the assembly process of each part and subassembly. One more line of defense against pricey tooling reworking is to build rapid prototypes. Prototypes frequently help detect a big variety of problems early on. Those may be manufactured using a number of techniques. Next I am going to illustrate the most important methods to build prototypes.

The most popular procedure is stereolithography (SLA) which consists of an UV laser, a vat of photo-curable resin along with a computer. This procedure works by solidifying the liquid resin via the UV laser. The platform is firstly lowered into the resin such that it sits a layer width below the surface of the resin. The laser which is controlled by the central processing unit will subsequently solidify the resin at every point which it touches at this layer. The platform is subsequently lowered an additional layer and the process is continued for every layer until the prototype is finished. After that the prototype is removed from the resin and dried. SLA has characteristic steps on account of the layering technique that require smoothing of the surface to finish the replica.

Machined plastic prototypes (MPP) is a subtractive rapid prototyping fabrication technique for producing plastic prototypes.  The plastic material is removed from a solid block by Computer Numerical Control (CNC) equipment that cuts away the surplus material.  One difference of this method in contrast to SLA is that most plastic materials may be utilized. This provides the benefit that the sample will have comparable strength as well as behavior as the finished part.

Another technique is known as selective laser sintering (SLS) which utilizes a laser to sinter a powder-based material layer by layer inside a part chamber.  This technique utilizes a build platform, powder cartridge and a levelling roller. The build material is spread across the platform. The laser then traces a cross section of the part, sintering the material together. The platform subsequently lowers one layer thickness and the leveling roller pushes material from the powder cartridge across the build platform, where the subsequent cross section is sintered to the previous. This goes on until the component is completed.  Subsequently the replica is taken from the chamber. All excess material is removed and the outer surfaces are polished.

Fused Deposition Modeling (FDM) is a solid-based rapid prototyping method that extrudes material, layer-by-layer, to manufacture a model. The system contains a build platform, extrusion nozzle, as well as control system. The build material, a production quality thermoplastic, is melted and then extruded via a specially designed head onto a platform to make a two-dimensional cross section of the replica. The cross section quickly solidifies, and the platform lowers where the next layer is extruded upon the preceding layer. This continues until the replica is complete, where it is then removed from the build chamber and washed.

Lately more and more wireless wireless surround sound transmitter products have emerged which claim to bring the ultimate freedom of sending music throughout the home. We will look at numerous products and technologies to find out in how far these devices are effective for whole-house audio uses and what to look out for when purchasing a wireless system.

Getting audio from your living room to your bed room can be quite a challenge particularly in buildings which are not wired for audio. Products which resolve this problem are commonly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.

Infrared is restricted to line of sight since the audio signal is broadcast as lightwaves and as a result products utilizing this technology, such as infrared wireless surround sound products, are restricted to a single room.

RF wireless products broadcast the music as RF waves – either by using FM transmission or digital transmission – and can therefore easily transmit through walls. FM transmission is inexpensive but quite prone to hiss, audio distortion and susceptible to interference.

Products which utilize digital wireless audio transmission use a digital protocol. Such products include transmitters from Amphony. In this protocol, before transmission the audio signal is converted to digital data. This method guarantees that the audio quality is completely maintained. Some transmitters employ some sort of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which send the audio data uncompressed will achieve the maximum fidelity.

Products using wireless LAN are useful when streaming audio from a PC. Their drawback is that they typically have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not specifically designed for real-time audio streaming. WLAN receivers frequently do not have built-in network access. As a result, such products often require purchasing separate LAN cards. These cards are then plugged into each receiver.

Powerline products send the audio by means of the power mains and offer great range. They run into problems in homes where there are individual mains circuits in terms of being able to cross over into another circuit. Powerline products have another problem in the form of power surges and spikes which can cause transmission errors. To prevent audio dropouts, these products will commonly have an audio latency of several seconds as a safeguard.

Now we’ll give you some recommendations for shopping for a wireless system: Pick a system that supports multiple wireless receivers if you plan to stream audio to several rooms so that you don’t have to buy a separate transmitter for each receiver. Products with some sort of error correction will be more resistant against radio interference from other wireless transmitters. Select a digital RF transmitter to maintain the original audio quality, ideally one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.

Make sure the wireless transmitter offers the audio inputs you need. You may need amplified speaker inputs, RCA audio inputs etc. Get a wireless system where you can purchase additional receivers later on. You should check that you can get receivers for all the different applications you have. Such receivers may include amplified receivers for passive speakers or line-level receivers for active speakers. If you go with a digital audio transmitter, select one with an input audio level control knob to avoid the music signal from clipping inside the transmitter audio converter. This will ensure optimum dynamic range regardless of the signal level of your equipment.

For high amplifier power efficiency and best sound quality, verify that the amplified receiver has a built-in low-distortion digital amplifier. Pick a system which offers receivers that can drive speakers with the preferred Ohm rating. Make sure the receivers have a small form factor and are easily mountable. This will help during the set up. Products which work in the 5.8 GHz frequency band will have less trouble with wireless interference than products utilizing the crowded 900 MHz or 2.4 GHz frequency band.
