3D prototyping is a vast technique that involves a series of methods and tricks in it. Manufacturers and suppliers throughout the world depend upon this technique for multiple reasons. It is divided into various further methods that can help you produce quality prototypes.
One of its well-known methods is SLS Rapid Prototyping. It is a technique that is neither old-school nor unreliable. It’s probably one of the best methods of 3D Printing right now. If you are looking to find further details about this topic and how you can use it, this FAQ Guide is your best shot at it.
SLS Prototyping is an essential method in terms of producing prototypes of standard quality. It allows you to produce bulk quantities of sturdy products. No matter how intricate the designs are or how complex the geometry is, the SLS method is going to make everything just right!
So, let’s get started with our SLS Rapid Prototyping facts and details without wasting any further time. After going through this guide, you will know if this is the processing method for manufacturing your products or not.
Before introducing the method, we would like to show you the results it can reach. SLS Rapid Prototyping is known for its complex and quick production. If you hire the best manufacturers or have the best equipment, you can produce almost every delicate prototype with SLS.
SLS Rapid Prototyping does not make it difficult for you to manufacture prototypes. It does not require supports or more manual labor upon the prototypes. So, it would be a superior process method to produce functional and mechanically reliable prototypes of complex shapes and geometry, etc.
If you have a specific prototype in mind about which you are confused, you can contact the manufacturer in China. Tell them the details about your product and how you want it to get manufactured. They will surely help you out. Moreover, the company will also let you know if you can get the prototype manufactured using SLS Rapid Prototyping or not.
This method works by producing the parts layer-by-layer. A polymer powder is used as a conversion material in this process. This powder is fused together into solid parts to manufacture quality prototypes.
You might have heard about powder fusion processes. SLS is one of them. Like SLA Rapid Prototyping, it also uses a laser. That laser is used to transfer high energy into powder molecules. This high energy is transformed into strong and sturdy parts.
Usually, thermoplastic polymers are utilized as the raw materials in the SLS Rapid Prototyping. It is because these polymers are present in a granular form/shape. Their conversion into prototypes is easy and dependable. They are converted into solid layers. A layer over another layer is kept producing until the part is complete.
The process of SLS Prototyping is not complex but takes time to be carried out. It starts with heating up the raw material and the functional base area. But the temperature is kept low. Low enough so that it does not reach the melting point of the functional polymer present in it.
The powder is then spread out over the entire functional area, and the process moves further. Here comes the role of the laser that uses carbon dioxide for sintering the powder. This laser is poured onto the raw material, and it then fuses all the materials together.
After completing this said layer, the process continues with re-spreading the powder on the build platform. This keeps happening until the entire prototype is built. But here, the process isn’t completed.
After the prototype is done, it is taken out, and post-processing work starts. This process in SLS Rapid Prototyping is delicate as it can also result in the breaking of prototypes. This process includes the cooling down, washing, and such similar stuff that can be explained further, too.
The Selective Laser Sintering Method is highly reliable in all terms. It produces great quality and standards of prototypes. The benefits you can get from this process are unlimited too. However, they come with a price, but the price is totally worth it.
Before selecting any process, you must be aware of its pros and cons so that you can use it accordingly. So, if you are looking for some of the main advantages of SLS Rapid Prototyping, some of them are explained here.
You don’t need to put any support in the manufacturing of prototypes during the SLS process. Unlike other methods, it carries out the process on its own. So, you don’t have to go through the typicality and difficulty of using other support parts. All you need to do is let the machines work on their own and process you a very fine prototype.
The SLS Rapid Prototyping has another benefit over other methods. That is the production of all batch sizes. No matter if you are going for a small-scale prototype production business or in need of large-scale batch production, SLS can do it all for you.
Not all 3D Printing methods are good for producing functional prototypes. You need a good and dependable technique for that purpose. SLS Rapid Prototyping is just that. It can produce a good range of functional prototypes that can be used for all mechanical means.
The method of the Selective Laser Sintering process involves good quality materials and techniques. This makes it possible for you to produce intricate designs. No matter how hard the structure or the shape of the prototype is, you can easily manufacture it using the SLS Rapid Prototyping. This is also because it requires no support.
The layers produced have strong adhesion and bond between them. This increases the bond strength to a great extent. Different materials used in SLS Prototyping have different tensile ratios and strengths. You can use the one that offers similar properties that you require for your business.
If you are familiar with the finishing of SLS prototypes, you must know that they have grainy outlooks. This grainy surface is due to the porosity of SLS prototypes. This porosity makes the prototypes easily involved in liquids and easy to dye too. So, if you are looking for prototypes consisting of a long range of colors, SLS Rapid Prototyping is a great technique to opt for.
There are not uncountable raw materials’ ranges present for SLS Rapid Prototyping, but still, there is a lot for you to choose from. The most commonly used materials are thermoplastic polymers in this process.
Some of the most common materials are described below.
This is a material with good qualities and can be used to produce quality prototypes. It offers a great chemical resistance too. So, if you’re looking for some large functional prototypes, it can be a good choice to make. But remember that the prototypes produced by PA-12 have a rough surface finishing.
This polyamide raw material is great for producing elastic and flexible prototypes. Moreover, its isotropic behavior makes the prototypes much sturdier, even if they are flexible to a great extent.
Filled or Glass-Filled Nylon offer great stiffness and temperature resistance. It is good for prototypes that have to go through wear and tear processes or work. They are hard and stiff, so you can rely upon them for tough working chores. Its stiffness is because of its anisotropic qualities. So, if you want flexibility in your prototype, this material is not the one at all.
This PA-FR is a lot similar in properties to the PA-GF because of its anisotropic behavior. Therefore, it can also not produce flexible prototypes. However, if you are looking for stiff, heavy, and strong prototypes, the Polyamide-FR is going to be a great choice for you.
This 3D Printing material is great for producing prototypes with metal touches and appearance. Manufacturing a metallic prototype with a 3D model can be a lot more fun if your product can look exactly the same.
The accuracy ratios of vowin.cn' target='_blank'>rapid prototyping have made it useful for various fields and industries. You can easily make complex designed prototypes using the SLS technique. That is why the industries prefer using it. Different famous applications of SLS Rapid Prototyping are as following.
The industries that manufacture investment casting products prefer this method greatly. It is because you can produce investment casting products of almost all designs through SLS Rapid Prototyping. A large array of investment casting patterns can also be produced through it.
As you know, the materials used in SLS Rapid Prototyping are capable of producing strong and still parts. This quality of SLS is found to be useful in the automotive industry. The parts required in this industry should always be functional prototypes and sturdy. You can easily manufacture them through the SLS technique.
The SLS Rapid Prototyping is helpful in the wind tunnel programs too. Other than this, you can also apply this technique for manufacturing products in the aerospace industry, electronics, and medical industries, military uses, etc.
Both the methods have their own advantages. In some things, 3D printing techniques are more reliable than CNC Machining. While we take into account the size limits, designs, and shapes, CNC would be better than the SLS Rapid Prototyping technique.
Some of the major differences between both methods are discussed below. These differences will surely help you select the better method for your prototype productions.
If we talk about the Labour requirements for both the processes, then SLS Rapid Prototyping will win at the end of this debate. It is because there is no Labour or tough working required in any 3D Printing method, including the SLS Rapid Prototyping.
Whereas in CNC machining skilled operators are a must. Otherwise, the manufacturing process and the post-processing process cannot be carried out at all. Even if you have the best machines, operators are still required to choose between different options to produce the perfect required part.

The parts produced using the SLS Rapid Prototyping method can have complex geometries and larger volumes. But they are limited to a point. However, the complex designs produced in the SLS method are much better than the ones produced in CNC Machining.
But if we talk about strength, tolerance, and sturdiness, CNC Machining would be better. If you are looking for parts with high tolerance, CNC Machining should be your choice. But if you want better geometry and required layer thickness, SLS Rapid Prototyping should be preferred.
Without getting into long debates, the simple thing is, CNC Machining is a lot better at producing large batch productions than any other method. No matter if your large production or just a great number of parts, CNC machining is a lot better than SLS.
Well, now we have landed on the main point. The costs usually depend upon the amount and volume of your parts. If we talk about low volume production, the 3D Printing methods, including SLS, would be a great choice. It will cost less and will help you produce the best quality prototypes with details.
However, for large productions, CNC Machining will be a great choice. CNC Machining can provide you quality prototypes in large production. But there are many factors in both processes that can make either of the techniques more expensive than the other. To know the exact rates and expenses, you should contact a manufacturer company.
Without any doubt, the SLS Rapid Prototyping is the most eco-friendly technique you can ever use. It does not produce any mess, neither while producing the parts nor after the production. Thus, if you are looking for an environmentally friendly method, this is definitely the one.
In CNC Machining, the cutting of metals and the use of complex materials create a whole lot of mess around. Even in the post-processing time in the CNC Machining method, you’d have to face numerous messy methods. A lot of material is left over, which needs to be cleaned or disposed of.
So, the better method depends upon your requirements. But we hope that these above-stated differences and reasons would have helped you greatly in choosing the right method for yourself.
