A 3D printer is a great tool invented for the world. There are lots of things you can achieve by using a 3D printer. If you add all of them into a list, you will be able to add many items to the list.
Though there are lots of things you can simply get from a 3D printer, you will be able to add some of the disadvantages like PLA shrinkage too.
The best material for your 3D printer
There are, mainly 02 materials frequently used for getting 3D prints with the shrinkage. PLA, ABS, and Nylon are considered to be the best materials that can be used for the materials of your 3D printer.
You should have a proper understanding of the materials you use for your printer. Those materials have significant characters of their own. The way they act for getting prints may be differed according to the filament materials you get to use.
You should have a thorough understanding of those materials before you approach the printing process.
If you have an understanding of the PLA shrinkage, you will be able to save lots of money along with the time you have to spend.
If you expect to get the 3D print of an element that has elastic characteristics, you will have to use ABS material. Because it is one of the most flexible materials in the world that can be used to get prints of such objects.
Flexibility is not the only thing associated with the PLA filaments. You will be able to get the prints of your desired object in many colors as well. There will be no need to bother with polishing and additives to be used for the print you have managed to take.
Characteristics of 3D filament materials
Even though all those materials are used for different purposes, you will have to realize that those materials consist of similar characteristics as well.
Because you can have all those 03 materials used for similar purposes. Though there are significant qualities for each filament material, you will understand that those things have the same qualities as well.
There are lots of elements inside the filaments and most of the elements are equal to each other.
It’s not always about the chemical nature of the materials, but the physical features as well. If you consider the factor of hardness, all those three have the hardest features. Though the elasticity is less similar to each material, they have the same hardness for most of the times.
Regarding the shrinking factor, there is a huge gap for most of the time. The melting process is one of the most important processes in the printing process. You will see that all those three materials take three different times for melting.
It is not just about the melting, but then becoming solid as well. The curing process is taking a different time with those factors too.
Even though all those three materials have similar qualities in physically and chemically, you will understand that they have three different phases for the curing process.
3D printer’s shrinkage
Shrinkage is an essential part of 3D printing. Because lots of people use a 3D printer for different purposes.
Most of them don’t mind having shrinkage as well. Also, some 3D printers include manual shrinking which can be helpful to the users.
Unlike those, PLA shrinkage is highly expensive to bear. That is not as simple as we can understand. Because making an object without shrinking is a hard process that can take minutes to hours.
All the chemical arrangement and the building has to be done with great care. Because a little error can cause maximum damage. You can simply imagine such an occasion.
There is an object you need to be printed and you just want to shrink. You will have to face many difficulties when making the size smaller than the previous one. If you just cannot do it according to the standard ratio, you will have to tolerate the expenditure that costs to produce that 3D print.
The shrinking process includes the steps of filling the liquid form of the material, melting the filament, and the making of the object you need. It is finalized using the shrinkage.
All these steps take time according to the filament we use. As previously mentioned, machines set the values by themselves. It makes a lot easier for the users than setting manually.
PLA is considered as the best material in the world because of the advantages the users can claim.
It is the best bio-degradable material in the industry.
There is not any environmental pollution associated with the PLA filaments. Though it was expected there would be massive destruction to nature from the latest inventions of mankind, devices like 3D printers have proved them wrong with lots of examples.
Developers use corn-starch like materials to avoid the least effect on the environment. It’s not all about the environmental friendliness of the PLA filaments as nature co-operated raw material for the printers, but there are advantages that a man could expect from a 3D printer.
Price is such a thing any person looking before buying the product. You can buy this material for the least price in the market. The cost of the entire process is likely to be decreased due to that. If you have a look at the price range of the filaments as well as materials in the market, you will understand that PLA material is one of the best products that can be purchased for the lowest price in the market.
Not only that but also PLA material is the best material for taking print outs for the lowest price.
If you have a look at the average speed also, you will mind this PLA material is the best among all others. It does not consist of hard elements that reduce the speed of the printing process.
Temperature for the process is an essential factor for printing. Some materials require a higher temperature for the printing process while PLA filament needs a temperature range from 190 degrees Celsius and 230 degrees Celsius. All these factors together make a nice combo for a printer.
PLA material’s shrinkage
Even though the PLA material has lots of positives, there is just single negative feedback.
It has the highest percentage of shrinking. PLA shrinking is a factor that has been able to reduce the demand of the PLA material. The manipulation has been made difficult for this material. Cooling and low solidification speed factors have caused all those problems.
Though the printing process is very easy to do with the PLA filament, the higher percentage of shrinking has influenced a lot to PLA filament in the market.
It was not properly identified in the market in the early days when the PLA material was introduced to the market.
But, at present, there is an identifiable difference for the PLA filament. If you start producing the items for the international market or the local market, you will feel unpleased because of this factor.
Because the size and the quality of an item you have produced, really matters. If you take an example of yourself, you will realize that this will be a very big deal if you produce spare parts for vehicles. The size and the fitting will differ from minimum to the maximum.
Though there are many advantages associated with PLA material, you will be unhappy to use this material though it comes up with many materials and bio-degradable ability.
You are not supposed to risk your business because of lots of advantages and a small disadvantage. Because a little disadvantage can shrink your whole business. If you intend to purchase this material for your intentions, you will probably have to reconsider your thoughts on having this.
ABS material has the highest shrinkage though.
Most individuals use ABS material as the companion for their 3D prints. It has very impressive advantages like flexibility, less price in the market, and the effectiveness in the industry.
If you are hoping to get a 3D print of a phone casing you will have to use this material as the best priority.
It has long durability as well as an elegant look.
The price of the ABS materials is less than the other materials in the market. That has been a major cause for the use of this material. Because of the content of the material, it has been a good one to resist the shocks and waves.
The flexibility of these materials is being used to create phone casings, key tags, and ornamental items.
There are 02 major disadvantages associated with the ABS filament that can cause losses for you in time and financial.
First thing you need to know about the filament as a disadvantage is the requirement of a higher temperature than the PLA filament. It is the required temperature from 230 degrees Celsius and 260 degrees Celsius to produce the items you need. That can make a huge difference for the goods you are going to produce using a 3D printer.
But, that is not the only thing you should keep in the mind to remember as a disadvantage.
You will have to expect a huge shrinkage for this filament material as well. Though the shrinking percentage is 2% for the PLA material, you will have to expect a larger shrinkage for ABS material as it is about 8% of the actual size.
That has made a bad impact on the entire product and it is not what the 3D printers supposed to do. If you are wondering if this is larger than the PLA shrinkage, it’s not. Because PLA shrinkage is not as affordable as a hardly composed object. But, the ABS shrinkage is applied for objects like phone covers and similar accessories. So, the ABS shrinkage is much affordable than the PLA shrinkage.
Relevant questions About PLA Shrinkage
1)how much does PLA shrink?
The answer for the above query depends on several matters. Even if you are an expert in 3D printing these matters will have to be a set of causes for 3D printing as well. The material you use, the brand name you prefer, color, and other physical features may lead to some kind of shrinkage. The usual or average shrinkage can be considered as 2-5% shrinkage. Like the way it was mentioned earlier, you can either have the above number increased or decreased by changing the usual factors.
2) abs shrinkage ratio 3d printing
It is usual to produce a shrinkage in your 3D printer. But, it is always needed to be kept under your attention how much the shrinkage ratio is. 1.5% to 2.5% shrinkage ratio is nothing you need to worry about. But, an increased percentage of the mentioned amounts may have been caused by several factors such as filament, 3D printer model, auto bed leveling, and other features.
