Frequently Asked Questions

Which plastic is best to use?

Which plastic is best for 3D printing?

After purchasing your own FDM 3D printer, and also during the selection process, you will need to choose the right plastic for 3D printing. But how can you do this if you are new to 3D printing and know little about it? In most cases, the plastic used for 3D printing is the main component for successful reproduction of products. Therefore, we will not skimp on knowledge and will tell you how to choose the best plastic for 3D printing.

Types of plastic for 3D printers

First, you need to consider the types of plastic for 3D printers. Plastic for 3D printing, or filament, is produced in the form of a thin thread with a diameter of 1.75 mm and 3 mm. Most often, 1.75 mm thick threads are used in the basic configuration, but some 3D printer manufacturers offer the option of installing a 3 mm plastic feed system. There are many types of plastic for 3D printing, the most common of which are ABS and PLA plastic.

Plastics for 3D printing: types

Based on popularity in the American market, the following types of plastics for 3D printing can be distinguished:

PLA (polylactide). Organic and short-lived. Suitable for 3D printing of decorative items, but unable to withstand heavy mechanical loads;
ABS (ABS) or acrylonitrile butadiene styrene. Has a long service life and excellent mechanical properties. Heat-resistant and used for industrial purposes. Shrinks when cooling. It is recommended to print in ventilated rooms;
PVA (polyvinyl alcohol). A water-soluble material used as a support;
Nylon. An alternative to ABS plastic, suitable for many engineering structures. When printing with nylon, it is recommended to ventilate the room;
HIPS (High Impact Polystyrene). In terms of physical properties, it is somewhere between PLA and ABS. Printing with HIPS can also produce toxic fumes.

Which filament is best for a 3D printer?

In fact, there are many more types of plastic for 3D printing. These include flexible, fluorescent, and luminescent filaments, as well as wood and metallized materials. However, in practice, such consumables are rarely used and are needed for very specific purposes. Metallized plastics are interesting in themselves, but they are in the early stages of development and are inferior in performance to ordinary reinforced materials. “So which plastic is best for a 3D printer?” you may ask. The choice should be based on specific goals. If you intend to print decorative elements that will not be subjected to useful loads, you can consider PLA plastic. If your goal is to print gears, structural parts, and other items, consider reinforced materials for 3D printing.

What plastic should you print with?

Please note that not every printer supports the entire range of materials for 3D printing. Before purchasing a specific filament, check the specifications of your device to avoid wasting money. The rest is up to you and your imagination. A huge range of colors and shades of plastic are available, including matte and glossy, semi-transparent and completely transparent materials. This variety allows you to create virtually any product to your liking.

Remember, if you need to buy plastic for 3D printing, the Expert3D store is at your service! We offer a wide range of different materials in all possible colors and are ready to advise you on choosing a filament. We look forward to working with you!

What is the cost of manufacturing a product?

3D printing price and profitability

Surely every novice user of a 3D printer, or anyone wishing to purchase one, is interested in the question “What is the real cost of 3D printing?” This is important not only for those who want to build their business, but also for private users who calculate material consumption. No one needs 3D printing that costs more than the likely income from it. Often, this interest arises even before the decision to purchase a 3D printer and accompanies it until the first samples are reproduced. But you can calculate the approximate plastic consumption yourself long before purchasing a printing device. This way, you can avoid 3D printing prices that may unpleasantly surprise you.

The cost of printing on a 3D printer

The cost of printing on a 3D printer is easy to calculate using slicer software. All you need is a 3D model of the object in STL format. Most often, such programs are free. They are often released specifically for specific hardware, but are free and available for download from the Internet. For example, the Cura program allows you to accurately calculate the printing time and material consumption. But first, you will need to set the basic parameters: plastic type, nozzle diameter, etc. After loading the model into the software and setting the necessary values, the program will calculate and display the necessary information about the printing process. This way, you will know the approximate amount of plastic required to manufacture a single product. The data obtained can be easily compared with the price of materials by analyzing average market prices.

The price of 3D printing

As you can see, the price of 3D printing is fairly easy to determine. You can calculate the cost of 3D printing for a wide variety of materials, thus assessing the profitability of using a 3D printer. Don't forget that you can print with different types of plastic, but they are mainly sold in spools of at least one kilogram. Keep this in mind so you don't end up with a huge amount of unnecessary material on your hands. We can note that plastic consumption is not high at all, but you must not forget about support material and filling. If you want to produce high-quality samples, you will have to slightly increase consumption. But this is not critical, we can assure you.

What additional materials are needed?

Additional materials for 3D printing

If you are the proud owner of a 3D printer, congratulations! We are publishing this article for you, as well as for those who are just planning to purchase their own 3D printing device. After all, plastic alone is not enough to work with a 3D printer. You will need a number of additional tools, spare parts, and accessories. All of them are designed to simplify your work, facilitate post-processing of parts, and minimize possible errors in the operation of the 3D printer. In this section, we will tell you exactly what materials you will need for 3D printing. We recommend that you read the information very carefully and take our advice into account.

Accessories for a 3D printer

Perhaps this name is a little strange, but it is the accessories for a 3D printer that play a huge role in the entire 3D printing process. These include:

Blue tape or Kapton tape. One of the most important elements in the system. They protect the work platform from damage, extend its service life, and make it easier for products to stick to the platform.
Special glue to improve adhesion. This material is used when the platform does not have a heating function. Otherwise, it can be used as desired.
Thermostatic device. This is a special device that increases heat dissipation efficiency. It has the shape of a dome, inside which a 3D printer is placed. This material can be used for high-quality 3D printing with ABS plastic;
SD memory card with a capacity of up to 2GB. This is an essential accessory, without which the 3D printer will not print. The control code for the printer is recorded on it. The file system of the storage device is FAT. It is recommended not to print 3D directly from a computer;
Paper clips. Some manufacturers recommend installing a glass surface on top of the standard heating platform. This ensures the uniformity of the working platform and also makes it easier to replace the surface if necessary. The glass surface is attached to the working platform using ordinary paper clips.

Materials for a 3D printer

These include both specialized devices and tools, as well as items that can be found in every home. So, what materials are needed for a 3D printer?

A sheet of A7 paper for calibrating the 3D printer bed. For more details on this process, see here;
Mini spatula. This material will come in handy when separating the finished object from the platform;
Wire cutters and a Dremel tool. Indispensable for removing support material and post-processing products;
Acetone or a special liquid for polishing plastic products. This material is used when working with ABS plastic and materials that are sensitive to acetone vapors. Polishing with acetone allows you to achieve a perfectly smooth, glossy surface on products that is difficult to distinguish from an industrial sample. In addition, acetone helps to glue several parts together or remove cracks in the plastic;
Open-end wrenches and hex keys.

Spare parts for 3D printers

In addition to materials and accessories, spare parts and accessories for 3D printers are an important point that cannot be ignored. Of course, we wish you successful 3D printing and hope that there will be no interruptions in the operation of the device. But in any case, it is useful to be aware of all the possibilities and, when necessary, be able to select the optimal materials for 3D printing. So, here is a list of essential accessories for a 3D printer:

Needle for cleaning the nozzle. Unfortunately, nozzles sometimes get clogged. In this case, it is important to have a “first aid kit” – a special needle of the appropriate diameter;
Spare nozzles. If you cannot save the nozzle with a needle, you will need to replace it. In this case, it is better to have several spare nozzles on hand. For better layer height control, it is recommended to install nozzles of different diameters;
Additional cooling fan. This part is not of primary importance, as it is often already included in the basic configuration of a 3D printer. If the fan is missing or has failed, it will need to be replaced or installed. It is necessary for the timely cooling of the applied layers, which will improve the print quality.
In fact, the listed materials for 3D printing are only our recommendation. You can do without some of them, and you can replace others. During the printing process, you will understand what you need and what you can do without. We would like to remind you that all accessories, spare parts, and additional materials are available in our store. If you have additional questions that we have not addressed, please email us and we will add your questions if necessary!

What is 3D printing?

3D printing – what it is and how it can be used

3D printing technology was patented in the 1980s, but it has only recently gained popularity. New, promising methods have been developed, and the possibilities of 3D technology have reached a whole new level. However, even today, the method is not known in all circles, and not everyone is aware of what 3D printing is. In today's article, we will try to explain in detail and in an accessible way what 3D printing is and where it is used.

In short, 3D printing is a method of manufacturing three-dimensional products based on digital models. Regardless of the specific technology, the essence of the process is the gradual layer-by-layer reproduction of objects. This process uses a special device - a 3D printer - that prints with certain types of materials. More details about it can be found here. Other names for this technology are rapid prototyping or additive manufacturing. The term “additive technologies” is often used to mean “3D technologies.”

Stages of 3D printing

To help you understand what 3D printing is, let's look at the reproduction process step by step. Below are the specific stages of 3D printing. How it works:

3D modeling of the required object is performed according to certain rules;
The file with the digital model is loaded into a slicer program, which generates the control code for the 3D printer;
The necessary 3D printing parameters are set;
The code is written to a removable storage device, which is connected to the 3D printer;
The 3D model is reproduced.

Objects are reproduced gradually. The selected material is applied layer by layer in the required shape, forming the finished product. It is worth noting that the possibilities of 3D printing are virtually limitless, meaning that anything can be manufactured. In some technologies, supports are provided for very thin overhanging elements to prevent them from sagging.

Of course, this is a very simplified description of the stages of 3D printing, but it gives a fairly clear idea of the essence of the technique.

3D printing technologies

Various 3D printing technologies are used to reproduce different objects. They differ in terms of the consumables used, as well as the speed and accuracy of printing.

Let's list the main 3D printing technologies:

Fused deposition modeling (FDM). One of the most common 3D printing technologies, used in most desktop 3D printers and offering an ideal price/quality ratio. Printing is done by layering melted plastic filament.
Laser stereolithography (SLA). The object is formed by layer-by-layer exposure of liquid photopolymer resin to a laser, which hardens under the influence of radiation. One variation of this technology is DLP 3D printing. Instead of a laser, it uses a special projector. Both 3D printing methods are used to create objects with a high degree of detail. In the case of DLP printing, speed is also an additional advantage;
Selective laser sintering (SLS). Reproduction is performed by layer-by-layer melting of a special powder under the action of laser radiation. This 3D printing method is widely used in industry for the manufacture of durable metal elements.

Application of 3D printing

The application of 3D printing is extremely broad. The second name of the technology—rapid prototyping—speaks for itself. 3D printing can be simply indispensable in the manufacture of prototypes and model layouts. It is also a very cost-effective solution for small-batch production. In the aerospace and automotive industries, 3D technologies are already widely used due to their high cost-effectiveness and speed of component manufacturing. Chefs are working on the development of food 3D printers, and in medicine, 3D printing has become something of a technology of the future. With the help of 3D bioprinting, it is planned to produce bones, organs, and living tissues, but for now, 3D printers are used to print implants and full-fledged medicines. Desktop 3D printers can be used for domestic purposes: for repairs, manufacturing various household items, and so on. Designers, fashion designers, sculptors, and artists highly value the possibilities of 3D printing and 3D modeling as an unusual way to realize their talent.
