A printing cycle takes 3–5 days. It includes building, cooling, and sandblasting.

At full capacity, printing takes no more than 12.5 hours. If the building volume is only partially filled, the printing time becomes proportionately shorter.

The build cannot be removed from the station immediately after its completion, as the material’s mechanical properties will suffer from flash cooling. In Fast Cooling mode, it takes 4 hours for the build to cool entirely, and in Natural Cooling mode it takes up to 30 hours. Cooling is done in a separate module, so it has no impact on the printing performance.

The HP Jet Fusion 5210 applies polymer in layers of 0.08 mm with a horizontal resolution of 1,200 × 1,200 DPI and a margin of error of 0.08–0.1 mm.

The horizontal resolution is based on the maximum precision of the X- and Y-axis movement of the printhead. The higher the number, the higher the level of detail. Vertical resolution is the minimum thickness of the polymer layer applied in one pass. The thinner the layer, the smoother the build’s surface is.

Multi Jet Fusion produces items gray in color. This is what polyamide powder looks like in finished builds.

However, we can also change the color of the printed item should the client require it. We currently offer two colors: black and graphite. To learn more about coloring, follow this link or contact our manager.

We use several types of materials for printing.

The properties of HP PA 12 polyamide make it possible to create device cases and parts with an IP67 rating for dust and water protection. Finished products are not harmed by contact with fine dust. Physical properties are preserved when in contact with rain, running water, or sea waves. Products made of this material withstand a 30-minute immersion in water to a depth of 1 meter. Due to the high density of the polymer, such products do not absorb water and retain their dimensions in a humid environment.

Because of its non-porous structure, polypropylene (PP) is resistant to water, so products made from this material do not require additional treatment with epoxy resins. The water absorption of polypropylene is very low; kept at room temperature for over 6 months, the material absorbs liquids of less than 0.5% of its own weight, and at 60°C, it absorbs less than 2% thereof.

Thermoplastic polyurethane (TPU) also has high water-repellent properties: per 24 hours at 23ºC, the water absorption of the material is 0.6%, the protection level is IP67.

The completed builds only undergo sandblasting to remove surplus polymer. Optionally, they can also be colored.

We use two coloring methods:

1. Dyeing. The application of color by immersing the item into a reservoir of dye. 
2. Graphite blasting. Similar to sandblasting, but with glass and graphite as an abrasive material. It gives the item a dark-gray color.

Dyeing and blasting are inexpensive and efficient ways of getting a high-quality finish.
Available colors: graphite, black, and gray. Other finishes will soon be made available.

Hewlett Packard recommends the following adhesives for PA 12 bonding:

1. Cyanoacrylate (a.k.a. Superglue)
2. Loctite 401 and 406
3. Epoxy
4. Neoprene-based glues

For better bonding reliability, the item’s surface must first be sanded and cleaned.

See Hewlett Packard’s guide to learn more.

Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) technologies are used for different types of powder 3D printing. Unlike SLS, where the polymer is spot-fused using lasers, MJF fuses the powder and bonding agent with IR light.

For an SLS printer running at 100% capacity, it can take up to 30 hours to fuse and cool the printed product. With MJF, on the other hand, printing takes 12.5 hours, and quick cooling — 4 hours.

Products created using MJF technology have stable mechanical properties and detailed, smooth surfaces. Various materials are used for such printing, as follows:

• Polyamide HP PA 12 allows you to create durable products with complex designs, thin walls, inscriptions, and logos. This material is resistant to water, ultraviolet radiation, and chemicals, as well as being biocompatible.
• Polypropylene is the optimal material for printing prototypes and finished products: car interior elements, cases, boxes, and other items. Polypropylene products are proof against alcohols, oils, ethers, and other chemicals. They are durable and resistant to moisture.
• Thermoplastic polyurethane is suitable for creating flexible elastic products, such as shoe parts, seals, and gaskets. Products made of this material do not crack when deformed and return to their original shape. The material can withstand exposure to oils, solvents, and a number of acids.

Our 3D printing process includes multiple stages:

1. Visualization

The 3D model is imported into HP SmartStream 3D Build Manager, an app that creates printer tasks. The space outlined in blue is the HP Jet Fusion 5210’s print volume. Its dimensions are 380 × 284 × 380 mm. Once the details are laid out, the app starts preparing the print task.

2. Printer preparation

The build unit is loaded with material and then inserted into the printer. Once this is done, it is ready for launch. Your items will be printed from this polyamide.

3. Printing

The printer applies a layer of powder and bonding agent, which is then fused under IR light. Once the layer is fused, the printing head applies another one. With Hewlett Packard’s solution, a whole layer is fused in one pass.

4. Cooldown

The build should be cooled gradually to preserve the item’s structural properties and prevent the material from becoming brittle. Usually, it takes up to 12 hours for a build to cool down. Meanwhile, the HP Jet Fusion 5210 can print another one. The printer also has active cooling capabilities: the build can be cooled in just 4 hours, but there is no guarantee the material will be as durable.

5. Clean-up

Multi Jet Fusion is a powder printing technology, so the newly built items need to be cleaned from surplus polyamide. All this is done in the post-processing unit.

Once cleaned, the items are ready for use without additional finishing. They can also be dyed black or gray if need be. Then we send them to the customer.

You can pay for your order once our manager clarifies all the details with you. Infomir 3D Printing fulfills orders only on pre-paid terms. You can pay for your order with a PrivatBank card or cashless payment.

For cashless payments, we need the client to submit their registration certificate, VAT payer’s certificate, and banking details. After the order is paid for, we will deliver the finished items together with an invoice.

The price depends on the weight and quantity of items. These determine how much polymer is used.
