3D printing for car services

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

We print builds in Hewlett Packard’s branded polyamide. HP PA 12 is more durable and chemical-resistant than ABS and resins.

ABS melts at 105 °C, and HP PA 12 at 187 °C. Since the polyamide is also stress and vibration-resistant, it is often used in the aerospace and automotive industries.

The durability of the build depends not only on the material but also on the thickness of the structure. For best results, follow our pre-printing model preparation guide.

The printer has a build area of 380 × 284 × 380 mm.

If the model is larger than that, it is divided into parts and then assembled. This is how car bumpers and dashboards, architectural models, and sculptures are created. Our online calculator doesn’t divide models into parts, so only project managers can adequately assess the build price in such cases.

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.

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.

Our demo box is a set of items printed with Multi Jet Fusion technology. It includes prototypes, enclosures and casings, moving parts, anatomic models, figurines, and keyrings. 

All of these are printed using HP PA 12. You can check their durability, porousness, as well as their resistance to water, and low and high temperatures. The demo box will help you decide if Multi Jet Fusion technology is the right fit for your project.

At the end of each tour, visitors receive a demo set of printed items, including enclosures, prototypes, mechanism parts, figurines, and souvenirs. You will be able to check those out yourself and show them to colleagues at your company.

You can get a demo box even without visiting our facility—simply send a request for one on our demo sample page.

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

We print builds in Hewlett Packard’s branded polyamide. HP PA 12 is more durable and chemical-resistant than ABS and resins.

ABS melts at 105 °C, and HP PA 12 at 187 °C. Since the polyamide is also stress and vibration-resistant, it is often used in the aerospace and automotive industries.

The durability of the build depends not only on the material but also on the thickness of the structure. For best results, follow our pre-printing model preparation guide.

We guarantee that our printer’s output is safe. The PA 12 polyamide contains no heavy metals, phthalates, and bisphenol A, meaning that it’s safe enough even for toys.

Besides, it meets all European and American biocompatibility and fire safety requirements.

The HP Jet Fusion 5210 uses HP PA 12, a unique material developed by Hewlett Packard. The material retains its properties and shape in a wide range of temperatures: from −50 °C to 150 °C. The PA 12 polyamide is more resistant to high temperatures than ABS: the former melts at 187 °C and the latter at 105 °C.

Since PA 12 also excellently withstands physical stress and vibrations, it is often used in the automotive and aerospace industries. The item’s durability depends on its design and the thickness of its structure. Follow our recommendations on the pre-printing preparation of the model to get optimal results.

For more details about the PA 12 polyamide, see the Hewlett Packard document.

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.

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 print items in HP PA 12 polyamide which enables us to create enclosures and casings with an ingress protection rating of IP67 for dust and water.

The printed items are also unaffected by fine dust. The material retains its properties after contact with rain, water jets, and ocean waves. Additionally, printed items can withstand immersion in water up to 1 meter deep. The polymer has a relatively high density and therefore retains its dimensions in humid and damp environments.

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

We use two coloring methods:

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.

Like Selective Laser Sintering (SLS), Multi Jet Fusion is a powder 3D printing technology. 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.

MJF uses the PA 12 polyamide for printing. As a result, printed items can be made denser and less porous than with SLS. MJF-printed items have isotropic mechanical properties, higher definition, and a smoother surface.

If you need to print an intricate design with thin walls, inscriptions, and logos, Multi Jet Fusion and PA 12 are your best option.

We print items from Hewlett Packard’s branded polyamide. HP PA 12 is more durable and chemical-resistant than ABS and resins.

ABS melts at 105 °C, whereas HP PA 12 melts at 187 °C. Since the polyamide is also stress and vibration-resistant, it is often used in both the aerospace and automotive industries.

The durability of the final product depends not only on the material but also on the thickness of the structure. For best results, follow our pre-printing model preparation guide.
More details about PA 12 are provided in Hewlett Packard’s specifications.

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.
