Workflow of sand 3D printing

Sand 3D printing is an advanced technology for manufacturing metal casting sand moulds, which can achieve rapid manufacturing of complex shaped metal casting sand moulds by combining 3D printing technology with traditional casting process. The following is the general workflow of sand 3D printing:

Step 1: Design the model

First, a 3D model of the part to be cast needs to be created using computer-aided design (CAD) software. This model should contain all the necessary details and geometry, taking into account factors such as shrinkage, cooling and venting of the casting.

Step 2: Print preparation

Selection of material: Select the appropriate sand material and binder according to the needs of the printed part.

Load material: Fill the 3D printer’s silo with sand material and make sure the binder supply is sufficient.

Step 3: Printing Process

Laying the sand layer: the printer’s sand laying device lays a thin layer of sand material on the build platform.

Spraying binder: The print head selectively sprays binder onto specific areas of the sand layer along a path generated by the slicing software. Upon contact with the sand particles, the binder hardens and bonds the surrounding sand particles to form a layer of the model.

Build Layer by Layer: The process of laying the sand layer and spraying the binder is repeated, with the build platform dropping one layer thickness away for each completed layer, until the entire model build is complete.

Step 4: Post-processing

Remove excess sand: After printing, separate the printed sand mould from the uncured sand.

Curing: Place the sand mould in an oven for heat treatment or use other methods to cure the binder to enhance its strength and durability.

Cleaning and dressing: the sand mould is cleaned to remove any excess binder or sand particles and the mould is dressed as necessary to ensure it is ready for casting.

Step 5: Casting

Prepare for casting: Place the cured sand mould in the casting machine and prepare the molten metal.

Pouring the metal: Pour the molten metal into the sand mould to fill the cavities of the mould.

Cooling and demoulding: Wait for the metal to cool and solidify, then remove the metal casting from the sand mould.

Step 6: Subsequent processing

Sprue and Fly Edge Removal: Remove excess metal such as sprues and fly edges from the casting.

Surface Preparation: The casting is ground, polished or otherwise surface treated to achieve the desired surface quality.

Inspection and Testing: Quality inspection and performance testing of castings to ensure they meet design specifications.

How does binder jetting work?

Binder Jetting Process Steps

  1. Preparation

    Material Selection and Preparation:
    The first step in the Binder Jetting process is to select the appropriate materials based on the desired properties of the final object. This can include metals, ceramics, polymers, or composites in powdered form. The materials are prepared by ensuring they meet specific requirements, such as particle size distribution, purity, and any necessary pre-treatments or surface coatings.

    Digital Modeling and Slicing:
    The next step involves creating a digital model of the object using computer-aided design (CAD) software. The digital model represents the desired shape and dimensions of the object. Once the digital model is ready, it is sliced into thin layers using slicing software. Each layer is defined by a set of instructions that the printer will follow during the printing process.

  2. Preparation before Printing

    Print Bed and Powder Layer Preparation:
    The print bed, typically a platform that can be raised or lowered, is prepared for printing. The print bed is calibrated to ensure proper alignment and levelness. A thin layer of powdered material is spread evenly across the print bed using a roller or similar mechanism. The thickness of the powder layer is controlled to ensure precise layering during printing.

    Preparation of Binder Jetting System:
    The Binder Jetting system, which includes the printhead or dispensing mechanism, is prepared for printing. The system is calibrated to ensure accurate deposition of the binding agent. The binding agent, usually a liquid binder, is loaded into the system. The printer parameters, such as droplet size and deposition speed, are set according to the specific requirements of the printing job.
  3. Binder Jetting Process

    Injecting and Bonding of Powder Layers:
    The printing process begins with the selective deposition of the binding agent onto the powdered material layer. The binding agent is injected or dispensed onto the powder bed in a controlled manner, binding the powder particles together in the desired pattern for each layer. The binding agent acts as a binder, solidifying the powder particles upon contact and creating a cohesive layer.

    Layer-by-Layer Object Building:
    After the binding agent is applied, the print bed is lowered (or the printhead is raised) to make room for the next layer. The process of injecting and bonding the powder layers is repeated for each layer, following the instructions from the sliced digital model. This layer-by-layer approach gradually builds up the object until the entire 3D structure is formed.
  4. Post-processing Steps

    Drying and Curing:
    Once the printing process is complete, the printed object may undergo post-processing steps. Excess binding agent and any residual moisture are removed through drying. Depending on the specific materials used, the printed object may also undergo curing, which involves subjecting it to heat or UV light to strengthen and solidify the part.

    High-Temperature Treatment (Optional):
    In some cases, an optional step of high-temperature treatment may be performed. This involves subjecting the printed object to elevated temperatures to further enhance its mechanical properties, such as increased strength or improved dimensional stability. The specific temperature and duration of the treatment depend on the materials used and the desired outcome.

    Note: If metal binder jetting is used to produce parts, after printing, they need to be placed in a specialized oven for high-temperature sintering and debinding before they can form the final usable parts.

    Surface Treatment and Subsequent Processing:
    After drying and curing, the printed object may undergo surface treatment processes to improve its appearance or functionality. This can include sanding, polishing, or applying coatings. Depending on the application and desired specifications, additional subsequent processing steps such as machining or assembly may be performed to complete the final product.

Origins of Metal Binder Jetting

The roots of metal binder jetting can be traced back to 1993 when the Massachusetts Institute of Technology (MIT) developed an inkjet-based process for creating three-dimensional objects using metal powders. It was during this time that the term “3D printing” was coined by MIT in reference to metal binder jetting technology. The manufacturing company Extrude Hone Corporation obtained an exclusive license for this technology in 1996 and went on to develop and commercialize metal binder jetting systems.

What is metal binder jetting? How does it work?

Metal Binder Jetting is a metal additive manufacturing (AM) technology that utilizes powdered materials and a binding agent to create three-dimensional printed metal parts. The process involves spreading a thin layer of metal powder onto a build platform and selectively applying the binding agent using a printhead in specific areas. The binding agent causes the metal powder to coalesce and form a solid structure. This process is repeated layer by layer until the entire metal part or mold is completed.

After printing, the metal binder jetted parts require post-processing steps. This may include removing excess powder, sintering, or heat treatment to improve part density and mechanical properties. Surface finishing and machining steps may also be performed to achieve the desired accuracy and surface quality, depending on the application requirements.

Post-Processing Steps for Metal Binder Jetting

  1. Curing: Curing is the first post-processing step for metal binder jetting. It involves increasing the strength of the green parts so that they can be safely removed from the printing bed. During the curing process, the parts are hardened in an oven at around 200°C for several hours, resulting in much stronger parts.
  2. Sintering: Despite the curing process, the metal parts remain highly porous. Sintering is the next step to reduce the porosity of the parts. The parts are heat-treated in a controlled atmosphere furnace at approximately 100°C for 24-36 hours, causing the binding agent to burn away and the metal particles to fuse together. This results in strong metal parts with low porosity. However, it is important to consider non-homogenous shrinkage during the sintering process.
  3. Infiltration: To achieve high density, the sintered parts need to be infiltrated to fill the voids left by the burned binding agent. This is typically done by applying molten bronze to infiltrate the remaining voids in the part. Infiltration significantly enhances the mechanical properties of the metal parts.
  4. Finishing: The final optional step in the post-processing of metal binder jetted parts is finishing. This involves polishing the part and plating it with gold or nickel, resulting in aesthetically pleasing surface finishes.

These post-processing steps are crucial for enhancing the mechanical properties and surface finish of metal binder jetted parts, making them suitable for various applications.

How long to metal binder jetting parts sinter?

The duration for sintering metal binder jetting parts can vary depending on several factors, including the specific material being used, part size and complexity, sintering equipment, and process parameters. Generally, the sintering process for metal binder jetted parts can take several hours to complete.

During sintering, the parts are heated to a temperature below the melting point of the metal powder, allowing the powder particles to fuse together. The sintering temperature and time are carefully controlled to ensure proper densification and mechanical properties of the final part.

The sintering time can range from a few hours to several tens of hours, with larger and more complex parts typically requiring longer sintering times. Additionally, the sintering cycle may include heating, dwell time at the sintering temperature, and cooling stages.

It’s important to note that the specific sintering time for metal binder jetting parts may be determined through experimentation and optimization for each material and application, considering factors such as part requirements, sintering equipment capabilities, and desired properties of the final part.
