DED is known for its precision and ability to build parts with complex geometries directly onto existing components, making it ideal for industrial applications like aerospace and automotive. This process operates within a controlled environment to prevent oxidation and ensure material quality. DED stands out for its capability to handle large-scale and high-strength materials, though it often requires post-processing for finishing. |
| Deformation Compensation Deformation compensation is the process of adjusting a 3D model’s design to counteract warping, shrinkage, or other distortions that occur during printing. This is particularly important when working with materials like ABS, which can shrink unevenly during cooling. By pre-deforming the digital model in the opposite direction of expected distortions, users can ensure the final print matches the intended design. Advanced simulation software can predict deformation and provide automated compensation adjustments, streamlining the process for complex or critical components. This technique is widely used in industrial applications where dimensional accuracy is paramount. |
| Delamination Delamination refers to the separation or splitting of layers in a 3D-printed object, a defect that compromises the part's structural integrity and strength. This issue typically occurs when interlayer adhesion is weak, often due to insufficient nozzle temperature, incorrect layer height, or improper cooling settings. Delamination is especially common in high-temperature materials like ABS, which shrink during cooling, causing layers to pull apart. To prevent delamination, users can increase the nozzle temperature, use a heated bed or enclosed printer, and optimize slicer settings for slower cooling. Proper calibration and material storage also help minimize this problem. Delamination must be addressed when printing functional parts to ensure they perform as intended under load. |
| Density Gradient Infill Density gradient infill is a specialized infill strategy where the density of the infill varies across the model, typically becoming denser near critical load areas or surfaces that require more strength. This technique helps optimize material usage and print time while maintaining structural integrity where it matters most. For example, the center of a model might have a low-density honeycomb pattern, while areas near mounting points or edges might use a higher-density structure. Advanced slicers allow users to customize these gradients based on the intended use of the part. Density gradient infill is especially useful in engineering applications where weight reduction and durability are critical. |
| Deposition Rate Deposition rate refers to the amount of material extruded by a 3D printer per unit of time. It is a critical factor in determining print speed and part strength. A higher deposition rate allows for faster printing but may reduce surface quality and precision, while a lower rate produces finer details at the cost of increased print time. Deposition rate is influenced by factors such as nozzle diameter, filament type, and extrusion temperature. Balancing deposition rate with other parameters ensures optimal performance, especially for large or detailed models. |
| Depowdering Depowdering is the process of removing excess powder material from parts printed using powder-based 3D printing technologies like Selective Laser Sintering (SLS) or Binder Jetting. After printing, the parts are surrounded by loose, unfused powder, which must be carefully extracted to reveal the final object. This step is typically performed using brushes, compressed air, or specialized depowdering stations equipped with vacuum systems. Proper depowdering ensures that fine details are preserved while minimizing material waste, as the recovered powder can often be reused in future prints. It is an essential post-processing step for achieving clean, functional parts, especially in industries like aerospace and healthcare, where precision is critical. |
| Design for Additive Manufacturing (DfAM) Design for Additive Manufacturing (DfAM) refers to a specialized approach to designing objects optimized for 3D printing.

Design validation is widely used in industries like aerospace, automotive, and consumer goods, where precision and functionality are critical. It ensures that the final product will perform as intended before committing to mass production. |
| Dimensional Accuracy Dimensional accuracy in 3D printing refers to how closely a printed object’s dimensions match the original CAD design. It is a critical metric for applications where precision is essential, such as engineering parts, prototypes, or assemblies. Dimensional inaccuracies can arise from factors like material shrinkage, over-extrusion, poor calibration, or environmental conditions. To achieve better accuracy, users can adjust slicer settings (e.g., flow rate, nozzle temperature), calibrate the printer’s axes, and compensate for material-specific behaviors. High-end printers often include features like closed-loop systems or advanced sensors to enhance accuracy. Regularly testing with calibration models ensures consistent results, especially when working on tight-tolerance projects. |
| Dimensional Compensation Dimensional compensation refers to adjusting slicer settings or design parameters to account for deviations caused by material shrinkage, over-extrusion, or thermal expansion during 3D printing. For example, users might slightly oversize or undersize a model to ensure that the final print matches the desired dimensions. This is particularly important for engineering parts that need to fit together precisely. Many slicers include compensation settings, such as tolerance adjustments or scale factors, to help users fine-tune prints. Dimensional compensation is critical for achieving accuracy in applications requiring tight tolerances, such as mechanical assemblies or prototypes. |
| Direct Drive Extruder A direct drive extruder is a filament-feeding system where the extruder motor is mounted directly on the print head, providing better control over filament flow. This setup is especially effective for flexible filaments like TPU or TPE, as the shorter filament path reduces the risk of tangling or under-extrusion. Direct drive systems are generally more precise than Bowden setups but add weight to the print head, which can limit print speed or introduce vibrations on fast-moving printers. They are favored by users who prioritize versatility and high-quality prints over speed. |
| Direct Extrusion Direct extrusion is a filament-feeding mechanism where the extruder motor is mounted directly on the print head, pushing the filament directly into the hot end. This design offers better control over extrusion and retraction, making it ideal for printing flexible or soft filaments like TPU or TPE.

However, the added weight of the extruder on the print head may limit print speed and introduce slight vibrations on fast-moving axes. Direct extrusion is widely favored by hobbyists and professionals who prioritize versatility and print quality over speed. |
| Direct-To-Part Manufacturing Direct-to-part manufacturing refers to using 3D printing to produce final, end-use components without the need for intermediate steps like mold-making or machining. This approach leverages the flexibility of additive manufacturing to create complex, custom, or low-volume parts quickly and cost-effectively. Direct-to-part manufacturing is particularly valuable in industries like aerospace, where custom parts with intricate geometries are often required. The ability to print parts directly from CAD files reduces lead times, minimizes waste, and allows for rapid iteration. However, achieving consistent quality often requires post-processing steps such as surface finishing or heat treatment. |
| Displacement Compensation Displacement compensation is the process of adjusting a 3D printer’s movements to account for inaccuracies caused by mechanical issues like backlash or thermal expansion. These adjustments ensure that the printed object matches the intended dimensions and geometry. For instance, compensating for backlash in the X or Y axis prevents slight offsets that can distort details or dimensions. Modern slicer software and printer firmware often include displacement compensation features, allowing users to fine-tune their printer’s performance. This is especially important in engineering or prototyping applications where precision is essential. |
| Displacement Mapping Displacement mapping is a 3D design technique used to add fine details to a model’s surface by modifying its geometry based on a texture or height map. Unlike bump mapping, which only simulates detail visually, displacement mapping physically alters the model’s mesh, making it suitable for 3D printing. This method is ideal for creating intricate patterns, such as embossed text, raised logos, or textured surfaces, without manually modeling each feature. Displacement mapping is commonly used in artistic, architectural, and decorative applications, where detailed aesthetics are important. It is supported by many advanced CAD and 3D modeling tools. |
| Dissolvable Supports Dissolvable supports are a type of support structure printed with water-soluble or chemical-soluble filaments, such as PVA (Polyvinyl Alcohol) or HIPS (High Impact Polystyrene). These supports are used in dual-extrusion 3D printers, where one nozzle prints the model and the other prints the support material. After printing, the supports can be dissolved in water or a specific solvent, leaving the model with clean surfaces and intricate details intact. Dissolvable supports are particularly beneficial for printing complex geometries, internal cavities, or overhangs that would be difficult to remove manually. While they increase material costs, their convenience and precision make them popular for professional and engineering applications. |
| Distributed Manufacturing Distributed manufacturing is a production model where parts or products are 3D-printed at multiple decentralized locations rather than a single centralized facility. This approach leverages the flexibility of additive manufacturing to reduce transportation costs, shorten lead times, and enable on-demand production. Distributed manufacturing is particularly useful in scenarios like remote supply chains, emergency medical supplies, or custom parts for consumers. Cloud-based platforms often facilitate this model by sharing designs and coordinating production across a network of 3D printers. |
| DLP (Digital Light Processing) DLP, or Digital Light Processing, is a resin-based 3D printing technology that uses a digital light projector to cure photopolymer resin layer by layer. The projector emits an entire layer of light at once, solidifying the resin in the desired pattern, making DLP faster than SLA (Stereolithography) for many prints. DLP printers are renowned for their ability to produce highly detailed prints with smooth surfaces, making them ideal for jewelry, dental applications, and miniatures. The resolution of a DLP printer depends on its projector’s pixel size, with finer pixels delivering more precise details. Post-processing, such as washing and curing, is essential to enhance the final print’s durability and appearance. Although more expensive than FDM printers, DLP is highly valued for its precision and quality. |
| DMLS (Direct Metal Laser Sintering) Direct Metal Laser Sintering (DMLS) is a metal 3D printing technology that uses a high-powered laser to fuse powdered metal layer by layer.
