パラメーターの比較と最適化の提案表

By properly selecting parameter combinations, the 3D printing model can achieve precise manufacturing from concept verification to functional prototypes.

Which printing technology is more stable in high temperature environments? ​

1.3D printing of metallic materials (high temperature environment preferred)

SLM/DMLS (selective laser melting/sintering)

• Heat resistance: Materials such as titanium alloy (Ti6Al4V, melting point 1668°C) and nickel-based superalloys (Inconel 718, melting point 1390°C) can withstand high temperatures for longer than 600° C.
• Stability: The laser melts the metal powder layer by layer, the tissue is compact, and the resistance to creep is strong.
• 3D printing service support: Printing shops reduce residual stress and prevent thermal deformation by optimizing laser power, scanning speed and cooling strategies.

2.Ceramic 3D printing technology (ultra-high temperature resistance potential)

SLA/DLP (light-curing ceramics)

• Heat resistance: Alumina (Al2O3, melting point 2050°C) and zirconium oxide (ZrO2, melting point 2700°C) ceramics can withstand temperatures above 1500°C.
• Stability: Ceramic blanks require high temperature sintering (above 1600°C), density is close to theoretical values, and thermal expansion coefficient low.
• 3D Printing Service Support: Printers provide a complete range of services from printing to degreasing and sintering to ensure that ceramic parts are fissure-free and size stable.

3.High-Performance engineering plastic 3D Printing

FDM (Molten deposition modeling)

• Heat resistant materials: PEEK (melting point 343°C), ULTEM (melting point 335°C) and other special engineering plastics.
• Stability: PEEK retains strength after prolonged use at 260°C, but printing temperature (280-320°C) and cooling conditions need to be optimized.
• 3D printing service support: Printing shops use industrial-grade FDM equipment (such as Stratasys Fortus series) with thermostats to reduce warping.

SLS (selective laser sintering)

• Heat resistance: Nylon + fiberglass/carbon fiber composites with a short-term temperature resistance of up to 180°C.
• Stability: Laser sintering is compact, but oxidizes easily at high temperature for a long time and requires surface coating protection.
• 3D printing service support: Printing shops provide material modification services (such as adding flame retardants) to improve temperature resistance.
• Advantages: Plastic 3D printing is low cost, short cycle time, suitable for medium and high temperature environments (e.g. automobile intake manifolds, electronic radiator, etc.).

Technology selection recommendations for high temperature scenarios​​

How to achieve layered stacking in 3D ink jet printing? ​

Ink jet printing technology is by layering liquid material on top of each other to create three-dimensional objects. Its core lies in high high-precision jetting and curing control. Specific implementation steps and key technologies are as follows:

1.Preparation of materials: Adaptation of liquid media

• Photosensitive resin: The most commonly used material that requires fast curing and high viscosity stability.
• Support material: Water-soluble or fusible material used to temporarily support complex structures.
• Ink jet printing optimization: The injection accuracy of the nozzle (usually 20-100 microns in diameter, for example) needs to be adjusted by adjusting parameters such as viscosity of the material and surface tension.

2.Ink jet print head: Precision droplet injection

Piezoelectric drive or thermal foaming technology:

• Piezoelectric ceramics: The piezoelectric ceramic deformed by voltage changes, and ink cavity are compressed to produce tiny droplets.
• Thermal foaming: Local heating of ink to form bubbles, promote droplet spray.
• Multi-nozzle collaboration: Industrial-grade inkjet print heads integrate hundreds of nozzles to achieve a single sweep over a large area.
• Layered path planning: Software slices 3D models into 2D segments, and the inkjet head spray layers of material along the path.

3.Layer by layer stacking: droplet solidification molding

• Photocuring (UV/LED):
  • After each layer of liquid resin is sprayed, solidify with UV light or LED light immediately to form a solid thin layer.
  • Accurate control: Light intensity and exposure time need to be matched to the solidification characteristics of the material (e.g. SLA/DLP technology).

• Thermal curing: Some materials (such as some nylon powder binders) are heated to initiate cross-linking reactions.
• Multi-layer stacking: Repeat spray curing process until three-dimensional structure is complete (layer thickness is usually 20-100 microns).

4.Post-treatment: enhancement and surface optimization

• Support structure removal: Dissolve or melt temporary support material.
• Surface treatment: Grinding, sanding or chemical polishing to eliminate step effect.
• Late-stage maintenance: Some materials require secondary curing to improve mechanical performance.

How to choose supporting materials for complex 3D printing models? ​

1.Structural adaptation principle​

Overhang structure (>45°):

• PVA/HIPS: Soluble scaffold for water solubility or solvent removal.
• Example: In 3D models printing of inclined bridges, PVA support can be removed by water solubility to prevent tool damage to detail.

Bridge structure (long span):

• ABS/nylon support rods: High temperature resistant to breakage during printing (such as robotic arm model).
• For example, HIPS support can withstand high temperatures when printing grids in 3D models printing to prevent breakage during printing.

2.Matching and separation of materials

Easy peel combination:

• PLA+PVA: Low adhesion, smooth finish.
• Example: The 3D models printing transparent resin model matched the PVA support and dissolved in water without residue.

Chemical dissolution combination:

ABS+HIPS: Lemonin is needed to dissolve the scaffold and is suitable for complex internal parts such as gear components.

3.Actual performance requirements

• Heat Scenario: Ceramic/metal supports: high temperature resistant (e.g. titanium alloy printing) requiring mechanical peeling.
• Shrinkage control: The material shrinkage rate of the supporting material is closer to that of the model material (e.g. PETG + PETG support).

4.Post-treatment efficiency

Quick removal:

• Water-soluble (PVA): Suitable for medium and small size printing, shortening post-treatment time (medium and small size preferred).
• Manual peeling (TPU): Low cost but requires fine handling.

Environmental Protection Plan: It is advisable to select biodegradable scaffolds (e.g. PBDE-based biodegradable materials) to reduce waste liquid treatment costs.

5.Printer adaptation

FDM equipment:

• Co-Supported: PLA/PVA/HIPS, optimize separation effect, optimized separation by adjusting nozzle temperature.
• Example: 3D models printing hollow spheres with HIPS support, acetone vapor smooth surface.

SLA/DLP equipment:

• Supported by soluble resin, it was cured by ultraviolet light and then soaked and removed directly.
• For example, when 3D models printing precision gears, resin supports retain microscopic detail.

FAQs

1.Does SLS printing require support?

SLS printing usually does not require support. The unsintered nylon powder will naturally envelop the model to avoid collapsing in the air. Only a few complex designs require a small amount of ancillary support, which greatly simplifies the reprocessing process.

2.Which technology is suitable for printing transparent parts?

SLA technology is suitable for printing transparent parts. It uses photosensitive resin that hardens under UV light. The surface is smooth and transparent. Suitable for making high precision transparent model (such as optical parts).

3.What does the layer thickness of FDM affect?

The thickness of FDM layer influences surface smoothness, printing time and printing strength. The thicker the layer, the more visible the pattern, the faster the printing, but the intensity may be reduced.

4.How big a part can 3D printing make?

Industrial-grade 3D-printing devices can manufacture large parts of meters (such as aerospace parts), while desktop devices are usually limited to a few dozen centimeters and are suitable for small models or prototypes.
