A high-rigidity 3D printing material suitable for heat resistance verification, structural validation, assembly inspection, fixture samples, and high-temperature environment simulation testing.
High-Temperature Resin-Gray is a high-temperature resistant resin material used for photopolymerization 3D printing, offering better thermal stability, rigidity, and dimensional retention compared to ordinary photosensitive resins. It is suitable for producing 3D printed parts that require thermal resistance verification, thermal environment assembly testing, mold samples, jig prototypes, and structural verification in high-temperature scenarios, but it is still not equivalent to high-performance engineering materials such as metals, PPS, Polyether Ether Ketone (PEEK), Nylon (PA) I, etc.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.
Its temperature resistance surpasses that of ordinary photosensitive resins, with good rigidity, dimensional stability, fine surface, and excellent detail performance. It is suitable for thermal environment structural verification and for making high-temperature test samples and jig models.

The following parameters come from product information and material knowledge fields, used for design review, quotation communication, and preliminary judgment before material selection.
| Material positioning | A high-rigidity 3D printing material suitable for heat resistance verification, structural validation, assembly inspection, fixture samples, and high-temperature environment simulation testing. |
|---|---|
| Precision performance | High-Temperature Resin-Gray usually has good molding accuracy and is suitable for standard structural verification parts, assembly verification parts, and jig prototypes. Actual accuracy is affected by part dimensions, printing direction, support position, post-curing, cleaning, heat treatment conditions, and post-processing methods. Dimensions may change after high-temperature testing and should be evaluated based on actual operating temperature. |
| Dimensional tolerances | Standard dimensional tolerances can refer to ± 0.10mm to ±0.30mm. This value is a reference value for conventional processes and does not guarantee the absolute tolerance of all structures. Large parts, thin-walled parts, slender parts, complex structural parts, and parts requiring high-temperature testing may experience larger dimensional deviations. It is recommended to reserve margin for precision assembly positions, and if necessary, perform post-processing or trial assembly verification. |
| Minimum Wall Thickness | It is recommended that the wall thickness be no less than 1.0mm. Small non-stressed areas can be locally reduced to about 0.8mm, but it is not recommended for large-area use. For heat resistance testing, assembly verification, or lightly stressed positions, it is recommended that the wall thickness not be less than 1.2mm, and for large parts, not less than 1.5mm. |
| Recommended wall thickness | For standard structural validation parts, 1.2mm-2.0mm is recommended; for parts requiring heat testing, clamping, assembly, or transport protection, 1.5mm-2.5mm is recommended; for large-size thin-shell parts, additional ribs or local thickening are recommended to reduce the risk of deformation and cracking. |
| Minimum aperture | The recommended aperture is no less than 1.0mm. Small pores may shrink due to resin residue, insufficient cleaning, post-curing, or material shrinkage. It is recommended to reserve machining allowance for precision holes, screw holes, positioning holes, and assembly holes, and to drill holes after processing if necessary. |
| Assembly clearance | For ordinary assemblies, it is recommended to reserve 0.15mm-0.30mm on one side; for movable fits, it is recommended to reserve 0.30mm-0.50mm on one side; if the part requires painting or high-temperature testing later, an additional 0.10mm-0.20mm one-side clearance should be added, taking into account thermal expansion and contraction as well as the effects of coating thickness. |
| Detailed performance | Raised text, fine textures, and decorative lines are recommended to be no less than 0.3mm-0.5mm. Gray materials help observe details and surface contours, but too small details may weaken during printing, cleaning, sanding, or painting. When used for fixtures or test parts, priority should be given to ensuring functional dimensions and structural strength. |
| Surface effect | The original surface is fine, usually gray or dark gray, suitable for observing structural details, edge contours, and surface quality. After grinding, sandblasting, or painting, a more uniform matte gray, industrial gray, or painted appearance can be obtained, making it suitable for sample display and structural confirmation. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.

Compared to ordinary white and black photosensitive resins, High-Temperature Resin-Gray has better heat resistance and rigidity, making it suitable for verifying the shape, assembly, and structural stability of parts when temperature rises. The gray appearance facilitates observation of details, contours, and surface defects, making it suitable for engineering validation, product testing, and customer sample confirmation.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for High-Temperature Resin-Gray.
Post-processing of High-Temperature Resin-Gray affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds High-Temperature Resin-Gray material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If higher temperature resistance and long-term stability are required, CNC machining of Polycarbonate (PC), PPS, Polyether Ether Ketone (PEEK), Nylon (PA) I, or metal materials can be chosen; If better toughness is needed, tough photosensitive resin or nylon Nylon (PA)12 can be chosen; If you need performance close to mass-produced plastics, you can choose CNC ABS, CNC Polycarbonate (PC), or injection-molded engineering plastics; If only ordinary appearance verification is needed, ordinary white or gray photosensitive resin can be chosen.
If customers need to verify the shape stability, assembly relationships, and structural performance of parts at higher temperatures, High-Temperature Resin-Gray is more suitable than ordinary photosensitive resin. If customers need long-term high-temperature use, withstand mechanical loads, contact with high-temperature liquids, or replace real engineering plastics, priority should be given to CNC engineering plastics, metal processing, or mass production material testing.
