High-precision 3D printing materials suitable for translucent appearance display, translucent structure verification, internal structure observation, and rapid prototyping.
Translucent Resin is a semi-transparent resin material used for photopolymerization 3D printing, suitable for producing product samples that require light transmission, faint internal structure visibility, visual display, or functional verification. It features high molding precision, fine surface, good detail performance, and the ability to achieve a semi-transparent visual effect. However, transparency and light transmission are affected by part thickness, printing direction, layering, support marks, post-curing, and post-processing methods.
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.
It features a semi-transparent effect, fine surface, high molding precision, excellent detail performance, suitable for translucent sample parts, complex structural appearances, and rapid verification of transparent or semi-transparent design effects.

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 | High-precision 3D printing materials suitable for translucent appearance display, translucent structure verification, internal structure observation, and rapid prototyping. |
|---|---|
| Precision performance | Translucent Resin usually has good molding accuracy and is suitable for ordinary appearance parts, translucent structure verification parts, and assembly verification parts. Actual accuracy is affected by part dimensions, printing direction, support position, cleaning, post-curing, grinding and polishing, and surface coating thickness. |
| 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. If semi-transparent parts require sanding, polishing, spraying transparent paint, or UV coating, local dimensions may change. It is recommended to reserve margin for precision assembly positions and perform post-processing if necessary. |
| Minimum Wall Thickness | It is recommended that the wall thickness be no less than 1.0mm. For small non-stressed appearances, localized areas can be about 0.8mm, but large-area use is not recommended. Translucent thin-walled parts are prone to deformation, support marks, and post-processing damage. For large translucent parts, it is recommended that the wall thickness be no less than 1.5mm. |
| Recommended wall thickness | For ordinary semi-transparent exterior parts, 1.2mm-2.0mm is recommended; parts requiring polishing, transparent paint, sandblasting, or transport protection should be appropriately thickened; For large semi-transparent shells, it is recommended to add reinforcing ribs or locally thicken them to prevent deformation and cracking. |
| Minimum aperture | The recommended aperture is no less than 1.0mm. The pores of translucent resin may shrink due to resin residue, insufficient cleaning, or post-curing effects. It is recommended to reserve machining allowance for precision holes, screw holes, and assembly holes, and drill holes later if necessary. |
| Assembly clearance | For ordinary assembly, 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 further polishing, transparent paint, semi-transparent paint, or UV coating are needed, an additional gap of about 0.10mm-0.20mm per side should be added. |
| Detailed performance | Raised text, fine textures, and decorative lines are recommended to be no less than 0.3mm-0.5mm. Translucent materials reduce the visual contrast of some shallow reliefs and fine textures; too small details may weaken during printing, cleaning, sanding, polishing, or spraying. |
| Surface effect | The original surface usually appears semi-transparent, milky translucent, or slightly matte in a translucent light, with slight layering and support marks visible. After grinding, polishing, and applying transparent paint or UV coating, the light transmission and surface gloss can be enhanced; After sandblasting or matte finishing, a more uniform, soft diffuse reflection effect can be achieved. |

High-precision 3D printing materials suitable for translucent appearance display, translucent structure verification, internal structure observation, and rapid prototyping.
Translucent Resin can print parts that are translucent but not fully transparent, suitable for displaying internal contours, verifying translucency, making lampshade samples, or semi-transparent appearance models. Compared to fully transparent resin, semi-transparent resin exposes minor layering, support marks, and internal details less, offering better visual fault tolerance, but it cannot achieve clear transparency or optical-grade transparency.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for Translucent Resin.
Post-processing of Translucent Resin 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 Translucent Resin 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.
For higher clarity and transparency, you can choose Clear Resin – Transparent, CNC acrylic Acrylic (PMMA), or CNC transparent Polycarbonate (PC); If higher impact resistance is required, CNC transparent Polycarbonate (PC) can be chosen; If mass production of translucent parts is needed, injection-molded Polycarbonate (PC), Acrylic (PMMA), Polypropylene (PP), or semi-transparent ABS can be considered; If you only want a regular appearance, you can choose white or black photosensitive resin and apply a spray painting treatment.
If customers mainly care about a semi-transparent appearance, light transmission, subtle internal structure displays, and quick prototyping, Translucent Resin is a suitable choice. If customers require high light transmittance, clear transparency, long-term weather resistance, high-temperature resistance, or genuine mass-produced plastic performance, priority should be given to CNC transparent Polycarbonate (PC), CNC acrylic Acrylic (PMMA), or injection-molded transparent/semi-transparent materials.
