Yes. You can visit our domestic factory to observe SLA/SLS 3D printing, CNC machining, and post-processing in person.
Please make a reservation in advance via 1:1 inquiry or email us at support@creallo.com.

A 3D model (STEP, STL, etc.) is required for production.
If you only have 2D drawings (DWG, DXF), we can provide a simplified quote, but actual manufacturing requires a 3D model. We recommend preparing a 3D file before submitting your request.

Creallo has no MOQ (minimum order quantity) – production starts from 1 unit.

However, a minimum order amount applies. If the part cost is lower, the difference will be charged as an additional fee. To reduce additional charges, increase the order quantity or add parts using the same material/color.

Additional costs may vary according to the exchange rate.

A project can proceed only if all model checks return as “Pass/Manufacturable” or “Warning.”

If any other result is included, additional action will be required before production.

AI Result: Pass / Proceed
You can proceed directly to payment.

AI Analysis Result: Warning/Needs Attention 
You may continue with the order once you have reviewed the highlighted issues and agreed to proceed with those risks in mind.

AI Analysis Result: Fail/Cannot Proceed 
The model cannot be manufactured by Creallo. Please revise your design based on the feedback provided and re-upload the file.

Detailed review required  
When the AI analysis cannot automatically determine manufacturability, the status will show as “Detailed Review Required.” Please click the Final Review Request button in the lower-right corner before payment.

Pending detailed review / Under detailed review 
The person in charge is conducting a detailed review. This process usually takes about 15 minutes to 1 day depending on the complexity of the model.

If you paint the product right after receiving it, the layer lines from the additive process may still be visible. Our standard sanding focuses on support removal, so smaller parts or intricate details may not be fully smoothed. 

For the best finish, we recommend performing additional sanding and applying a surface primer before painting.

No. For quality and safety, only verified materials are used per machine specification.

The production direction, bed placement surface, print speed, etc. are set to the optimal production method at the discretion of the production engineer.

If you have a special request, please submit it via 1:1 inquiry.

When using clear resin, the default output is semi-transparent.

By applying surface sanding and transparent finishing to the semi-transparent part, it can be processed into a transparent product similar to acrylic, as shown below.

3D printing is highly versatile. It supports not only rapid prototyping but also small-batch production and bridge manufacturing. From early concept validation to end-use parts, 3D printing can be applied across a wide range of development stages.

Laser cutting and sheet metal fabrication can be quoted using only 2D drawings.

However, due to the complexity of part geometry, CNC machining cannot be accurately quoted from 2D drawings alone.
For an accurate quote, please also submit a 3D file in STEP (.stp) format along with your 2D drawing.

Material options vary by country. Change the production location in the quote page to see updated availability.

No. We only provide CNC machining for new parts.

Click Add Options, select Tight Tolerance, and upload a 2D drawing (PDF) that specifies the required tolerances.

R value in CNC machining refers to the radius of a curve or corner (curvature radius). Since most CNC cutting tools are round, internal corners and curved surfaces cannot be perfectly sharp—they will always be machined with a rounded edge (R value). This is an important factor to consider during design.

As shown in the sample image, while the 3D CAD model may display sharp edges, the actual manufactured part will have slightly rounded corners.

Select Thread in the quote options and upload a 2D drawing (PDF) with thread specifications.

Available options include polishing (for PMMA-like clear parts), painting, silk-screen printing, and other cosmetic finishes.

Vacuum casting is ideal when you need small quantities of parts with consistent quality, or when validating designs prior to injection molding. It offers fast lead times and excellent cost efficiency, making it a preferred method for product developers and engineers.

A silicone mold generally lasts for 15–30 casting cycles (approx. 10–100 parts). Durability varies depending on material properties, curing conditions, and part geometry. For high-consistency requirements, multiple molds may be produced.

Vacuum casting supports a range of polyurethane (PU) materials that mimic the properties of TPU, PC, ABS, and PMMA. This allows you to achieve stiffness, heat resistance, and impact strength comparable to final production parts.

Yes. When tooling costs are a concern, many startups and R&D teams use a combination of 3D printing and vacuum casting to produce low-volume end-use parts.

From master model production to final part delivery, vacuum casting projects are usually completed within 1–2 weeks, making it ideal for fast prototype development.

Due to mold durability and process characteristics, vacuum casting is not suitable for high-volume production. Cycle times are also slower than injection molding. For mass manufacturing, injection molding is more efficient.

Typical tolerances are around ±0.2 mm. Actual tolerances may vary depending on part geometry, and we provide precise guidance during consultation.

Silicone molds for vacuum casting are significantly more economical than injection molds. Although injection molding offers lower per-unit costs for large quantities, vacuum casting is far more cost-effective for runs of approximately 10–100 units due to its low initial investment and short lead time.

We support a wide range of metals including stainless steel, aluminum, carbon steels (SS400, S45C, SECC, etc.), copper, and brass.

Options include standard surface finishing, anodizing, powder coating, glossy/matte painting, and more depending on project requirements.

Sheet metal fabrication is scalable from low-volume to high-volume production. It is suitable for prototypes, pilot builds, and full-scale manufacturing.
