Premium Surface Finishes for Rapid Prototyping
Generally, the surface finish for our rapid prototype parts is selected based on the customer’s requirements. If there are no special requests, we use the ‘as machined’ finish
Polishing
The surface of the part transitions from rough to smooth and refined. For transparent materials, the clarity increases significantly after polishing.
Chemical Smoothing
This nearly eliminates visible layer lines, leaving a smooth surface with a natural luster. Surface roughness can be reduced by more than 80%.
Sandblasting
This removes tooling marks, resulting in a uniform, non-reflective matte finish or an even satin finish with a smooth, delicate texture.
Brushed Finish
This gives your metal prototype a surface with regular, fine lines (either straight or a random, swirling pattern) and also helps hide minor scratches.
Anodizing
This creates a protective layer that can be dyed in a wide variety of colors, available in either glossy or matte finishes.
Spray Painting
This covers the base color and surface imperfections, allowing you to achieve any color and various special textures, such as a leather-like texture or a soft-touch rubber-like feel.

FAQ For Rapid Prototyping Services
What is the pricing standard for Logell Mold’s rapid prototyping services?
For CNC and vacuum casting, we mainly decide the price based on the part size, machining time, and material waste.
For rapid tooling and injection molding, the price depends on the part size, tooling structure, and the estimated tool life (number of shots), plus the material.
For 3D printing, we determine the price based on the part volume, support structures, and the machine type (industrial-grade SLA, SLS, or FDM).
How long will it take to receive a prototyping quote?
For any process, our manual quotes usually take one day. If it falls on a weekend or other special cases, it may take up to 48 hours.
A manual quote is more accurate. If you prefer a rough estimate first, you can use our price calculator (available for tooling, injection molding, and CNC machining).
Can you provide small-batch production after prototype validation?
Yes, we can. Our service supports the journey “from prototype to production.”
After you approve the prototype, we recommend using our factory for small-batch production. You can choose vacuum casting or CNC
machining for 10 to 100 units. For medium volumes (100 to 5,000 units), we recommend rapid injection molding.

Is there a minimum order quantity for prototypes?
Since we are a rapid prototyping service provider, we certainly have no minimum order quantity (MOQ) requirements.
What CAD file formats do you accept?
We recommend you use STP (STEP) or IGS file formats. These formats preserve the original surface data best and are less likely to have missing surfaces. We also support STL, X_T, SLDPRT, and other formats.
If you only have 2D drawings, we recommend that you obtain 3D drawings before working with us. Our company currently does not provide modeling or product design and development services.

What are the standard tolerances for different rapid prototyping processes at Logell Mold?
For CNC parts, we follow the ISO-2768-M standard. The typical tolerance is ±0.127mm (±0.005″). For extreme precision, we can achieve tolerances of ±0.0254mm (±0.001″).
For 3D printing (SLA/SLS), the typical tolerance is ±0.127mm (±0.005″).
For injection molded parts, we strictly follow the DIN-7168-M standard. The typical tolerance is ±0.1mm (±0.004″). Under extreme precision conditions (depending on the mold), injection molding tolerances can reach ±0.05mm (±0.002″).

If design modifications are needed after prototype testing, will the cost of a revised quote be high?
Not exactly.
If the design changes involve minor dimensional adjustments or local modifications, we usually provide a revised quote for free. We only charge for the extra machining time or material cost. If the design changes involve a major structural overhaul, we will issue a new quote based on the new design complexity.

Will you provide suggestions on my 3D design?
After we receive your drawings, our team will conduct a DFM (Design for Manufacturing) analysis during a project meeting.
If we find issues such as unsupported structures, fragile thin walls, insufficient draft angles, or assembly interference, we will proactively include a “Design Optimization Proposal” with the quote. This helps you avoid later trial-and-error costs.
