INAC US’s Tech Strength Series 02
A special section introducing our one-of-a-kind technology
The theme of the second feature is “A 3D printer for stylish and detailed parts!”
We propose the best transparency products by selecting the optimal conditions and processing methods for your particular use case.
INAC’s wide range of technologies enables us to produce all sorts of transparent parts using 3D printers.
The best feature of 3D printers is that they can create undercut and hollow shapes in one piece, which is impossible with conventional cutting. Bottle shapes like the one in the photo can be produced in one piece, allowing the contents to be visible without risk of liquid leakage.
Another great feature is the short delivery time. Since there is no need to arrange materials or create processing programs, we can respond to urgent orders as long as we have 3D data.
This method is ideal for when you just need products quickly.
3D printers are attractive for their freedom of design, but products that have just come out of the printer still have supports and traces of lamination, and are not very appealing to look at.
At INAC however, we use our accumulated experience in techniques such as polishing, yellowing removal, and transparency processing to achieve a beautiful finish, so creations can be used for various purposes such as for creative design parts.
We can also make products transparent even when the inside is inaccessible, such as the case with bottle shapes.
Please consult with us even for designs that you have previously given up on as being unfeasible to produce.
3D printers are easy to use, but it is surprisingly difficult to make them work the way you want them to. And when it comes to finely detailed fabrication, simply reducing the laser diameter is not enough to reproduce shapes perfectly.
INAC’s operators are familiar with equipment of a wide variety of parameters and are able to maximize performance. Leave it to use to produce difficult shapes such as fine brushes.
High clarity (bubble-free)
* Due to the production method, fine air bubbles may be present in rare cases.
Colorless (high transparency)
Visible light transmittance: 90.4% (10mm thickness)
Refractive index: 1.512 (wavelength 587.562 nm/horizontal direction) K7142 compliant
Heat resistant temperature: 53°C (low load) K7191
Hardness: D83
The combination of “Highly transparent material” + “Elimination of yellowness” will result in the production of clean transparency and sharp edges.
Use the products as high-quality design models.
We faithfully reproduce complex shapes that are difficult to manufacture by cutting, giving
Models for design review
These can be delivered in an ultra-short delivery time, so they can be used to shorten the time for design decisions. We even have a track record of next-day delivery.
Internal validation models
These can be used for quick cause investigation and verification, such as for quality improvement and design changes. Being able to directly observe internal operation and interfering parts can result in validation with confidence.
①Detailed meeting (We will visit your company or have a meeting through an online platform such as Zoom)
The meeting will include an explanation of the production method, among other topics, based on the purpose of use and specifications.
Depending on your request, we will provide samples and conduct a simple investigation of the resistance to chemicals and the like to which the product is to be exposed.
②We will ask you to supply 3D data.
③Creation of programs for 3D printer output ← Our know-how
We aggregate many 3D printer output parameters and program them with specialized software to determine how the product shape will be formed.
④3D printer output
The shape is completed by irradiating the part to be shaped with UV laser light and repeating stacking. In general, the lamination pitch is around 0.1-0.15mm with the minimum being = 0.05 mm. If the lamination pitch is finer, it may look nicer, but it would take more time, so a balanced approach is important.
⑤Completion of 3D printing output
In order to maintain the shape of the product during output, “support structure” is added while printing. After printing, the product is cleaned to remove the unnecessary “support structure”.
⑥Finishing touches
Layer ridges are removed by hand finishing in order to create a smooth surface.
If transparency is not required, the product is delivered in this state.
⑦Finishing touches using clear coating (Completion)
Clear coating creates a clear and transparent product.
①Detailed meeting (We will visit your company or have a meeting through an online platform such as Zoom)
We will inquire about your use cases and special requests, and then decide production specifications such as finishing level and decoration.
②We will ask you to supply 3D data.

③ Creation of programs for 3D printer output
We can accommodate from the minimum lamination pitch of 0.05 mm. Optimal programming is performed in consideration of the balance between precision and delivery time.
④ 3D printer output
We set the parameters for the 3D printer to output the product, taking into consideration the environment at the time of production, including UV laser beam diameter/output, material level control/coating conditions, environmental temperature/humidity, among other conditions.
⑤ Finishing and clear coating
Unnecessary “support structure” will be removed and the product finished, and if required, a clear coating will be applied for transparency.
* We select clear coating depending on the usage.
⑥Final shipping inspection
We deliver the products to our customers after visual inspection and measurement so that they can use them with confidence.
We also check the fitting of the parts ordered as an assembly before shipping.
This is an original design of an automobile front grille.
Transparency processing and masking paint were applied to the 3D printed model.
Product size: 400 x 800 x 155
The maximum molding size is 600 x 800 x 400.
Large parts with undercuts can also be processed in one piece.
Our company also offers painting and vapor deposition plating in-house which enables us to freely combine 3D printing and decoration.
The condition of the substrate greatly affects the finish of the painting, so we are proud that one of our strengths is that we apply an appropriate substrate treatment to best suit the post-processing.
We will decorate according to your requests which may include, for example, toning to match a color sample.
Please feel free to contact us for mock-up production.

Liquid casting material is injected into the silicone rubber mold in a vacuum environment.
The silicone mold is cut open into a male and female mold, and the master model is removed.
The master model is fixed to a wooden frame and silicone is poured to create a mold.
