FAQ

Yes. We have a wide range of products. Our sales staff will make a proposal based on what kind of 3D modeling you would like to do.

Support is available. Depending on the model, “paid training” may be available as an option. If you study on your own, it is easy to get stuck in the middle. This training is very popular because it allows the person in charge of the operation to work on the 3D printer with a good understanding of it.

“Filament”, “Plate surface sheet” and “Nozzle” are the main consumables for MEX type printers.
If any of the parts are damaged due to mishandling, etc., each part must be purchased.
*SLA type is described in the “SmaPri part”.

Materials (filament, resin, syringe), PC (used for 3D data conversion) 3D data conversion software (available at no charge for each machine), 3D data (extension stl) etc. are required. If you are unable to create 3D data, we can create 3D data and convert it. (Consultation required).

Delivery will be made by general route delivery service. Please note that time cannot be specified.

No, we don’t handle metal 3d printers.

No. We don’t support that.

Yes, we do. For 3D printers that require ancillary equipment such as SLA, we also sell ancillary equipment, so please consult with our sales staff.

Yes, we can introduce a leasing company. It is an operating lease. In the case of finance leases, the customer is responsible for confirming the lease.

Our sales staff will be available for consultation.
Our sales staff will make a proposal including what the customer wants to work on with the 3D printer, examples of 3D printer applications, and the characteristics of each method of fabrication.

Yes, we will provide you with a “modeling report” that includes modeling time, material costs, and modeling conditions.

You can confirm this by doing the ‘3D printing service’ before installing a 3D printer.
If you send us your 3D data, we will do the printing service.

Our slogan is “from prototyping to mass production,” and we are able to provide a comprehensive range of services. Our core business is rubber and plastic extrusion molding, and we also offer compression molding and injection molding services through our network. We are also able to propose shapes and materials based on our expertise in materials and molding, since we have been manufacturing rubber and plastic products for a long time. Please contact us for more information.

Yes. If you visit our showroom at our Kuki factory, we can show you the model you have requested being printed. Advance reservations are required for this service.

If you provide us with 2D drawings, we can convert them into 3D data. If it is not too complicated, we can also create data from a sketch drawing, so please contact our sales representative.

Convert your data to STL data. Import the STL data into the dedicated slicer software (free software) that is available for each model. After that, the modeling conditions are set, the modeling data is extracted, and the data is transferred to the printer via USB memory, Wi-Fi, etc.

Stacking pitch” and “extrusion width” are used in the MEX method. Stacking pitch” is the height of stacking in the 3D Z-axis direction. It can be as small as 0.01mm. The most commonly used pitch is 0.2mm. It is a good balance between molding time and quality. Extrusion width is the thickness of the line when the object is viewed from above. It is affected by the nozzle diameter. In most cases, a 0.4mm nozzle is installed as standard. Optional products such as 0.2mm nozzles are available.

We can accommodate up to 1000x1000x1000mm” size. (depending on the material). For long products, we can also accommodate “lengths of approx. 3000 mm”. (Mainly PLA) Please use this service to examine the shape of long parts such as sash shapes, rail shapes, etc., and to check the secondary processing.

A wide variety of materials are available.
PLA, ABS, PC, PP, PA, super engineering plastic (PEEK, PEI [ULTEM], PPS), soft (100% liquid silicone rubber molding, rubber-like soft resin), Luminous materials, SLA (acrylic material-based general industrial materials, ABS-like, rubber-like, washable resin, dental materials, high transparent materials), etc.
We can also handle long products (approx. 3000L in length) and digital graining (graining on the surface of the modeled object).
For more information, please see the “3D Printing service” page.”

We provide 3D printing services. In principle, we can provide a quotation if you send us (1) STL data, (2) material, and (3) number of pieces. Since the infill ratio and stacking pitch vary depending on the application, we would appreciate it if you could also provide us with information on the intended use of the product. Please feel free to contact us.

Yes. We can provide a full range of services from “prototype production” to “mass production”. [Prototype] 3D modeling. [Mass production] Extrusion molding, injection molding, compression molding. We can also provide consultation from the stage of shape consideration.

Depending on the nature of your inquiry, we can solve your problem through direct communication with our technical staff online, such as in a web meeting, or our sales staff can visit you to explain the problem. (There may be a charge for this service.)

First, please contact the HOTTY Polymer Sales Dept. In case of failure, the 3D printer will be placed in the packaging box and sent back (send the machine by courier service and return it after confirmation). We will use the packing box that the 3D printer came in, so we would appreciate it if you could keep it instead of disposing of it.

It is a “string-like material” used for 3D printer MEX system, etc. It is the equivalent of “ink” in a general copy machine. Filament is generally sold wound on a reel. The image of filament is similar to that of thread wound on a bobbin for a sewing machine. Please feel free to contact us even if you do not understand 3D printer terminology.

Yes. We can produce special filaments using our core technology of extrusion molding. Please contact us for more details. Please contact us for details.

Direct sales are also available. Please select the method that is easiest for you to work with.

Some models can be used if the filament size match the specifications. Please note that machine manufacturers may not guarantee the use of filaments other than genuine filaments.

It is easier to use with “direct extruder” models but some models have not yet been tested for printing. On the other hand, the “Bowden” models are difficult to model. Please feel free to contact us for more information. *Direct extrude: Models in which the extruder is built in close to the nozzle *Bowden: Models in which the extruder is built into the machine frame or away from the nozzle.

Yes, we can provide standard samples. If you provide us with STL data, we can make it, so please contact our sales representative.

We can provide physical property data for the silicone material used in “innovatiQ LiQ320”, but we cannot provide physical property data for the material used in “SILICOM” because the product has not yet been released.

Currently, “SILICOM” 30° (JISA) and “L320″ 50° (JISA) are available. SILICOM” will be added to the hardness lineup in the future.

Since it is not possible to attach a support material, we use our patented technology of “cross-linking,” in which data is divided and modeled, and each part is joined using the same material used in the modeling process. Because the same material is used, there is no change in material quality, and the integrally processed modeling object has the same strength as the 3D printed modeling object. Please note that the appearance of the cross-linked joints is different from that of normal modeling.

The curing methods of the materials are different. “SILICOM” is UV curable and “innovatiQ LiQ320” is thermoset. Please feel free to contact us for details.

Yes. There are two types of film: film for resin vat and film for LCD protection. The film for the resin vat should be replaced when it can no longer be successfully modeled. LCD protection film should be replaced when it becomes dirty due to resin adhesion, etc.

It varies depending on the resin, but is approximately JPY30/g to JPY40/g.

Shape reproducibility will be reduced. Transparency is not considered to be affected. The molding data used in optical 3D printers is generated based on STL data. STL is a data method that reproduces a three-dimensional shape as a set of fine planar triangles (positional information). Therefore, the output accuracy is low, and the larger the number of triangles, the lower the reproducibility of curved surfaces. Reference URL:

If the resin is not used immediately after molding, it is recommended to put it back into the light-shielded bottle provided to prevent deterioration. We will explain how to put it back in the bottle during the training session when the machine is introduced.

Each color has some characteristics. White tends to reproduce data better, while black tends to expand slightly.

This is a liquid resin material used in the 3D printer optical modeling method. We use “UV curing” materials that harden when exposed to ultraviolet light.

0.6 mm or more. However, depending on the data, it may be possible to reproduce data as small as 0.6 mm. In one of our tests, we were able to reproduce pillar structures up to about 300 µm and hole structures up to about 400 µm. Please contact us for more information.

In winter, the machine and resin tend to be colder and more difficult to fix unless inside a well-heated room. Please make sure to bring the room temperature up to room temperature before molding so that the machine and resin are under room temperature.

Spray paints for plastic models are easy to work with, and paint can be applied relatively cleanly.

Since the material is acrylic resin, it can be bonded by using an acrylic adhesive. Please contact us for a more detailed answer.

The DLP method uses a projection lens system, which tends to distort the image except at the center, but the SmaPri uses the LCD method, which does not use a lens system and directly illuminates LEDs without distortion. Another feature of SmaPri is that it is inexpensive because it uses LEDs (liquid crystal displays), which are widely distributed in the market.

The SLA system uses point irradiation, which causes distortion at the edge of the molding area. On the other hand, the LCD type uses surface irradiation, so there is no distortion within the modeling area. For example, when multiple models are modeled within the modeling area, the SLA type produces uneven results depending on the modeling area, whereas the LCD type produces beautiful models with no variation in any area.

Yes. We also handle compression and injection molded products. We can also offer integrated services from molding prototypes to mass production using 3D printers, so please feel free to contact us using the inquiry form.

When burned, the material becomes ceramic while retaining its shape to a certain extent, thus reducing the penetration of flames and smoke even if it burns. It also has low smoke emission, which can reduce the deterioration of visibility due to smoke emission.

The details are a secret, but this is a special technology that considerably shortens the original process. It is environmentally friendly as it eliminates adhesive materials.

For inspection purposes, ID0.2 mm is the minimum.

We are sorry, but only standard black products are available.

“Nonbee” absorbs water slowly over a certain period of time, so it is impossible for it to absorb water rapidly and expand.

It can be changed depending on the formulation (from 3 times to about 10 times). Expansion rate is based on volume ratio.

We can manufacture the product using transparent materials such as silicone rubber, TPO (olefinic elastomer), vinyl chloride, and acrylic elastomer. However, afterglow brightness and other values vary depending on the material. Based on our experience, silicone rubber tends to have better performance. Please consult with us.
