    In recent years, 3D printing has gained widespread popularity
    in the modeling industry, particularly for accessory production.
    A few years ago Eduard, too, embraced this technology, gradually
    replacing traditional casting methods with direct printing,
    constituting approximately 80% of our Brassin production.
    Removing Supports: Cut supports using a sharp scalpel, razor saw, or ultrasonic knife.
    The primary advantage of 3D-printed
    accessories lies in their simplicity, with
    fewer parts enhancing user-friendliness
    in terms of assembly. Unlike cast kits that
    suffer from shape instability due to mold
    degradation, 3D-printed parts maintain
    dimensional stability.
    Here's an overview of working with our
    3D prints, simple activities suitable for
    modelers of varying skill levels.
    The 3D printed parts are connected to
    the base through printing supports. These
    supports are typically terminated directly
    with a rod in areas where the side is not
    visible. When the supports are attached
    to the visible side of the part, small balls
    are added to the top of these supports to
    prevent them from chipping off along with
    a piece of the set's part during removal.

    Sand the remaining supports with a fine grinder. Polish the part for a smooth finish.
    Cut through supports with the knife at a higher gear and low pressure.
    Trim any remaining residue with an ultrasonic knife.
    Procedure with an ultrasonic knife, such as the ZO-91 from HONDA Electronics.

    Trim any remaining residue with an
    ultrasonic knife.
    Cleaning the Part: Use a grinder to clean the entire part,
    opting for a coarser grinder if the side is not a visible face.
    Finished cleaned part, ready for gluing or painting.
    For very thin parts, use a razor saw or ultrasonic knife instead of a scalpel. A razor saw or ultrasonic scalpel is better for such parts.
    For less critical areas, roughly trim supports with a scalpel or remove them
    with a fingernail.
    After sanding, the part is ready to be installed in the model within a minute.

    I will also prepare the same part of the cockpit tub on F-16C 1/48 from Kinetic for gluing into the kit.
    Glue 3D print parts using superglue; solvent welding adhesives designed
    for plastics won't work. As in previous procedures, I first drip a few drops
    of superglue onto the coated paper after.
    With a few drops of superglue applied with a cut needle, I glue the cockpit
    interior to the plastic airframe section.
    Degrease 3D printed parts with isopropyl alcohol before painting.
    I place the cockpit assembly into the model.

    Some parts may have a visible raster, due to technological reasons.
    This can be sanded first with a coarse and then with a fine grinder
    until smooth.
    Before spraying the part with paint, I recommend spraying the part with a few coats of Mr. Surfacer 1000 first.
    Now I can apply the paint and finish the cockpit by the classic way.
    Another option is to polish the spot with a cotton swab dipped in isopropyl alcohol.
    It needs to be polished for a longer period of time. In areas that are difficult to sand
    or have details nearby, this procedure is appropriate. The material we use for 3D print
    from at Eduard is quite flexible, if you want to bend the parts, I recommend soaking
    them in hot water beforehand to soften them.
