GOODesign is a design studio established in Seoul, Korea by a representative who has been active in product design and 3D CG field for 20 years. As a design company that pursues a reasonable and differentiated digital design, it has always presented a new direction through working with clients such as Hyundai Motor, Siemens Korea and beiersdorf.   This time, we have put out the life product for 3D printing by utilizing various technique design based on the shape of the Class-A surface. These products are especially the result of deep research on the 3D printing dominant shape that can not be mass-produced using a mold.

Heavy equipment is a favorite item for everyone, both adults and children. I wanted to make it print-in-place articulated for a long time, but the structure didn't come to my mind. As my design experience gained, I was finally able to make one of them, an excavator.
The print-in-place articulated method was applied, but it did not reduce the number of parts much. However, the structure of all moving parts was realized without missing. And since I paid attention to color division, you can enjoy a nice look after finishing it.

This design can be divided into three main parts (arm, upper body, and mobile/car body).
Of these, pay attention to the process of making the arm.
The process of building an arm is as follows.
1. First, pull the bucket cylinder to the top and insert it into the hole so that it can rotate.
2. Insert the piston into the arm cylinder on the back, and turn the piston into a place where the front arm (Stick) can be connected.
3. Insert the bucket by connecting it to the hole inside the bucket at the end of the front stick. At this time, do not confuse the connecting hole.
4. Insert the H-link into the front cylinder of the piston. And connect the H shape of the H-link to the bucket. Now, just insert the outer part of the H-link into the hole in the front arm (Stick).
5. Put the arm made in this way into the upper body arm (Boom). If the arm comes off well, attach it with adhesive or glue.

Please make sure to watch the video first for this process.

I'm thinking of making other heavy machinery as well, but applying the Print-in-place Articulated method takes a lot of thought. However, I am planning to make it one by one. We look forward to your expectations.

    hello,

    I would like to have the settings for this model,
    I have Tevo little monster, using simplify 3d software to convert it.

    thank you

    I love this! Scales nicely up to 150% too. Original size has very tight tolerances but is workable with PLA.

    Bigger scale print is very good solution.
    When your printing is done, Please share on our review page please.
    Thank you!

    The nice model was printed in adjusted flow, steps for used filaments. But the arm and the support on the back hangs all down. What is this?

    If you send us a picture, we are more comfortable helping you. Judging from your question alone, it looks like the cylinder and piston are loose, causing the excavator's arm to hang down.
    In this case, if you increase the material flow or the extrusion multiplier when printing the piston, the piston will become thicker and more tightly fitted to the cylinder, which will reduce the excavator arm sag.
    Thank you!

    hello,

    I would like to have the settings for this model,
    I have Creality CR-6 SE printer, using ultimaker cura software to convert it.

    thank you

    @tahsin2088
    1. Print out using high quality mode in cura.
    2. If the output is not good, try using the CR-10S Pro + cura setting file of fab365.
    The below help page will guide you how to download slicer settings.

    Aloha :-)

    I love this excavator. It was a pleasure to print. Now it's in the showroom and quite a few people have admired it.
    The crawler excavator will also be printed in the next few days ;-)

    What an extraordinary Excavator you have got!😍😍
    The printout is exceptionally smooth and neat!! We're so happy to hear that our model was on display and people were interested!
    Thank you for sharing all these great pictures and we'll look forward to the your next result.

    Can u do a add on to make the railway converter with drop down train wheels instead of the jack supports
    And if I wanted to print this in 1/43 scale what percentage would I need to scale up/down
    Thanks
    (Would love to use it on my o scale railway )

    @Carre55
    If you have a model you want, please register it on the Requests page.
    https://fab365.net/requests
    And if you want to print out 1/43 scale, please scale up 112%.
