Enclosing the Ultimaker 2, The Ultimaker Z!! Part 3

Enclosing the build volume of a 3D printer can provide several benefits, such as improved print quality, reduced warping and bed adhesion issues, and increased safety. If you're looking to enclose the build volume of your Ultimaker 2(+, extended), one option is to build an acrylic top and door for the printer.

Ultimaker 2 Toolhead upgrade

 

Luckily we have done the hard part of designing the top and door. In this post, we'll go over the steps for assembling the acrylic top and door for an Ultimaker 2(+, extended), including the necessary tools and materials, as well as any potential challenges you may encounter.

Tools and Materials

To build an acrylic top and door for the Ultimaker 2+, you'll need the following tools and materials:

  • Acrylic sheets cut to the drawings attached
  • Acrylic glue
  • X-Acto knife
  • Masking tape
  • Clamps to hold the to while the glue sets
  • 4x printed hinge pieces
  • 2x M3 x 35mm Cap screws for the hinge pins
  • Heavy duty mounting tape for attaching the hinges

Assembling the Acrylic Top and Door

  1. To begin with assembly it is best to perform a dry fit of the acrylic pieces to ensure that everything fits together nicely and you know how everything goes together. The acrylic glue doesn’t have a super long work time.
  2. Once you are satisfied with how the parts fit together remove the protective coating and mask up the acrylic to ensure the glue only ends up on the mating surfaces.
  3. Lay all of the pieces out flat on a table in the orientation that they go together. Pay careful attention to the back panel, it has a notch cut out of the left side to allow the wiring and reverse Bowden to pass through.
  4. Apply an even bead of glue to all the mating surfaces. Fold up the front and back panels before locking them in place by folding up the side panels. Apply clamps with gentle pressure before flipping the top the correct way up. Add a some weight to the top to hold the top panel in place while the glue sets.
  5. Affix two of the hinge pieces to the left side of the Ultimaker front opening with the mounting tape. Install the door panel into the opening, use small bits of card to hold the door centred, the design calls for a ~1mm gap on all sides to allow the door to swing freely.
  6. Apply the mounting tape to the other halves of the hinges, use the 35mm screws to assemble the hinges. Remove the backing from the tape and fold the hinges on to the surface of the door. Doing this while the door is positioned centred ensures the hinges are attached in the correct position.
  7. Once the glue on the top has cured, the top simply sits on top with the cables and Bowden tube passing through the small gap in the back left.

Conclusion

Building an acrylic top and door for the Ultimaker 2+ is a relatively simple project that can provide several benefits for your 3D printing setup. By enclosing the build volume, you can improve the quality of your prints, reduce warping and bed adhesion issues, and increase safety. With the right tools and materials, you can easily build an acrylic top and door for your Ultimaker 2+ and take your 3D printing setup to the next level.
