Clevanorm ready for action

Built in Blender as 8 separate pieces ( 2 of which are antennae). The legs fit into slots on the underside of the body. The body also has holes for neck and arm pins.

Much was made from simple cubes and cylinders, with use of Mirror and Boolean modifiers. One eye was made and placed, then Mirrored to get its partner. Modifier applied, then Boolean to union with Head.

One arm was made, placed, then Mirrored. Modifier applied, which makes both arms a single object. Select and separate one arm to make two objects.

Cylinders are sized and set for pins, then copied and scaled slightly larger to cut out holes. The pins can then be Boolean-ed in place.

These 8 pieces are exported as STL, and brought into Chitubox for supporting and slicing.

The initial parts – shown here – were later made larger. It is possible to scale parts up or down in Chitubox. But after first print, I re-made them in Blender, scaling them larger and re-working the arm pins and holes.

Clevanorm was printed in white Plant-Based resin Elegoo. This was my first time using the soy stuff, and I like it. It prints well and cleans up well.

I used light supports, so they came away easily, leaving no trace.

The parts assembled well, with the whole standing on its own.

For this photo only the antenna were glued in place.

The assembled pieces stands 80mm.

Printing in 3D

I’ve been curious about 3D printing for years, then decided to go for it in 2020. I picked up…

…but there a different sorts of 3D printing…

Stereolithography (SLA)

Selective Laser Sintering (SLS)

Fused Deposition Modeling (FDM)

Digital Light Process (DLP)

Multi Jet Fusion (MJF)

PolyJet

Direct Metal Laser Sintering (DMLS)

Electron Beam Melting (EBM)

Stereolithography (SLA or SL; also known as stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1987. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive. SLA

Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or called filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. “Fused filament fabrication” was coined by the members of the RepRap project to give a phrase that would be legally unconstrained in its use, under the mistaken belief that a trademark protected the term “fused deposition modeling”.
