5th Generation Strengthen Builds w “Insertion”

Make composite parts on RepRap!

Looking toward the future in building Enhanced RepRap machines it accured to me that another method might be used to “Strengthen” final builds. Inserts may well be the answer to this. For example a higher strength material could be “Inserted” into the build, then given the go signal to the printer and the final build finished. Software will become the key to implementation of this idea. This could be done several ways.

Several “insert areas” could be assigned in the raft build. Say we build a square rod of higher strength plastic (the more expensive kind). Using this concept, 4 insert points would be assigned on the raft where the “Strength Square” would be inserted into the raft insert points. Once inserted the “GO” is clicked on for the software.

Another way of doing things might be to build a part to a certain level and the system build software flash for an “insert” during the middle of a build. The part or parts could be “inserted” and the build continued until completion.

Using the “ (1)Insertion” System
We add new features such as:

1) Adding a different color part into a build.
2) Adding new materials for a “complete build” in one step.
3) Add a feature, move the table to the front load area for part(s) insertion.

“Insertion” materials for possible composite builds

Off the top of my head some cheap materials.

Unwound (2)Paper Clips anyone?


Dental Floss a Great material!
How about a pre-wound coil or square using nylon? Dental floss is either a bundle of thin nylon filaments or a plastic (teflon or polyethylene) ribbon. Great material!

Springs anyone? Available in plastic, or metal

Paper Products

The list goes on…….have some ideas how about listing them.

(1) Insertion (genetics) From Wikipedia
In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. Insertions can be anywhere in size from one base pair incorrectly inserted into a DNA sequence to a section of one chromosome inserted into another.

(2) A paper clip is usually a thin wire in a looped shape that takes advantage of the elasticity and strength of the materials of its construction (usually steel or some other metal, but sometimes plastic) to compress and therefore hold together two or more pieces of paper by means of torsion and friction. Some other kinds of paper clip use a two-piece clamping system.
Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips.
