Overview
The Replimat Open Construction System is a practical self-replicating construction system. ROCS encompases a small number of component parts reused in many different ways to construct >60 everyday tools - including several of the tools necessary to fabricate more ROCS components from raw materials.
A high degree of self-replication is achieved by carefully choosing a small number of very versatile components, and reusing those components throughout the system. Many replimat components can simply be cut to form two smaller components without creating waste. And all Replimat components are designed for disassembly, and cradle-to-cradle reusability. All component parts can not yet be replicated, though this document details a development plan to increase the number which can be. Replimat components are constructed, wherever possible, from waste plastic, unprocessed trees or reclaimed lumber, stainless steel, aluminum, or other durable, reusable, renewable, recycled and recyclable materials.
Replimat components form a durable, repurposable, mult-use carbon sink for the waste streams of other processes.
Licensing
All replimat components and documentation are available under the AGPLv3+ (https://www.gnu.org/licenses/agpl-3.0.en.html ) or TAPR OHL v1.0 (https://www.tapr.org/TAPR_Open_Hardware_License_v1.0.txt) licenses. These licenses require derivative works to be released to all parties under identical terms.
Milestones
- First full physical implementation
- Automated frame factory development ongoing
- First full CAD implementation
- Incremental reduction of vitamins components
Components
Hardware (ferromagnetic stainless steel)
Rationale
(Now favoring 316 surgical steel... more research happening) Stainless steel is a temperamental alloy. Difficult to work and produce, components made from this material can cost three times as much as a similar component in hardened steel. I believe the cost to be justified, due to the critical nature of the nuts and bolts in so many other parts of the system, and stainless steel’s extreme durability under virtually all conditions.
Offsetting the increased cost of stainless steel, the standardization on 12 total nut and bolt components across the entire system enables bulk purchasing, reduces storage and shipping requirements, simplifies inventory management, billing, and reclamation and reuse.
Stainless steels are available in magnetic, and non-magnetic varieties. The magnetic varieties tend to be less expensive, and the magnetic properties of the nut and bolt hardware are required for the operation of several components in the system - notably the solenoid pump / motor.
Current components
M3xXX, M3xYY, M3xZZ bolts, M3 lock nut, M3 washer
M8x50, M8x90, M8x130 bolts, M8 lock nut, M8 washer
M25xXX, M25xYY, M25xZZ bolts, M25 lock nut, M25 washer
1000mmx40mmx40mmx3mm bar stock - coroplast might be good enough
6mm stainless steel BBs
Interoperability
Development targets
Life cycle
Long bolts can be cut to form shorter bolts and abrasive pellets for the ball mill. Stripped, bent, or abraded nuts or bolts degrade to abrasive pellets for the ball mill.
Frame
Rationale
The modular frames in this system are constructed using only one component, repeated and assembled in a variety of configurations, with the stainless steel hardware. These frames assemble quickly, intuitively, and squarely in all dimensions and on uneven surfaces, under water, or in zero gravity. Frame members are easily manufactured from renewable and widely available raw materials such as trees, square steel, aluminum, and other metal tube, even bamboo and recycled thermoplastics. Aluminum frame members retain perfect interchangeability and reusability after years of intense sun exposure, submersion in water, etc. Wood frame members retain near-perfect interchangeability and reusability across lifetimes when stored in a home, or other controlled environment. Unlike Isaacs or Jergensen frames, Replimat uses only lengths that are multiples of 200mm, equivalent to approximately 8 inches or 5 holes. Plus two and three-hole members. This allows Replimat frames to be measured easily by sight in millimeters, inches, and holes simultaneously.
Current components
1000mmx40mmx40mm (39.37inx1.57inx1.57in) 25 hole frame Stainless steel hardware
