Replimat Open Construction System 12.14.2016 ─ Timothy Schmidt 517-292-4030 timschmidt@gmail.comReplimat Open Construction System - Project Proposal Overview The Replimat Open Construction System (ROCS) 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. Goals 1. [Dis]assemble fast! 2. Minimize head tooling 3. Minimize real tooling 4. Non-destructive construction - cradle to cradle, design for disassembly 5. Standardized components drastically reduce inventory, manufacturing requirements 6. Avoid unnecessary material transformations - when possible use unmodified goodsReplimat Open Construction System - Project Proposal 7. Interoperate with existing construction systems Specifications The “right way” is the easiest to copy. Milestones I. First full physical implementation Solar power prototype deadline April 2017 Chair 15 deadline April 2017 Automated frame factory development ongoing II. First full CAD implementation Todo: get existing files posted to github, include address here. III. Incremental reduction of vitamin components Vitamins are components which cannot be manufactured by a machine built of ROCS components. Completing key development targets will allow the system to manufacture components currently sourced from commercial suppliers. BootstrappingReplimat Open Construction System - Project Proposal 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.Replimat Open Construction System - Project Proposal Printable bearings Rationale: Commonly used bearings: - - - - Axial bearing: pillow block, Thrust bearing: Combined axial / thrust bearing: Linear bearing: Current components: - 6mm balls: https://www.amazon.com/gp/product/B00SI9UM7G/ref=oh_aui_detailpage_o02_s 00?ie=UTF8&psc=1 Interoperability: Development targets:Replimat Open Construction System - Project Proposal 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 Interoperability: 1000mm frame lengths can be cut to 200mm, 400mm, 600mm, and 800mm lengths without waste.Replimat Open Construction System - Project Proposal Development targets: - Self-reproducing frame drilling machineReplimat Open Construction System - Project Proposal Sheet (coroplast) Rationale: All-purpose sheet-stock. Waterproof, resists mold and decay even when submerged in water for prolonged durations, insulating, foldable, impact and tear resistant, cuts with a knife. Useful for making boxes, shingles, buckets, backpacks, kayaks, sinks, sluices, rulers, drill guides and templates, and even some structural elements. Current components: - https://www.wensco.com/CatSearch/251/corrugated-plastic Interoperability: Development targets: - - Coroplast single-sheet casting machine to interoperate with the plastic shredder and plastic press components. (provides: fresnel lens, coroplast, single-side coro, flat sheet stock. Consumes: recycled plastic, fiber, mycofoam, epoxies, etc) White / Black single sheet coro for heat insulation / absorption References: https://www.youtube.com/watch?v=ahExsx-hBsEReplimat Open Construction System - Project Proposal Cord (550lb test nylon paracord, stainless steel cable?) Rationale: Simplified selection of knots - holding, sliding, Current components: - Commercially available 550 paracord ( https://www.amazon.com/SurvivorCord-SAFETY-ORANGE-Paracord-Conductive-Pa tent-Pending/dp/B01DAPFYMA/ref=sr_1_3?ie=UTF8&qid=1482813407&sr=8-3&key words=paracord+blanket ​ ) Interoperability: Development targets: - Printable automatic cord braiding machine https://www.youtube.com/watch?v=z9tgjUBpmLAReplimat Open Construction System - Project Proposal Box https://goo.gl/maps/Es6hfa8Q6J82 Rationale: Liquid containers are critical to several Replimat components including the battery and sink. Current components: Interoperability: Development targets: - A better bucket would be square or triangular and sit flat on the ground. And have an optional lid and paracord / coroplast / printed handle - If a 4ft square sheet is folded into a 600mm wide box, how high are the sides?

This is especially true when space is at a premium. Furniture and equipment are easier to move when they have wheels. But after you’ve moved them, they should be as stable as possible. So the casters should be easy to lock and unlock with a foot or a hand. Subcomponent count and 3D printability of existing caster designs were surveyed. Eleven revisions of test caster were designed, printed, and destructively tested to arrive at a working locking mechanism and feature construction given the constraints imposed by the FDM 3D printing process. Initial designs used 608 roller skate bearings. Later designs increased the number of axes with a preloaded bearing and decreased subcomponent count and cost by integrating printed bearing races into existing printed components. Current components: - - - - - - - 6mm stainless steel balls Stainless M8x130 bolt, nut 2x printed M8 thrust bearings Printed flexible roller (1 hour) Printed hub (1.5 hours) Printed retaining ring (0.5 hours) Printed locking lever (0.4 hours) Interoperability: Development targets: - Locking caster v12Replimat Open Construction System - Project Proposal Printable electrical switch Rationale: The printable electrical switch may be one of the only replimat components that’s more expensive than it’s commercially available counterpart. But all its subcomponents can be fully recovered and repurposed for use in other replimat components. Current components: Interoperability: Development targets: - - - Printable electrical switch v0.1 - just nuts, bolts, and printed parts Printable foot switch v0.1 - Printable tool trigger v0.1 -Replimat Open Construction System - Project Proposal Work Table Rationale: Ken Isaacs says about the work table (or 24” Module, as he called it): “the best way I know to get into Living Structures is to make a 24” cube. It’s a chance to perfect all the operations involved in larger Structures & the modules are really useful when you work with wood or metal at home. The units make good tables to mark & saw plywood & 2x2’s on. They are fine, stable tool stands for the little electric drill press. The 24” module is a good workbench for Josh. Henry & I use several as desks, typewriter tables & drawing board bases. You can bolt several modules together for larger work surfaces or small painting scaffolds.” Current components: - - - - 14x 600mm frame members 24x M8x90mm bolts + nuts 3x 600mm square sheet 2x square box drawers Interoperability: Development targets: - Drawers -Replimat Open Construction System - Project Proposal - Joy Livingwell configuration (outset front vertical posts, unmodified sheet stock)Replimat Open Construction System - Project Proposal Chairs Rationale: Sitting is such a universal activity, that no single chair could cover even a large portion of use cases. We try to cover most cases with just two extremely minimal and flexible designs. Current components: - - Portable chair v0.1 - ?x frame members - Cord - Stainless hardware Rolling chair v0.1 - ?x frame members - Cord - Stainless hardware - Locking casters Interoperability: Development targets:Replimat Open Construction System - Project Proposal Drill Press Rationale: Current components: - - - Thingiverse printable chuck 1kW+ motor Interoperability: Development targets: - - - Completion of the replimat linear bearing will allow for the construction of a linear motion system for the press mechanism Completion of the printable 1kW motor will allow for the power generating portions of the drill press to be copied Lost plastic casting, or direct metal printing will allow for a metalic version of the printable chuck.Replimat Open Construction System - Project Proposal Controller Rationale: Laser additions to open source Marlin 3D printer firmware for Buildlog.net, OpenSLS, and mUVe3D demonstrate adaptability of existing ultra-low-cost 3D printing control solutions to a wider range of problems. A collection of power, control, cooling, and container components are suggested, which connect the elements common to a variety of machine control problems, as well as additions to increase the range of acceptable input and output voltages. This allows the controller to consume power from a variety of solar panel and battery configurations, and to control peripherals originally designed for other applications (i.e. found, salvaged, or otherwise repurposed equipment).

But it’s the best place to start developing a printable cordless hand tool. It’s inexpensive (a positive feature when you need two or three). And critically, it features an interchangeable tool head system which affords it unusual versatility and reduces the volume of plastic required to 3D print a full complement of cordless tools. This reduces the time required to print the set, and shrinks the BOM as well. This faster print time and simpler BOM allow for quicker testing and iteration, and quicker replication. Interoperability with commercially available interchangeable parts increases sales of the commercial part. It also allows users of open tooling to use commercially available parts if needed, or to reuse existing parts already available to them.

This project will require detailed measurement and modeling of features compatible with the Black and Decker, Porter Cable, and Craftsman tools and batteries. And the modeling of a new attachment, featuring a [ / ]. The OpenPorterCable LiPo Battery will consist of a 3D printable battery shell, easily recycled 18650 lithium ion cells, and a common chinese balance charging circuit. This project will require detailed measuring and modeling of the Porter Cable 20v Lithium Ion battery connector, and three easily identified regions on the nearly identical Black and Decker 20v Lithium ion batteries. 2016 US retail price for 20v 4Ah Porter Cable battery is $119. Chinese generic replacement batteries are available online for $50. OpenPorterCable should be able to achieve < $20. Shooting for an order of magnitude of improvement. And OpenPorterCable will allow for much larger batteries to be built than are available from any tool manufacturer. This is one area in which Open Source Hardware can take the undisputed lead. EveryBattery: this project will require detailed measurement of a variety of commercially available power tools and batteries. As well as the detailed modeling of a set of printable adapters from each battery type to each tool type. The adapters may optionally contain a buck-boost converter capable of adjusting battery voltage up OR down, to match otherwise incompatible combinations (https://www.amazon.com/gp/product/B014OOJ0B2/ref=oh_aui_detailpage_o02_s 01?ie=UTF8&psc=1). Printable Power Handle: Detailed measurement from [tool head development] will be used in addition to original work to create a 3D printable (+ vitamins possibly including a motor, gearbox, and throttle control) power handle, compatible with the open tool head previously developed, and the commercially available tool heads.
