| ===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.

| ===Components===
| | ** part choice, translation, rotation, enumeration |
| Hardware (ferromagnetic stainless steel)
| | ** implement verbs |
| ====Rationale====
| | ** app store applications |
| (Now favoring 316 surgical steel... more research happening)
| | ** grid |
| 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
| | ** pickling, i/o - ser |
| bolts in so many other parts of the system, and stainless steel’s extreme durability under virtually all conditions.
| | ** animation - tweening |
| | | ** physics |
| 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
| | ** <del>environment models, sounds</del> |
| reuse.
| | ** <del>controller models</del> |
| | | ** <del>CSG</del> |
| 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.

| |
| ====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.
| |
| | |
| ===Printable bearings===
| |
| ====Rationale====
| |
| Commonly used bearings:
| |
| Axial bearing: pillow block,<br>
| |
| Thrust bearing:<br>
| |
| Combined axial / thrust bearing:<br>
| |
| Linear bearing:<br>

| |
| ====Interoperability====
| |
| | |
| ===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.

| 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

| |
| ====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.

| ===Cord (550lb test nylon paracord, stainless steel cable?)=== | | =Tasks= |
| ====Rationale:==== | | ==New contributors== |
| Simplified selection of knots - holding, sliding,
| | This list of items is curated especially for new contributors to the project, to provide introductory projects with which to familiarize themselves with the project infrastructure, function, and development process. |
| ====Current components:====
| | * Install the replimat [[software]] and clone the replimat git repo |

| ===Box===
| | * Outreach prep |
| https://goo.gl/maps/Es6hfa8Q6J82
| |
| ====Rationale:====
| |
| Liquid containers are critical to several Replimat components including the battery and
| |
| sink.

| ===Printable locking caster=== | | * creating / updating a project |
| ====Rationale:====
| | ===Segments=== |
| Determining the best use of space is a process, not an end result. This is especially true when space
| | * production montage |
| is at a premium. Furniture and equipment are easier to move when they have wheels.
| | ** cnc router |
| But after you’ve moved them, they should be as stable as possible. So the casters should
| | ** chop saw |
| be easy to lock and unlock with a foot or a hand.
| | ** packing |
| | * use montage |
| | ** building a project |
| | ** driving a cargo cycle |
| | ** disassembly and packing away |
| | * philosophy / voice over |
| | * closing statement |
| | * introduction |
| | * pitch |
| | * motion graphics and overlays |
|
| |
|
| 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
| | ==Director / Interviewer== |
| 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.

| ===Locking caster v12===
| |
| ===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.

| |
| ===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.”

| |
| 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).
| |
| ====Current components:====
| |
| Highly compliant input power/voltage (20 - 72v input into 180W buck converter,
| |
| suitable to be run directly from solar, salvaged batteries, spotty grid power, buck

| ===Cordless hand tool===
| |
| ====Rationale:====
| |
| This is not the best cordless hand tool. 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.

| A [generic Power Take Off / ] attachment would be a useful addition to the
| |
| capabilities of this device, and is not commercially available. 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

| the open tool head previously developed, and the commercially available tool

| | Software: |
| | * I really really want to write EDA software, but it can't be our first project unless it somehow will directly generate revenue |
| | * learn more about OpenGL to where we can write an efficient CNC toolpath previewer |
| | * implement a non-linear constraint solver for parametric 2D CAD |
| | * create a GUI to display/edit parametric constraints/dimensions similar to Fusion 360, SolidWorks, FreeCAD, SolveSpace, etc. |
| | * implement a traveling salesman algorithm for toolpath generation (Tim's used space curves before to approximate it) |
| | * implement a trajectory planner that does acceleration and maybe jerk limiting. We don't necessarily need to limit ourselves to outputting lines and arcs only, because we are in control of the hardware, not to mention you can always approximate as arcs (or lines) at the final step of post-processing |
| | * write a replacement for dxflib for importing DXFs, and use that replacement library to implement a reusable DXF geometry importer (better than the current ones out there...) |
