3D Printer Cantilever 2.0 C3Dt/c

Core3D

This is my latest completed project to date. I'll be happy to build one for you (see update below), but if you must go it yourself; here is the instructions for the C3Dt/c (c for cantilever) by Core3D.tech. This printer was presented at MRRF2018
It is the culmination of many of my other intructables and I will refer/link to those as needed.
The 3D printer is a Cantilever printer with the following features:

•  200mmx200mmx260mm Build volume
•  Heated bed
•  Auto Bed Leveling using inductive sensor and Aluminum bed
•  Linear Rails (MGN12 250mm) on both X and Y axis
•  Dedicated Parts cooling
•  Runing KFB2.0/Marlin 1.1.8
•  Bowden Extrusion with MK8 Extruder
•  8080 Inc 1010/1020 frame
•  Auto tensioning on X and Y Axis
•  Double Rod Lead Screw Z axis using 12mm rods for extra stability.
•  V6 All metal hotend with cooling adapter for Noctua cooling fan (ultra quiet)
•  SD card reader as well as accessible USB port for direct computer access or OctoPrint

Imprimir em 5 eixos, é, numa só frase, imprimir às curvas!

Pode parecer caricato, mas não é de beber, é antes, uma maneira de imprimir formas impossíveis com as actuais,  e imprimir objectos muito mais fortes!

Porque a base onde de imprime roda, as camadas podem ser curvas, o que permite uma estrutura muito mais resistente...

Bem pensado!

In a nutshell, this  makes the Printer lay Filament in CURVES. 
Witch allows both for print jobs not possible on today's 3D printers, and for a very strong print, as it can follow a curved deposition path.
Good Idea!

5D Printing: A New Branch Of Additive Manufacturing
Jessica Van Zeijderveld

3D printing has already been around for quite a few years. Then, a bit more than a year ago, talks of 4D printing started to circulate – which we have wrote an in-depth blog post on as well that you can read here. But now, the idea of 5D printing is being talked about and experimented with. 5D printing is not an evolved version of 3D or 4D printing as it is with audiovisual aspects of different dimensions – it is less complicated than that. You can see 4D and 5D printing as roots originating from 3D printing. In this blog post, we will first explain to you what 5D printing is, then we will tell you what the benefits are and how it can be applied. Last but not least, we will tell you what the differences are between 3D, 4D and 5D printing along with how you can keep up with the latest technological advances related to additive manufacturing.

A Gizmo Maker's life will occasionally lead him into... Woodworking!

So here's how to keep those Hand-saws fit:

Filer Guide for Hand-Saws

Mikhandmaker.

Sharpening a saw can be one of the most "difficult" tasks for a woodworker. I built this guide for sharpening hand-saw teeth at the required relief angles, for both rip saw and crosscut saw.
Inspired in an old tool from 1987 hard to achieve (at least where I live) and using materials available to anyone, I show you the step by step to make it by yourself.

•  It is very important to clarify that the files work only forward. Therefore, the force when sharpening only has to be in that direction and the backwards without pressing, thus, we will avoid premature wear of the file.

Hydraulic Ram Pump
habolooby

Pump water with no electricity, no gasoline, just gravity!

Sound crazy or impossible? Don't worry, it does obey the laws of physics, but I'll try to explain the operation later. This instructable shows how to build a fairly simple water pump that needs no energy input other than water flowing from a higher point to a lower point. Most of the pump is constructed from PVC, with a couple of bronze pieces thrown in for flavor. I was able to source all of the parts from a local hardware store (Lowes) for a bit under $100.

To function, the pump does require a reasonable amount of water that will drop at least 3'-5'. The level that the pump can raise water to depends on the water's head (total drop the water will make).

Visual 3D Print Finishing Guide

Tom Nardi

With 3D printers now dropping to record low prices, more and more people are getting on the additive manufacturing bandwagon. As a long time believer in consumer-level desktop 3D printing, this is a very exciting time for me; the creativity coming out of places like Thingiverse or the 3D printing communities on Reddit is absolutely incredible. But the realist in me knows that despite what slick promotional material from the manufacturers may lead you to believe, these aren’t Star Trek-level replicators. What comes out of these machines is often riddled with imperfections (from small to soul crushing), and can require considerable cleanup work before they start to look like finished pieces.

Mold Making & Casting Tutorial: 73-20 Figurine Mold

This
 is a basic "cut block mold" that may be used to reproduce figurines,
model parts, or small ornamental pieces. We used PlatSil 73-20 to create
 a fast, accurate mold. 73-20 is an easy to use 1:1 ratio silicone that
may be demolded in ~1hr. Upon demold, we cast an EZ Flo 60 positive.

3D Printer Job Cost Calculator



We created this little calculator for our friends who run 3D printer farms in their garage as a side business. It’s a quick way to give your customer a quote on a job. The “cost per hour” field lets you easily play with what you want to charge for printing time.

As a fun thing to do, try inputting different costs for “cheap” filament vs. “expensive” filament. Then, try adding 30 mins to the “job time” to simulate having to unclog a jammed extruder / hot-end for using cheap filament and check out the difference in final cost. This is why we put more time and energy into quality over cost.

NEPTUNE 

Are you full of crazy and exciting ideas but don’t know how to bring them to life? Maybe you think about 3D printing them, but then you realize that 3D printers cost too much money? Maybe you already have one but it's not working properly (or like they said it would), or you are new to 3D printing and want an easy to use 3D printer?

That's exactly why we created ! 

We have been active followers of 3D printing in the past few years. After monitoring news, reading comparisons, testing different models, we really couldn't decide which 3D printer could be the most appropriate one to buy for everyday use as well as professionally. Whilst there are many advantages and disadvantages of every single model, we realized that many of them were not worth the price they were selling it for. So, we developed the which is the best you can get for your money!

5 Gallon Bucket Air Conditioner

danolanater 

Hey there,

The following instructable is going to show my take on the 5 Gallon Bucket Air Conditioner/Swamp Cooler. In the picture you'll notice a small solar panel attached. I'll be creating another instructable on how to hook up a solar panel to a USB cable so you'll be able to power your bucket with solar energy. For now, this will just be about how to build an efficient bucket that actually works.

In contrast to the viral video on Youtube of the guy that built the original swap bucket, I've made a few changes to the design to make it more practical. I noticed when I first built the bucket exactly like the guy on Youtube, the ice would melt extremely fast due to the high powered fan pushing a lot of hot air past the ice. Also, a 5 gallon bucket full of ice does not provide enough of a temperature drop to cool entire rooms. And then there’s the mess that the ice leaves behind. In order to achieve maximum effectiveness, the cold air inside the bucket needed to be concentrated and aimed.

CNC Panel Joinery Notebook 

Sean Michael Ragan 

I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that today make manufacturing parts like these pretty easy. Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers. I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way, but so far, I haven’t found it. Maybe this article can serve as a jumping-off point. In any case, I think it’s time to share my notebook of CNC panel joinery. 

http://makezine.com/2012/04/13/cnc-panel-joinery-notebook/ 

Para dar destaque a quem, por compartilhar ideias, como eu, lá vai avançando isto das Engenhocas, cá vai esta simpática sugestão do nosso amigo Lucas Corato, do Grupo do Facebook Impressora 3D Brasil:

 

Sistema de "contrafortes" e "arcobotantes"   

Lucas Corato  

Gostaria de compartilhar com vocês aqui um sistema de "contrafortes" e "arcobotantes" externos para ajudar a combater o warp especialmente em peças de ABS que não grudam nem com reza braba e pai de santo.

Chamo de "contraforte" e "arcobotante" pois o conceito estrutural é o mesmo que esses elementos exercem nas catedrais góticas: conduzem as forças para fora da estrutura principal. No caso das construções medievais trata-se de forças de compressão da gravidade, mas para nós são as forças de tensão resultantes da retração do ABS..

Basicamente são peças com uma base de "orelha" desconectada da peça principal, que a partir da 5ª camada aproximadamente faz uma ponte fina, com 2-4 perímetros somente, ligando-a à peça. Dessa maneira a retração sofrida por esse apoio externo é mínima e não a faz desgrudar, mesmo que a peça principal solte. E a ponte segura o bicho no lugar. 

Na última foto verão uma peça da Delta que é complicadíssima de se imprimir em ABS, solta em 99,9% dos casos, e essa eu imprimi dessa maneira, e melhor: com a mesa fria e cola de isopor (este método da cola foi desenvolvido em conjunto ao pessoal da lsita RepRapBR)..

É fácil fácil de retirar, basta um creck pro lado (vejam foto com meu dedão) ou no máximo uma passada de estilete. E, se bem feito, não deixa praticamente nenhuma marca.Na impressão da minha extrusora uso esse sistema, vejam aqui no idler, na peça principal e no carro X, por exemplo: 

http://www.thingiverse.com/thing:428312

Pois se queriam era construír uma dessas Impressoras 3D, modelo Delta, de maior rapidez e qualidade que as de treliça, e todas em metal, aqui vejam como o podem fazer:

Delta Bot: Perfect DIY 3D Printer

Para rematar, cá vai um bom conselho da eMmachineShop, não re-inventem a roda, se precisam de fazer algo, usem o máximo de Material já em parte aquilo que vocẽs querem, isto é, Material pré-maquinado:

Pre-shaped Stock 

At eMachineShop, pre-shaped stock is material that comes in special forms other than sheets, plates, blocks or rods. For example, a round or square tube is considered a pre-shaped material. You might be able to reduce cost by specifying a pre-shaped material. For example, a shape that can be made by drilling holes in a hollow tube requires less machining time than starting with a block of material or rod. A part having a one inch square cross section may be more efficient to cut from one inch square bar stock. Note that specifying to use pre-shaped stock does not always reduce price.
