There are hobbyists and then there are fanatics. Jason Hatala can be categorized as both.

The machinist and fabricator, who also has a fondness for 3-D printing, recently unveiled his latest creation: a radio-controlled Caterpillar D10 bulldozer made almost entirely from 3-D printing.

"I am a member of RC Truck and Construction and enjoy building scale construction equipment,” Hatala said in an interview with

“3D printing, which I have been involved in for 4 years, has allowed me to take model building to the next step in detail and ease. I use a simple CAD program like Autodesk to design, and I use two Afinia H479s currently [to 3D print my designs with].”

To replicate the Caterpillar bulldozer, it took Hatala 10 days to design all of the 3-D printable files for the tractor, and two weeks to 3-D print the additional 270 separate parts. The only portion not 3-D printed were the track pins, which hold the 90 separate track pads, and the electronic components used to operate the remote-controlled vehicle.

According to, Hatala is currently planning to build a 1:14 scale remote-controlled 1963 Euclide R45 Dump Truck as well as a Caterpillar 657 Scraper.

Coal India Secures First-Of-Its-Kind Digital Deal

2 min
Coal India Limited has secured a new deal with Accenture Solutions to consult on enhancing mining performance and production through a digital endeavour

Coal India Limited (CIL) has appointed Accenture Solutions to digitally transform seven of its open-cast mines as the company strives to improve performance and increase coal production. Accenture is due to lay down digitalisation groundwork until March 2022.

The deal aims to increase coal production by 100 million tonnes (MT) by the end of FY’23. Once the minimum quantity has been surpassed, an agreed sum will be paid to the consultant for every additional sum of coal produced. This success fee will only be paid on the procurement of the minimum assured quantity. 

The move will see heavy earth moving machinery (HEMM) fitted with digital sensors to monitor performance efficiency at all levels. Additionally, modern data analytic techniques aim to increase mine productivity and project monitoring through functional system management and effective observation. 

An Exciting Venture For Global Mining

CIL, which aims to provide energy security in an environmentally and socially sustainable manner, hopes the move will help transform the entire business of mining operations and ensure higher volumes of coal are acquired at a lower cost. 

“This is a first of its kind initiative by the company utilising digitalisation to ramp up coal output,” CIL has said. 

A Digital Step Towards Enhanced Performance

Digitalisation is expected to take place at open-cast mines in Kusmunda, Gevra, Dipka of Southern Eastern Coalfields (SECL), Migahi, Jayant, Dudhichua, and Khadia of Northern Coalfields (NCL). Nearly 32% (188 MT) of CIL’s 596 MT output in FY’21 was accounted for by the seven selected mines. However, this new deal is set to see a large increase following the subsequent digital changes due to be made.  

“Learning from the outcome and success of this model, we may replicate it in our other large mines,” says CIL, optimistic about the future following the modernisation of their mining. 

It is expected that the move will help address roadblocks and guarantee corrective measures are put into place, ensuring the company is able to move forward with its aim of increasing output whilst remaining sustainable and eco-friendly.
